Alps - potentiometer with LED and 24mm hollow shaft for automotive applications
With the new RK45B series, Alps Electric offers a family of new potentiometers with 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 are remarkable for their rotation angle of 180° and 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. Further technical specifications include a power consumption of 0.05W, a total resistance of 5k?, and an insulation resistance of 10M? at 50VDC. The voltage proof amounts to 50VAC per minute. With an operating temperature from –40°C to +80°C and an operating life of up to 30,000 rotational cycles, the RK45B series is an ideal solution for automotive applications, e.g. temperature and air volume control for air conditioners.
The new potentiometers are remarkable for their excellent operational feeling and a smooth click. 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.
