Linear Position Hall Effect Sensor

Linear Position Hall Effect Sensor

Vishay Intertechnology, Inc. released a new 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 optimized for applications in harsh environments requiring long-life sensors.

The Hall effect technology of the new 20 LHE gives it the ability 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 ideal for short stroke measurements in industrial applications including tillers heads for fork lift steering; tractor gear shifts; truck tilt sensors; and pressure measurement and pedal displacement systems.

The 20 LHE 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. The 20 LHE operates with a supply voltage of 5 V ± 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. The device is compliant to RoHS directive 2002/95/EC.

Samples of the 20 LHE are available now. Production quantities will be available in Q1 2012, with lead times of 12 weeks for large orders.
