SVM4 series (mini PS) (left) and earlier position sensor (right)

Murata has announced what is believed to be the world's smallest rotary sensor. Measuring just 4.0 x 4.5 x 2.0 mm the SVM4 series is approximately an eighth of the size of Murata's previous position sensor the SV03. Despite its miniscule 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 - 40 degrees C to +85 degrees C 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.

Mass production is scheduled to commence during August 2015.
