Product Overview
The Piher PT-15 and PTC-15 are 15-mm carbon and cermet through-hole potentiometers designed for applications requiring frequent adjustment. Their shaftless design allows for flexible engagement mechanisms, enabling control of variable outputs such as frequency, motor speed, or volume. These potentiometers offer excellent performance with up to 3% linearity, a long life of up to 100,000 cycles, and IP54 protection. They are suitable for a wide range of applications including appliance program selection, thermostat adjustment, timer and control relays, consumer electronics, power tool controls, and test and measurement equipment.
