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°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.

The BAC05 series from Murata offers a rugged design, efficient and flexible family of AC/DC converters suitable for a wide range of applications including industrial, medical, building automation and IoT devices.
Murata have extended their range of Lithium Coin cells to include High Drain and Extended Temperature types to meet the demanding requirements of next generation IoT devices.
Murata's range AMR sensors are magnetic switches that have an integrated IC that produces high and low output digital signals based on the magnetic field strength detected.
Murata have introduced the NFG0QHB series of common mode noise filters, designed for high-speed differential interfaces such as those used on USB and HDMI interfaces.
Murata manufacture a wide range of sounder and buzzer components based on Piezoelectric ceramic technology, the range includes surface mount and through hole housed sounders and Piezoelectric diaphragms.
The LXRW series from Murata are innovative variable capacitors which allow their capacitance value to be varied by applying a voltage, the capacitance varies proportional to the voltage applied making them ideal for use in frequency tuning circuits.
