Compact rotary position sensor is 'world's smallest'
Believed to be the world's smallest rotary position sensor, the SVM4 series from Murata is approximately an eighth of the size of the company's previous position sensor, the SV03. Measuring just 4.0x4.5x2.0mm, the SVM4 suits 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.
Providing a linearity of ±2%, the device has an effective rotational angle of 240° and a useable temperature range from - 40 to +85°C. This enables it to 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.
