Small-form-factor rotary position sensor

April 16, 2015 // By Graham Prophet
Murata has announced what it believes to be the smallest-available rotary position sensor. Measuring 4.0 x 4.5 x 2.0 mm the SVM4 series is approximately one-eighth of the size of Murata's previous position sensor the SV03.

Despite its dimensions the SVM4 exhibits a linearity of ±2% and suits a wide variety of space-constrained applications such as finger-joint controllers in humanoid robots or to provide angular control in very compact spaces such as in radio-controlled model and game console controllers.

The effective rotational angle is 240 degrees and with a useable temperature range from - 40C to +85C it can be used in most operating environments. Other potential applications for the SVM4 include use in wearable devices such as headsets and hearing aids or as a lens/iris feedback sensor in compact digital cameras.
