Long-life rotary position sensors

July 03, 2013 // By Graham Prophet
Bourns’ AMM20B non-contacting multiturn rotary position sensor and AMS22U non-contacting analogue rotary position sensor for applications that typically require frequent adjustment can now be ordered from distributor TTI.

Bourns designed both sensors to meet the specifications of heavy-duty applications requiring long cycle life and high reliability. The AMM20B non-contacting multiturn rotary position sensor features 12-bit resolution and factory programmable electrical angle from 1080 to 3600 degrees. Resistant to vibration and shock as well as to fluid and dust ingress, the AMM20B sensor is programmable at factory for zero position, offers a rotational life of up to 50 million cycles and is fully RoHS compliant.

The single-turn AMS22U non-contacting analogue rotary position sensor features a 1/8-in. shaft supported by dual ball bearings and a factory programmable electrical angle from 10 to 360 degrees. Available in a servo mount configuration with a rotational life of up to 100 million cycles, the fully RoHS compliant AMS22U sensor is programmable at factory for zero position and is resistant to vibration and shock as well as to fluid and dust ingress.
