Product Overview
The Piher PT-15 and PTC-15 are 15-mm through-hole potentiometers designed for applications requiring frequent adjustment. Featuring a shaftless design, they accommodate various engagement mechanisms like customized shafts, motor controls, or human interface adjustments. These potentiometers are suitable for controlling variable outputs such as frequency, motor speed, or volume. They offer excellent performance with up to 3% linearity, carbon or cermet resistive elements, and up to 38 mechanical detents for tactile feedback. With a lifespan of up to 100,000 cycles and IP54 protection, they are ideal for appliance program selection, thermostat adjustment, timer and control relays, consumer electronics, power tool controls, and test and measurement equipment.
