Product Overview
The Piher PS-10 and PSC-10 are 10-mm carbon and cermet SMD potentiometers designed for applications requiring frequent adjustment. Their shaftless design allows for flexible engagement mechanisms, including customized shafts, motor controls, or human interface adjustments. These potentiometers are ideal for controlling variable outputs such as frequency, motor speed, or volume. They offer up to 10,000 life cycles, IP54 protection, and are available in embossed tape packaging. Options include linear, logarithmic, and antilogarithmic tapers (PSC-10), self-extinguishable plastic (UL 94V-0), and up to 16 mechanical detents for tactile feedback. Locating pins ensure accurate PCB positioning, and a low torque version is available. Applications span appliance program selection, thermostat adjustment, timer and control relays, consumer electronics, power tool controls, test and measurement equipment, small engines, robotics, and medical equipment control.
