New rotary position sensor

19th January 2016

Posted By Paul Boughton


Curtiss-Wright's Industrial division has announced it has launched a new non-contact, rotary position sensor from its brand family of Penny & Giles.

With an 8mm low-profile sensor body and a small footprint, this fully-encapsulated, IP68/IP69K-rated sensor offers exceptional levels of performance against water, dust, shock, vibration and temperature. The NRH300DP is suitable for use by OEMs of on- and off-highway vehicles that are destined for use in challenging environments, and as a cost-effective solution for medium volume applications where a select number of options or degree of customisation may be required.

Benefits of the new NRH300DP rotary position sensor include:

* Non-contact sensing technology provides a long mechanical life

* Can be factory set to correspond to rotations of 20° to 360° in 1° increments

* Industry-standard 38mm mounting centers – for easy replacement or upgrades

* On-board diagnostic functions allow the two outputs to be put into safe, pre-defined states should an internal sensor error be detected.

Additonal features include an innovative circuit design that allows the rotary position sensor to be powered from a regulated 5V supply or a varying voltage – such as a vehicle’s battery – in the range of 9 to 30V. Versatile, factory-programmable electronics can also be easily set to one of two analog voltage output ranges (0.5-4.5V or 0.2-4.8V) or one of three PWM frequencies.

The NRH300DP uses proven, wear-free Hall-effect sensing technology and replaces the NRH280DP for new applications. The new design features a number of magnet arrangement options, and includes an over-molded magnet carrier that simplifies the interfacing of the magnet and sensor during installation. Optional bolt, plug or loose carrier variations are also available.
