Potentiometers suit automotive applications

RK454B potentiometers offer a rotation angle of 180 degrees and offer resolutions of 0 or 17 detents per rotation.

Alps Electric has released the RK45B series of potentiometers with a red LED and 24mm hollow shaft.

The surface-mountable devices feature a compact design with 45mm in diameter and a low-profile installation of 22.2mm.

They have a rotation angle of 180 degrees and offer resolutions of 0 or 17 detents per rotation.

The necessary detent torque amounts to 55+/-203mNm or 40+/-16mNm respectively.

The components are specified for vertical PCB assembly.

They have a power consumption of 0.05W, a total resistance of 5kohm, and an insulation resistance of 10Mohm at 50V DC.

With an operating temperature from - 40C to +80C and an operating life of up to 30,000 rotational cycles, the RK45B series is an ideal solution for automotive applications, for example in temperature and air volume control for air conditioners.

To improve the illumination of the knob while retaining the compact dimensions, the LED was placed on the top of the shaft.

The RK45B series is suitable for lead-free soldering and meets the RoHS (restriction on hazardous substances) directives.
