Rotary position sensor expands Curtiss-Wright’s NRH27x range

Offering CANbus J1939 output for specialty vehicle applications, the NRH27C is a non-contact rotary position sensor which is suitable for use on specialty on- and off-highway vehicles using CANbus communications, says Curtiss-Wright.

The NRH27C extends Curtiss-Wright’s recently-introduced NRH271 and NRH272 family and shares many features, such as a low-profile sensor body, small footprint, CANbus J1939 communications and a fully encapsulated, IP69K-rated design that protects against water, dust, shock, vibration and temperature. This makes the range suitable for use OEMs of on- and off-highway vehicles that are intended for use in challenging environments. The NRH27C is also a cost-effective sensor for medium volume applications where a degree of customisation may be required.

Within the CAN messaging structure of the vehicle, 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. Additionally, an on-board diagnostic function means pre-defined error messages can be sent to define the present state of the sensor. The versatile, factory-programmable electronics can also be easily set to different Baud rate, node ID and frame rates according to system requirements, says Curtiss-Wright.

In addition to a CANbus SAE-J1939 output, the NRH27C is characterised by wear-free with no mechanical degredation, concentric magnet assembly offsets up to 2mm
and 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 5V DC regulated or nine to 30V DC unregulated supply. It provides a full 360 degree output range.
