NRH275DR Dual-redundant output, Non-contact Rotary position sensor
NOTE: This product is now discontinued, please contact our team for other alternate solutions.
Note: This product is a non-preferred product and for new installations and applications we recommend selecting the modern equivalent NRH271 or NRH272 Non-contacting Rotary Sensors.
A dual-redundant output, non-contact, rotary position sensor with a slim low-profile sensor housing and separate permanent magnet assembly.
- Non-contacting sensor technology with external position magnet
- Unlimited mechanical lifetime – wear free
- Will operate from -40 to +140ºC
- Withstands water immersion to 1m for 24 hours (IP67)
- Simple mounting and low-profile (9.5mm) design
- Minimal weight
- 5Vdc regulated supply
- Analogue (0.5 – 4.5 or 0.1 – 4.9Vdc) or Digital (PWM) outputs
- Measurement range from 0-20º to 0-360º in 1º increments
- 12-bit resolution (0.025%) over the angular range
- Extremely low signal noise level – less than 1mVrms
- Electrically interchangeable with potentiometers
- Available with 6x 18 AWG individual wires or terminated with Deutsch DTM04-6P or AMP superseal connectors. NC10 protective conduit is also available.
NRH275DR operates from a 5Vdc (±0.5) regulated supply to each independent sensor channel and has two independent outputs, enabling full redundancy from a very low profile 36 x 35mm package.
NRH275DR has a moulded polymer enclosure with metal mounting inserts. The encapsulated Hall-effect sensor system can withstand high shock and vibration as well as operate up to +140ºC and is protected to IP67 (dust protection and water immersion to 1m depth for 24 hours). The sensor is activated by a separate magnet – available in a choice of three magnet housing styles.
NRH275DR is designed for applications in extreme environment where space is limited. It also allows up to ±2mm radial magnet offset with a permissible air gap of 2-7mm between the sensor and magnet. The transmissive properties between the magnet and sensor also allow operation through non-magnetic materials.
