In our consumerist, open market economy, we have been taught to shop for the best price. You’ve heard the statement, “nobody pays list retail price anymore.” At the same time people will tell you to be careful when looking at two items to make sure you are truly getting an “apples to apples” comparison.
Today, the majority of industrial companies have professional buying organizations whose job it is to make sure they get the best price on components they buy. However, many times when they go shopping they get lost in the fruit aisle and come home with a lemon instead of an apple.
So why does this happen. These are very conscientious people working hard to save money for their company and get what the production team needs to optimize the business. The problem is that sometimes the price tag covers up the fruit and they don’t realize how good or bad it is until they get it home. To make better decisions it is necessary to look behind the price tag. This is called Product Lifecycle analysis.
Here’ a basic example, you buy a mechanical connector for $30 and it takes an electrician to install it that costs you $45. From the simple price tag view this connector cost you $75. However, this connector experiences a failure once a year due to corrosion or frictional wear. So the next year you have to buy another connector for $30, it takes an electrician to replace the old one, only this time it is at night and you have to pay call time, so it costs you $100 to replace. Also, while that connector was failed, the production line was down for 1 hour that cost you $160. So that $75 connector in a 12 month period has actually cost you $365. And guess what – that keeps occurring each year, so after 48 months you have spent $1,235 on that connector choice.
Compare that with a Proxi-Point non-contacting connector. Let’s say you buy the unit for $300, 10 times more than the other connector. You then pay $45 to install it. The non-contacting connector, with all of the traditional causes of connector failure eliminated, lasts for 48 months with no maintenance. When you look at your fruit bill over the four years, the traditional, less expensive connector has cost you $1,235 while the non-contacting one has cost you $345. That’s a lot more fruit you could have purchased.
So, next time your purchasing team is looking to help you buy connectors, steer them down the aisle to true savings. Go contactless, go Proxi-Point.
Often times we find ourselves wishing that things were different. We play the “what if” game. Unfortunately this isn’t limited to our personal lives, it also applies to the way we approach our jobs.
Often times, we know that we have a problem that just keeps occurring and we assume that it is just how it has to be. It’s always been that way, smarter people than me have tried to change it, but it is still happening. I find this to be true with engineers when it comes to electrical connectors. Their local connector distributor comes in with the latest design that they guarantee will fix the problem. They are skeptical, but try it. When they first put it in it seems better, but at the worst possible time, the new connector fails just like the old one did. Maybe it lasted two months longer, so a little improvement, but it just cements the thought that this problem just cannot be fixed. You hate being called to the plant in the middle of the night to fix it, but what else can you do?
PowerbyProxi has worked with companies to develop non-contacting connectors called the Proxi-Point. The Proxi-Point can be sealed to IP 69 level, deliver power from watts to kilowatts, has no moving parts or frictional connection, allows for the direct replacement of current mechanical connectors while offering a high reliability, no maintenance solution.
I know, you’re saying, why try it, it will just end up like every other connector I have tried. Unlike the next generation contacting connector, a non-contacting connector truly eliminates the sources of connector failure.
Isn’t it time you show everyone that those other people really weren’t smarter than you?
PowerbyProxi presents: “Powering Sensors in Hostile Environments”
Alternative & Renewable Energy Open
April 27th 3:30 – 4:30 pm EDT
FREE Online Event Sponsored by GlobalSpec
April 27, 2011 – Power-by-Proxi invites you to attend a free online seminar, featuring Fady Mishriki, CEO/Business Development & Co-founder who will present “Powering Sensors in Hostile Environments”.
In this presentation, attendees will learn of a contactless slip ring that provides wireless power and data to pitch control systems in wind turbines. This improves wind turbine efficiency by reducing the cost of maintaining and replacing existing mechanical slip rings and their carbon brushes, especially in wet, dirty environments, where rotational movement is involved, and power cables and physical connectors are problematic, expensive, and unreliable. Power transfer without wires or frictional contact ensures sensor operation in hard-to-reach locations. Replacing traditional wiring harnesses with wireless power transmitters and receivers ensures reliable sensor operation in hostile environments, in applications involving rotational movement, and in hard-to-reach locations.

PowerbyProxi, developers of high-efficiency, industrial wireless power solutions, have introduced alternative power technologies that reduce or avoid the problems of brush slip ring designs. The company’s contactless slip rings transmit power and data between stationary and rotating frames without the use of conventional slip rings or brushes. In these devices, there is no physical contact between the rotating and fixed parts of the apparatus. Inductive components are used to provide a reliable and efficient transfer of electrical power and data across the rotational boundary.
Fady Mishriki, CEO and Co-Founder of PowerbyProxi says “The conventional approach of using a mechanical slip ring to transfer power and data can be problematic, expensive and unreliable. By eliminating friction-based connection failures, wireless power transfer can reduce operation and maintenance costs, preserve data continuity, and free designers to create innovative solutions.”
For example, our contactless slip ring solutions, offers these capabilities:
1. Provides cost-effective, maintenance-free alternative to mechanical slip ring devices
2. Eliminates friction or heating between rotating and stationary components
3. Provides highly efficient transfer of power and data across short distances through inductive power transfer.
4. Enables complete freedom of movement (360° continuous rotation) across rotary joints, unlimited RPM and no need for lubrication and cooling.
5. Replaces through-hole slip rings and other wired electrical connectors. Proxi-Ring components can be manufactured for easy “plug and play” replacement of existing mechanical slip ring components.
3 applications where contactless slip rings provide substantial benefits:
Traditionally, DC servo motors have been used for wind turbine pitch control actuation. However, the trend toward larger turbines, increasingly isolated installations, and continued use of operate until failure maintenance practices drives down reliability and increases the total cost of energy (COE) of wind power operations. Also, slip ring devices fail frequently and require regular maintenance, cleaning and brush replacement, which results in expensive downtime.
Adding brushless PowerbyProxi slip rings and dynamic harmonization control technologies to wind turbine pitch control systems during the design and operations-maintenance phases of the turbine lifecycle can improve performance and reduce operations and maintenance costs. Proxi-Ring technology includes no moving parts, which can fail or cause false restarts. Wireless power solutions can reduce wiring failures. And, PowerbyProxi technology provides unlimited and continuous rotation speeds, which enable wind turbine designs to operate in variable load operating environments.
Like wind turbine applications, PowerbyProxi radar solutions provide 360° continuous rotation across rotary joints. However, these solutions also require continuous data transmission to enable safety and technical analysis. PowerbyProxi solutions are designed to operate in a wide variety of communications systems. Fully integrated wireless data supports most industrial protocols, including CAN-Bus (J1939), RS 485, RS 422, Ethernet, and PLC (4-20mA).
Heavy machinery in extreme environments.
PowerbyProxi solutions are also designed to operate in heavy machinery that operates in wet, dirty, or other hostile environments. The company’s first Proxi-Ring system was a forestry solution. It had to be highly corrosion resistant, able to withstand extreme heat, cold and humidity, and survive shocks of up to 50 Gs. These capabilities, high power transmission reliability, and plug-and-play installation reduced the cost of replacing hard-cabled power alternatives.

