Product Overview
The PT-15 and PTC-15 are 15-mm through-hole potentiometers designed for applications requiring frequent adjustment. Featuring a shaftless design, they offer versatility for various engagement mechanisms and can control variable outputs such as frequency, motor speed, or volume. These potentiometers are ideal for appliance program selection, thermostat adjustment, timer and control relays, consumer electronics, power tool controls, and test and measurement equipment. They provide excellent performance with up to 3% linearity, available with carbon or cermet resistive elements, and offer up to 38 mechanical detents for tactile feedback and up to 100,000 life cycles. With IP54 protection and magazine packaging for automatic insertion, they are a robust solution for demanding applications.
