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 versatile engagement mechanisms, including customized shafts, motor controls, or human interface adjustments, making them suitable for controlling variable outputs such as frequency, motor speed, and volume. These potentiometers offer durability with up to 10,000 life cycles and IP54 protection, available in embossed tape packaging for automated assembly. They feature options for 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. Applications span appliance program selection, thermostat adjustment, consumer electronics, power tool controls, test and measurement equipment, small engines, robotics, and medical equipment control.
