Penny and Giles has introduced the NRH275DR, a rotary position sensor featuring a slim, low-profile sensor housing and a separate permanent magnet assembly. The sensor is suitable for specialist vehicle applications in extreme and hostile environments where installation space may be limited.

Example applications include tip control for articulated dump trucks, bin lift control for garbage and refuse collection vehicles and four-wheel-steer function for city road-sweeping vehicles.

The lightweight, low-profile design of the sensor also means it is suitable for throttle position sensing and feedback for motorsport applications.

The NRH275DR’s fully encapsulated 12-bit Hall-effect sensor system can withstand high shock and vibration, is able to 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.

Key features and benefits

  • The NRH275DR operates from a 5VDC regulated supply and has two independent sensor power supplies and outputs that enable full redundancy.
  • The sensor is factory programmed to allow a wide range of output configurations, including CH1/CH2 angle, output type and output direction.
  • It features a low maximum output signal noise of less than 1mV, which means no additional signal filtering is required on the output signals.
  • The two-part design of the sensor and magnet assembly offers maximum flexibility when mounting, accommodating up to ±2mm of radial magnet offset and a permissible air gap of 2–5mm between the sensor and the magnet; measurements can even be made transmissively through non-magnetic materials.
  • Further flexibility is achieved as one of the sensor’s signals can be configured for use as a control function, while the other can be used for position monitoring or display purposes.
  • The NRH275DR allows OEMs to select multiple configuration options when specifying their requirements for factory programming before despatch.
  • The sensor is supplied with six 18 AWG individual wires as standard, but can also be fitted with Deutsch DTM or AMP Superseal connectors.
  • An optional NC10 plastic conduit tube can be fitted to protect the connecting wires from the sensor body to the connector.
  • The NRH275DR enables system designers to quickly and easily improve the safety and integrity of their control systems by using the dual independent power supply and output signals, ensuring compliance with SIL2 requirements for systematic safety as defined in IEC 61508.
