Product Overview
The Piher PT-15 and PTC-15 are 15mm through-hole potentiometers designed for applications requiring frequent adjustment. Featuring a shaftless design, they offer flexibility for various engagement mechanisms like customized shafts, motor controls, or human interface adjustments. These potentiometers are ideal for controlling variable outputs such as frequency, motor speed, or volume. They provide 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, they are suitable for demanding applications. Available in magazine packaging for automatic insertion, these potentiometers are used in appliance program selection, thermostat adjustment, timer and control relays, consumer electronics, power tool controls, and test and measurement equipment.
