NRH27C Series

No-Contact, CAN-bus Rotary Position Sensor.

The NRH27C is a CAN-bus output sensor from the family of NRH27x No-Contact, Rotary Position Sensors that offers the optimal combination of performance, safety and cost.

All variants utilize proven Hall effect, sensing technology and are accommodated in a low-profile (9.5mm) housing with a compact footprint of just 36 x 35mm.

A fully-encapsulated design offers exceptional levels of performance with respect to water and dust, shock, vibration and temperature, meaning the sensor is ideal for use in hostile, on- and off-highway vehicle environments.

A Cost-effective solution for medium volume applications where a degree of customization may be required.
