Delivering an excellent linearity of ±1%, Murata Electronics has announced what it claims to be the world’s most precise surface-mount type rotary position sensors. The SVK3 series meets the usable temperature range from -40 to +125°C and 300,000 cycles service life requirements for automotive applications.

The sensors enable a previously unattainable level of control precision which enables subtle adjustments to the visibility of HUD screens or fine temperature adjustment settings to fractional values beyond the decimal point using air conditioner temperature adjustment switches. The rotary sensors have a resistance of 10kΩ and provide an effective angle of rotary movement of 333.3°.

The 11x12x2.1mm compact size and low profile, as well as the 0.4g light weight, of the rotary position sensors allow products that incorporate them to be both smaller and lighter. The physical parameters of the SVK3 rotary position sensors are identical to that of the preceding (SV03 series) products, allowing them to be used as direct replacements without the need for additional design changes.

Mass production of the SVK3 series is scheduled to begin in April 2015.
