Product Overview
The Piher PT-15 and PTC-15 are 15-mm through-hole potentiometers designed for applications requiring frequent adjustments. Featuring a shaftless design for versatile engagement mechanisms, these potentiometers are ideal for controlling variable outputs such as frequency, motor speed, or 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 lifespan of up to 100,000 cycles and IP54 protection, these potentiometers are suitable for demanding applications including appliance program selection, thermostat adjustment, consumer electronics, and test and measurement equipment.
