A pair of non-contacting rotary position sensors has been recently unveiled by electronic component maker Bourns Inc. The AMS22U and AMM20B use magnetic Hall Effect (HE) technology, addressing product lifespan and reliability in rugged environments. The sensors are ideal for applications such as patient platform position feedback, pneumatic control valve position feedback, actuator motor position feedback, life/shuttle suspension, and tilt control feedback.

The AMS22U is a single-turn, non-contacting rotary sensor that offers a rotational life of up to 100 million cycles for superior longevity and reliability. It features a 1/8-inch shaft supported by dual ball bearings and a factory programmable electrical angle from 10 to 360 degrees.

The AMM20B is a multi-turn, non-contacting rotary position sensor that features a rotational life of up to 50 million cycles, depending on the product and particular application. It has a slim profile package for space-constrained applications, 12bit resolution and a factory programmable electrical angle from 1080 to 3600 degrees.

The non-contacting rotary position sensors are available now in samples and production quantities. As a pricing reference, the AMS22U is priced at $35 each in 1,000 piece quantities and the AMM20B is priced at $24 each in 1,000 piece quantities.
