The Hall effect technology of the 981 HE device gives it the ability to perform in conditions involving high-frequency vibrations up to 20g and shocks up to 50g over a temperature range of −45°C up to +125°C, providing margins over other technologies.
With all electrical angles available up to 360° with no dead band, the device features accurate linearity down to ±0.5%. The sensor offers a long life greater than 10 million cycles for the D-shaft version, and greater than 5 million cycles for the hollow-shaft version. The 981 HE component provides continuous performance for the life of the device with no drift of linearity. Spring-loaded versions of the device are also available.
The sensor offers a supply voltage of 5V ±10%, with other values available upon request. The device has a typical supply current of 10mA, and 16mA for PWM output. The 981 HE has +20V over voltage protection and −10V reverse voltage protection. The recommended load resistance is 1 kΩ for analogue output and PWM output.
The sensor is optimised for foot pedal position sensors, throttle position sensors, steering position sensors, drive-by-wire, lift and shuttle position sensors, tilt control and tilt positioning feedback, and suspension system position sensors in marine, avionics, fork lift trucks, farm equipment, cranes, and automotive applications.
