Resistive 320 degree rotary sensor enables position detection in automotive applications

April 12, 2012 // By Paul Buckley
ALPS Electric Europe GmbH has introduced the RD6R1A a high-precision, long-life resistive rotary sensor for position detection in automotive applications.

Available with three solder terminals, the component has dimensions of 41.5 mm x 16.0 mm x 3.5 mm (L x W x H). It features a hollow shaft structure of 3.53 mm in diameter and covers a rotational angle of 320 degree. The total resistance depends on individual specifications.

The device’s operating life is specified of up to 200,000 cycles. The position sensor is rated for a power of 0.1 W. Other technical specifications of the RD6R1A include a total resistive tolerance of ±20%, an absolute linearity of ±2.2% (320°) and a rotational torque of 0.1 Nm. The device’s operating temperature ranges from -40 to +85°C. The position sensor is available in minimum packing units of 1,800 pieces.
