Curtiss-Wright’s Industrial division has launched the NRH27C, a non-contact rotary position sensor suitable for use on specialty on- and off-highway vehicles that use CANbus communications.

Developed by Curtiss-Wright’s legacy brand of Penny & Giles, the NRH27C extends the company’s recently-introduced NRH271 and NRH272 family and shares many similar features and benefits. They include a low-profile body, small footprint, CANbus J1939 communications, and fully encapsulated IP69K-rated design that offers exceptional performance against water, dust, shock, vibration, and temperature.

Those features make the range ideal for use by OEMs of on- and off-highway vehicles used in challenging environments, and as a cost-effective solution for medium-volume applications that may require sensor customization.

Within a vehicle's CAN messaging structure, the NRH27C’s two independent Hall-effect sensing signals allow for error checking of the positional data, which addresses the needs of safety-critical applications.

Also, on-board diagnostics let predefined error messages be sent to define the sensor's present state. The factory-programmable electronics can easily be set to different Baud, node ID, and frame rates, according to system requirements.

Other advantages include: CANbus SAE-J1939 output; wear-free with no mechanical degredation; optimal combination of performance, safety, and cost; concentric magnet assembly offsets up to 2mm; multiple magnet options.

Contained in a 9.5mm low-profile housing and available with industry-standard AMP Superseal, Deutsch DT04 series connectors, or simple 18AWG flying-leads for customer termination, the NRH27C can be powered from a 5VDC regulated or 9-30VDC unregulated supply and provides a full 360° output range.
