Position sensors, when used together with an equipment-controlling motor actuator, are constantly influenced by the motor’s vibrations. Although slight, these vibrations wear away the pivotal resistive elements, affecting position detection accuracy. The RDC90 Series fulfills the durability requirement by incorporating a long-lasting resistive element used successfully in the past for automotive applications such as throttle position sensors.

The RDC90’s long-lasting resistive element has a specular surface, meaning friction applied to brushes sliding over the element is low, thereby minimizing noise and achieving micro-linearity (linearity in weak signal regions) within ±0.1%

Samples will be available from August 2011.
