July 23, 2001 - Offering a fully non-contacting angular position sensor, BEI Duncan Electronics introduces the latest in steering sensor and rotary position sensing solutions. Non-Contacting Angular Position Sensor has been developed by BEI Technologies to provide a cost effective, high-resolution rotary position sensor. Initially developed for steering angle applications, Non-Contacting Angular Position Sensor is also ideally suited to a wide range of applications in a number of markets including automotive, heavy equipment, marine, instrumentation, industrial automation and robotics.

Incorporating patent pending technology, Non-Contacting Angular Position Sensor offers an extremely clever adaptation of transceiver technology and digital signal processing techniques while using a combination of well proven and durable materials in a thin package size (less than 12 mm). Non-Contacting Angular Position Sensor features mechanical memory at start-up and does not require electronic memory or a re-set function, unlike other sensing systems that cannot detect absolute position at power on. The new device is fully non-contacting and measures angular position over a full 360° range with +/- 1.5% absolute linearity.

Other outstanding features include a wide range of gear reduction and multiplication options allowing for multiple turns. Non-Contacting Angular Position Sensor is tolerant to shaft misalignment/endplay and can be packaged in through-hole, shaft drive and satellite gearing configurations. This non-contacting technology offers a wide variety of packaging sizes, some as small as 37 mm in diameter. The standard output is pulse width modulation (PWM) based on discrete surface mounted components, with analog voltage as an option. Non-Contacting Angular Position Sensor is available for ASIC development depending on production volume, packaging and output requirements. As production volumes allow, BEI Duncan Electronics can offer custom packaging engineering expertise to develop a unique Non-Contacting Angular Position Sensor solution to suit highly specific non-contacting sensor requirements .

Use of this sensor can significantly reduce packaging problems, as well as weight and power consumption requirements. Non-Contacting Angular Position Sensors can be tailored to meet desired electrical and mechanical characteristics to exactly profile unique application requirements.
