Proxi-Ring 240W

Features

  • Wireless slip ring
  • Circuits completely friction free
  • Fast and accurate response to load variations with 1% accuracy
  • Power channel: maximum output current 10A (total across all channels) at 24VDC
  • Communication channel: fully integrated 250kbps wireless CAN-Bus

Description

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

The Proxi-Ring™ is a next generation solution to replace existing mechanical slip rings. It provides a reliable and maintenance free alternative and does not require friction based metal and/or carbon brush contacts to enable power and data transfer.

Input power is transferred inductively using a standard 24V power supply for the transmitter. Up to 10A peak can be drawn from the PR240W power receiver with output voltage held within a tight 1% tolerance.

The Proxi-Ring™ is available as a plug and play modular system which can be used to upgrade slip rings in new or existing equipment.

Benefits

  • Elimination of friction or heating between rotating and stationary circuit contacts
  • Cost effective maintenance free alternative to traditional slip rings
  • Unlimited continuous rotation
  • Corrosion and water proof – immersion rating of IP67
  • Plug and play modular system compatible with existing power supplies and CAN bus communication

Typical Applications

  • Hydraulic wind turbine pitch control systems
  • Hydraulic control valves and actuators
  • Forestry & construction machinery
  • Robot end effectors
  • Medical equipment
  • Revolving doors
  • Process automation equipment
  • Night navigation systems
