Curtiss-Wright NRH280DP

Dual Output, No-Contact, Rotary Position Sensor, Measurement Range from 0-20° to 0-360° in 1° Increments.

The Curtiss-Wright (Product Brand: Penny & Giles) 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.

    • No-contact technology with external position magnet
    • Unlimited mechanical lifetime – wear free
    • 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

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.

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.
