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 custom shafts, motor controls, or human interface adjustments. These potentiometers are capable of controlling variable outputs such as frequency, motor speed, and volume. They offer excellent performance with up to 3% linearity, a choice of carbon or cermet resistive elements, and up to 38 mechanical detents for tactile feedback. With a life cycle of up to 100,000 cycles and IP54 protection, they are suitable for demanding environments. Available in magazine packaging for automatic insertion, these potentiometers are ideal for appliance program selection, thermostat adjustment, timer and control relays, consumer electronics, power tool controls, and test and measurement equipment.
