Penny and Giles has introduced a dual redundant output version of its NRH280DP non-contact rotary position sensor, which is designed for use in extreme temperatures ranging from -40°C to +140°C and in arduous environments that are subjected to high levels of shock and vibration.

According to the company, the new NRH285DR — which operates from a 5VDC supply — can withstand temperatures of up to +170°C for 72 hours.

The IP69K-rated rotary position sensor features two independent power supplies and outputs that enable full redundancy from a low-profile housing measuring 6.5mm.

The NRH285DR is said to enable system designers to improve the safety and integrity of their control systems by using the dual independent power supply and output signals, ensuring compliance with SIL-2 requirements for systematic safety as defined in IEC 61508.

Key specifications

  • Magnet assembly activates the Hall-effect sensor, which has a permissible air gap of between 2mm and 7mm
  • Analogue (0.5–4.5VDC) or digital (pulse-width modulated) signal outputs are available as standard, but the sensor can also be factory programmed to offer 0.1–4.9VDC output to match the equivalent signals from a potentiometer
  • OEM options include a measurement range from 20° to 360° and a clockwise or anticlockwise output direction
  • Outputs can be factory programmed to include non-linear laws, switch outputs, clamp voltages, CH1/CH2 output phasing, faster input/output delay and extended analogue range
  • Electromagnetic immunity to 100V/m is ensured, as is a low maximum output signal noise of less than 1mV
