Penny + Giles has introduced the NRH280DP, a new dual output ‘no contact’ rotary position sensor.
The NRH280DP uses proven, non-contact programmable Hall-effect technology to provide OEMs with highly reliable and accurate rotary measurement in extreme industrial and off-highway environments. This low-profile sensor, with a 6.5mm profile, one of the thinnest available, provides numerous programmable options. Designed for operation in extreme temperatures, the NRH280DP enables system designers to quickly and easily improve the safety and integrity of their control systems.
The rugged NRH280DP is ideal for use in arduous operating environments and is currently used in diverse applications including articulated dump trucks (tip control), garbage collection vehicles (bin lift control), road sweeping vehicles (4-wheel steering), and Formula 1 racing cars (throttle pedal position).
Performance Features:
* Dual outputs
* “No Contact” Hall-effect technology
* Supports air gap between 2-7mm
* Low-profile: 6.5mm profile
* Power requirements: 5Vdc regulated or 9-30Vdc unregulated power supply
* Over-voltage protection to 40Vdc
* User programmable with 341 different angles (0-20 to 0-360 degrees: in one degree increments)
* 12-bit resolution (0.025%) over selected angular range
* Analog (0.5 to 4.5Vdc) or digital (Pulse Width Modulated) signal outputs
* Factory programmable to 0.1 to 4.9Vdc output range
* Electromagnetic immunity to 100V/m (<1mV maximum output signal)
* ±0.4% non-linearity
* Operating temperature range: -40 to +140ºC @ 5Vdc (< ±30ppm/ºC stability)
Unlike conventional captive shaft rotary position sensors, the NRH280DP has a separate magnet assembly that activates the fully encapsulated Hall-effect sensor with a permissible air gap of between 2 and 7mm. This allows the sensor to be used in extreme environments that are subjected to high shock and vibration, or can endure high-pressure wash-downs (IP69K protected).
