Vishay Intertechnology Inc. has unveiled a linear position Hall effect sensor that the company says covers short electrical strokes from 0-10mm and is available with a spring return system. The 20 LHE is geared for applications in harsh environments requiring long-life sensors, added Vishay.

The sensors can perform in conditions involving high-frequency vibrations up to 20G and shocks up to 50G. With life span of 10 million cycles, the device is ideal for short stroke measurements in industrial applications including tillers heads for forklift steering, tractor gear shifts, truck tilt sensors, and pressure measurement and pedal displacement systems, noted the company.

20 LHE

The sensors work with high-frequency vibrations up to 20G and shocks up to 50G.

The RoHS-compliant 20 LHE features accurate linearity down to 1 percent. The sensor offers analog ratiometric or digital PWM output, and it provides continuous performance for the life of the device with no drift of linearity. The sensors work with a supply voltage of 5V (10 percent) and supply current of less than 16mA typical, and withstands 20V overvoltages and -10V reverse voltages. The recommended load resistance is 1k? for analog output and PWM output. The device is compliant to RoHS directive 2002/95/EC.

Samples of the 20 LHE are available with production quantities available in 1Q12 and lead times of 12 weeks for large orders.
