Penny + Giles have launched their new low-profile, magnet-activated NRH275DR rotary position sensor, that is now available from Control Devices.
The NRH275DR only operates from 5Vdc, and has dual independent power supply and output signals (enabling full redundancy and allowing compliance with SIL-2 requirements for systematic safety as defined in IEC 61508) that terminate in 6x 18 AWG wires, allowing Deutsch or AMP style connectors to be simply added. Signal outputs are analogue (0.1-4.9 or 0.5-4.5Vdc), voltage (ratiometric) or PWM.
The factory-programmed sensor features a measurement range on each channel from 20° to 360° (available in 1° increments), and other output configurations including CH1/CH2 angle, output type and output direction. It also features a very low maximum output signal noise of less than 1mV, which means no additional signal filtering is required on the output signals.
The NRH275DR features a fully encapsulated 12-bit Hall effect sensor system that can withstand high shock and vibration, can operate at temperatures from -40°C to +140°C and is IP67-rated for dust protection and water immersion to a depth of 1m for 24 hours. Optional NC10 conduit tube protection is also available.
This new model – which joins P+G’s existing range of SRH, TPS and NRH rotary position sensors - has the same magnet style options as offered by the NRH280DP and NRH285DR models, but is supplied in a moulded polymer housing (36 x 35mm) with metal inserts for the mounting points.
With no contacting mechanical parts that can wear, the sensor is ideal for specialist vehicle applications where installation space may be limited, including articulated dump trucks (tip control), garbage collection vehicles (bin lift control), road sweeping vehicles (4-wheel steering), and racing cars (throttle pedal position).