Industrial designers, engineers and manufacturers in industries that employ machinery with rotating parts or operate in hostile or hard-to-reach work environments need new ways to ensure continuous data transmission and reduce critical downtime that occurs from failed electrical and mechanical connectors.
Slip ring technology was developed to overcome the constraints of power cables and mechanical components, which can increase maintenance costs in hostile environments and limit design options in applications that use moving parts.
Carbon brush slip rings were an early design alternative. These electromechanical components when used with brushes, provide a continuous electrical connection between rotating parts and stationary conductors. However, these devices incur downtime due to failed electrical and mechanical connectors. Mechanical, through hole, and high-current slip ring designs also limit designers’ and manufacturers’ ability to power systems in wet, dirty or hostile conditions that involve vibration and 360 degree movement.

Evaluation kits now available to test solutions to reduce operations and maintenance costs from electrical failure
CINCINNATI – November 18, 2010 – Industrial designers, engineers and manufacturers in industries that employ machinery with rotating parts such as wind turbines, radar and heavy machinery now have a new way to avoid critical downtime that occurs from failed electrical and mechanical connectors. Mechanical slip rings, through-hole slip rings and high-current slip rings often limit designers’ and manufacturers’ ability to power systems in wet, dirty or hostile conditions which involve vibration and 360 degree movement. PowerbyProxi, a provider of high-efficiency, industrial wireless power solutions, today announces the availability of evaluation kits to measure the benefits of replacing traditional electrical components and electrical connectors in difficult to access or challenging operational environments with wireless slip rings and connectors.
Fady Mishriki, Vice President of Applications for PowerbyProxi says “The conventional approach of using a mechanical slip ring to transfer power and data can be problematic, expensive and unreliable. By eliminating friction-based connection failures, wireless power transfer can reduce operation and maintenance costs, preserve data continuity, and free designers to create innovative solutions.”
PowerbyProxi’s industrial wireless power solutions provide highly efficient transfer of power and data across short distances through inductive power transfer. Proxi-Ring is a frictionless, contactless slip ring, which supplies wireless power to rotating, highly mobile industrial equipment. This solution is an electrical device with no moving parts or friction-based components. Proxi-Ring enables complete freedom of movement (360° continuous rotation) across rotary joints, unlimited RPM and no need for lubrication and cooling. Proxi-Ring solutions include replacements for through-hole slip rings, and other wired electrical connectors. The components can be manufactured for easy “plug and play” replacement of existing mechanical slip ring components.
PowerbyProxi’s Proxi-Wave technology is unique in its ability to cater for the demands of variable load operating environments and overcomes the limitations of earlier generations of Inductive Power solutions that suffered from excessive heat generation.

PowerbyProxi is commercializing wireless power transfer (WPT) technology in applications for the manufacturing, aviation, and agricultural industries. These industrial applications have put WPT on the radar of business analysts such as Frost & Sullivan.
Recently, we spoke with Frost analysts about our technology, resulting in Advanced Manufacturing Technology Alert which can be found here (free registration required).
The report highlights some key advantages of PowerbyProxi solutions to deliver efficient, cable-free power in extreme conditions.
The trend toward larger wind turbines, increasingly isolated installations and continued use of operate-until-failure maintenance practices drives down reliability and increases the total cost of energy (COE) of wind power operations.
As a result, wind turbine OEMs continue to search for innovative wind turbine designs with improved performance and lower COE. And, wind turbine project operators are interested in more cost-effective alternatives to aging turbines that are increasingly expensive to maintain.
At the show we talked with wind turbine manufacturers and operators about the role of pitch control in operational efficiencies. Modern wind turbines adjust rotor blade pitch angle for safety and control.Pitch control optimizes blade performance and therefore, overall turbine performance. However, to be cost-effective, pitch control systems require high levels of uptime.
Correcting pitch control system failures or false resets require substantial maintenance costs. And, optimal turbine performance can be limited by factors such as turbine design, turbine location and the need of high levels of data and power availability.
Wireless slip rings are an innovative method for wirelessly transmitting power or data between stationary and rotating frames without the use of conventional slip rings or brushes. In these solutions, there is no physical contact between the rotating and fixed parts of the apparatus. Inductive components are used to provide a reliable and efficient transfer of electrical power across the rotational boundary, reducing maintenance costs and improving overall uptime for the operator.
