Non-contacting rotary position sensors offer rotational life of 50 million cycles and more

February 21, 2013 // By Christoph Hammerschmidt
Component manufacturer Bourns Inc has expanded its line of non-contacting rotary position sensors for operation in harsh environments with two new models. The Bourns Model AMS22U and Model AMM20B utilize magnetic Hall Effect (HE) technology that helps increase operational life and reliability. These non-contacting rotary position sensors are designed for use in a wide range of industrial, commercial, medical, and automotive applications such as patient platform position feedback, pneumatic control valve position feedback, actuator motor position feedback, lift/shuttle suspension systems, and tilt control feedback.

According to the vendor. the new non-contacting position sensors offer a cost-effective solution in application fields that require meets stringent reliability standards. In addition, the non-contacting sensor technology offers consistent performance over life and good performance in harsh environments resulting in reduced component replacement costs.

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

The Model AMM20B is a multiturn, non-contacting rotary position sensor that features a rotational life of up to 50 million cycles, depending on the product and particular application. The new sensor features a slim profile package for space-constrained applications, 12-bit 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 Bourns Model AMS22U is priced at $35 each in 1,000 piece quantities. The Model AMM20B is at $24 each in 1,000 piece quantities. Both models are available through Bourns' distribution sales channels.
