Murata announced what is believed to be the world’s smallest rotary position sensor. Measuring just 4.0 × 4.5 × 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° and with a useable temperature range from – 40°C to +85°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.
