Vishay Intertechnology, Inc. (www.vishay.com) has proudly announced the release of its latest linear position sensor that features non-contacting Hall effect technology.
Offered with a spring return system, the 20 LHE can cover short electrical strokes of up to 10 mm. It has also been optimised making it ideal for applications in harsh environments requiring sensors with long service life.
Its Hall effect technology provides the sensor the ability to perform in conditions with up to 50 G shocks and high-frequency vibrations of up to 20 G. The device offers a long service life of 10 million cycles, making it ideally suited for short stroke measurements in various industrial applications such as tillers heads for forklifting steering, truck tilt sensors, tractor gear shifts as well as pedal displacement and pressure measurement systems.
In addition, the linear position sensor provides accurate linearity down to ±1 percent. It also provides digital PWM output or analog ratiometric, while offering continuous performance for the device’s life with no drift of linearity.
The 20 LHE operates with supply current of < 16 mA typical and a supply voltage of 5 V ± 10 percent, it also can withstand + 20 V overvoltages to – 10 V reverse voltages. For PWM output and analog output, the recommended load resistance stands at 1 kW. The device has complied with RoHS directive 2002/95/EC.
