Murata Releases Most Precise Rotary Position Sensor in the World

Murata Americas has recently conquered the automotive scene with the launch of the SVK3 series, the most precise surface-mount type rotary position sensors in the world. This low profile yet compact solution delivers a linearity of ±1 percent. The sensors also attain twice the precision of previous products and can withstand temperature ranges needed by the automotive market.

Over the years, electronic controls have attained widespread acceptance in the automotive market. This is why electronic rotary switch devices are now used extensively as temperature and airflow adjustment switches in automobile air conditioning systems and for feedback control devices in drive motors. Also, rotary position sensors are used to spot the rotation state (angle) of switches or motors in these devices. As manufacturers target the addition of improved, next generation functionality to their products, there is a surge in demand for exceptionally tuned motor control and switch adjustments.

According to Geoff Brock, General Manager, New Products & Sensors, Business Development & Product Marketing, Murata Americas, Murata developed the SVK3 series in response to this growing demand. He explained that this solution raises control to a higher level, delivering the globe’s most precise SM rotary position sensors.

Thanks to the SVK3 rotary position sensors’ compact size, low profile (W11 × L12 × T2.1mm) and lightweight (0.4g) dimensions, the products incorporating them are miniaturized. The physical parameters of these new sensors are identical to that of its predecessor (SV03 series), enabling them to be used as direct replacements without the need for extra design changes or performance degradation.

Moreover, the sensors meet the service life (300,000 cycles) and temperature range (-40 to 125 degrees C) requirements for automotive applications. The all-new SVK3 series SM rotary position sensors have a resistance of 10k ohms and offer an effective angle of rotary movement of 333.3 degrees.
