Proxi-Point™ 150W Connector & Wireless Slip Ring

The Proxi-Point™ 150W is a dual mode (stationary and rotating) wireless power transfer system providing a whopping 150 watts of available power, making it ideal for variable load environments.  The Proxi-Point™ 150W can supply efficient wireless power to control systems and process automation equipment in difficult, hard to reach locations where cables and mechanical connectors are just not ideal.

The Proxi-Point™ 150W is available as an Evaluation Kit at present as it is yet to be certified for FCC, CE, or EMC.


  • Dual mode capability.  Available as a stationary point-to-point connector system (Proxi-Point™), or as a wireless slip ring system (Proxi-Ring™) – delivering power across rotating joints.
  • Transfer power through any non metallic material including liquids, solids and gases
  • Corrosion and water resistant – immersion rating of IP68
  • Max continuous power is 150 W, max peak power is 240 W (up to 1 hour)
  • Plug and play system compatible with existing power supplies
  • Input reverse polarity protection
  • Output reverse current protection.  A battery on the output will not discharge into the power receiver electronics


The Proxi-Point™ is a standalone electrical device that enables transfer of power across any non-metallic material.

The Proxi-Ring™ is a standalone electrical device that enables transfer of power across an electrical rotary joint referred to as a slip ring, electric swivel, rotary electrical interface or a collector.

The Proxi-Point™  and Proxi-Ring™ are next generation solutions providing a reliable and maintenance free alternative to traditional unreliable cables, connectors and slip-rings.

Input power is transferred inductively. A standard 24 V power supply can be used to power the PP150W power transmitter. Up to 10 A peak can be drawn from the Proxi-Point™ 150W power receiver at 24V. The output voltage is held within a tight ±5% tolerance.

The Proxi-Point™ 150W is available as a plug and play modular system which can be used to upgrade power supply in new or existing equipment.


  • Continuous IP68 protection
  • Enable contact-free battery charging
  • Eliminate unreliable plugs and sockets
  • Solves continuity of delivery and maintenance pain points
  • Full contactless design for Proxi-Ring™ – elimination of friction or heating between rotating and stationary circuit contacts
  • Simplify implementation/installation processes
  • Create unique competitive advantages in the design, operation and convenience of products
  • Reduce high installation and ongoing maintenance costs
  • Immune to dust, dirt and other contaminants
  • No exposed terminals

Typical Applications

  • Automated guided vehicles
  • Forklift sensors
  • Process automation equipment
  • Hydraulic control valves and actuators
  • Forestry & construction machinery
  • Robot end effectors
  • Medical equipment
  • Revolving doors
  • Blind mating connectors
  • Quick change tooling
