The AMS22U and AMM20B non-contacting rotary position sensors use magnetic Hall effect technology in such applications 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 sensor that offers a rotational life of up to 100 million cycles. It features a 1/8-in. shaft supported by dual ball bearings and a factory-programmable electrical angle from 10 to 360 degrees. The AMM20B is a multi-turn model that features a rotational life of up to 50 million cycles, depending on the product and application. It has a slim-profile package, 12-bit resolution, and a factory-programmable electrical angle from 1080 to 3600 degrees. The sensors are available now in sample and production quantities. The AMS22U is priced at $35 each (1000), and the AMM20B is priced at$24 each (1000).
