The RS15H12AA009 is a slide potentiometers dual unit 15mm horizontal type. It is manufactured by ALPS and is designed with two dual-in-line (DIP) circuits mounted onto a single 15mm length slider. The potentiometer features two-lines of terminals on each side and the slider knob is positioned to either side of the device. The linear taper provides a smooth and linear output voltage transition when incremented. It is a single-gang dual unit that is resistant to moisture and dust. The sliding friction is 150mO and the rated input voltage of this device is 5V. The rotational life is 10,000 cycles and it has a temperature range of -20°C to +85°C. Terminals are available on both ends and the device has a temperature coefficient of 0~+-100 ppm/°C.
