NRH280DP Series
Dual Output, No-Contact, Rotary Position Sensor, Measurement Range from 0-20° to 0-360° in 1° Increments.
The NRH280DP is a dual output, no-contact rotary position sensor with the slimmest low profile housing, using a factory programmable Hall effect sensor system. Non-Contact with external positions magnet the NRH280DP has a co-molded fully encapsulated sensor system that can withstand high shock and vibration as well as operate up to +170°C, and endure high-pressure wash-downs (IP69K). The sensor is activated by a separate magnet with a choice of two carrier designs.
For new installations and applications, we recommend selecting the modern equivalent NRH300DP no-contact rotary position sensor, which has the same mounting profile and magnet options.
-

- Will operate from -40 to +140°C, with excursions to +170°C
- Withstands high pressure wash-downs (IP69K)
- Simple mounting and extremely low profile (6.5mm) design
- Minimal weight
- 5Vdc or 9-30Vdc supply
- Analog (0.5 – 4.5 or 0.1 – 4.9Vdc) or Digital (PWM) outputs
- Measurement range from 0-20° to 0-360° in 1° increments
- 12-bit resolution (0.025%) over the angular range
- Extremely low signal noise level – less than 1mVrms
- Electrically interchangeable with potentiometers

NRH280DP is designed for applications in extreme environments where space is limited. It also allows up to ±2mm radial offset, with a permissible gap 2-7mm between the sensor and magnet. The transmissive properties between the magnet and sensor also allow operation through non-magnetic materials.
