Product Overview

The HRPM Hall-Effect Rotary Position Sensor from Piher offers 360-degree absolute position feedback with endless mechanical rotational angle and no dead band. It maintains position on power loss and features configurable electrical angles from 50 to 360 degrees. Designed for harsh environments, this cost-effective, non-contacting sensor utilizes a touchless concept with separate housings for electronics and a magnet, significantly increasing reliability and lifetime. Its fully sealed and flanged-mounted design ensures easy positioning and versatility, with options for bare or housed magnets, different pin-outs, and support for low and high-voltage power supplies. Applications span industrial, transportation, marine, and home and building automation sectors, including robotics, valve monitoring, steering wheels, pedals, and HVAC systems.
