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, a choice of carbon or cermet resistive elements, up to 38 mechanical detents for tactile feedback, and an extended life of up to 100,000 cycles. With IP54 protection and availability in magazine packaging for automatic insertion, they are ideal for appliance program selection, thermostat adjustment, timer and control relays, consumer electronics, power tool controls, and test and measurement equipment.
