Vishay Hall effect sensor

Vishay has released a linear position sensor featuring non-contacting Hall effect technology.

Covering short electrical strokes to 10 mm max and available with a spring return system, the 20 LHE is optimised for applications in harsh environments requiring long-life sensors.

The Hall effect allows the sensor to perform in conditions involving high-frequency vibrations up to 20 G and shocks up to 50 G. With a long life of 10 million cycles, the device is suitable for short stroke measurements in industrial applications including tiller heads for forklift steering; tractor gear shifts; truck tilt sensors; and pressure measurement and pedal displacement systems.

The device features accurate linearity down to ±1 %. The sensor offers analog ratiometric or digital PWM output and provides continuous performance for the life of the device with no drift of linearity. It operates with a supply voltage of 5 ± 10 % and supply current of <16 mA typical and withstands +20 V overvoltages and -10 V reverse voltages. The recommended load resistance is 1 kΩ for analog output and PWM output.
