Resistive 320° rotary sensor for position detection in automotive applications

April 13, 2012 // By Julien Happich
The RD6R1A from Alps Electric Europe is a high-precision, long-life resistive rotary sensor for position detection in automotive applications. Available with three solder terminals, the component measures 41.5x16.0x3.5mm.

It features a hollow shaft structure of 3.53mm in diameter and covers a rotational angle of 320 degree. The total resistance depends on individual specifications. Its operating life is specified of up to 200,000 cycles. The position sensor is rated for a power of 0.1W. 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 0.1Nm. Its operating temperature ranges from –40°C to +85°C. The position sensor is available in minimum packing units of 1,800 pieces.
