Curtiss-Wright NRH275DR

5Vdc Dual-Redundant Output, Non-Contact, External Position Magnet.

The Penny & Giles NRH275DR is a  dual-redundant output, non-contact, rotary position sensor with a slim, low-profile sensor housing with a separate permanent magnet assembly. The NRH275DR operates from a 5Vdc (±0.5) regulated supply to each independent sensor channel, and has two independent outputs, enabling full redundancy from a very low-profile 36 x 35mm package. The NRH275DR is designed for applications in extreme environments where space is limited. It also allows up to ±2mm radial magnet offset, with a permissible air gap of 2-7mm between the sensor and magnet. The transmissive properties between the magnet and sensor also allow operation through non-magnetic materials.
