S520 Submersible Rotary Position Sensor

Quick Overview

The S520 RIPS® (Rotary Inductive Position Sensor) is an affordable, durable, high-accuracy rotary position sensor designed for arduous underwater applications such as ROVs. The S520 will provide a linear output proportional to the rotary position. Each unit is supplied with the output calibrated to the angle required by the customer, any angle from 0-15° to 0-160° and with full EMC protection built in. The sensor is very rugged, being made of 316 stainless steel body and shaft with flange mounting for each installation. Environmental sealing is to IP68 350 Bar.



  • Non-contacting inductive technology to eliminate wear
  • Angle set to customer's requirement
  • High durability and reliability
  • High accuracy and stability
  • Pressure balanced for use up to 350 Bar in underwater applications
