Product Overview
The PT-15 and PTC-15 are 15-mm through-hole potentiometers, available in carbon or cermet, designed for applications requiring frequent adjustments. Their shaftless design allows for versatile engagement mechanisms, including customized shafts, motor controls, or human interface adjustments. These potentiometers are capable of controlling variable outputs such as frequency, motor speed, or volume. Key features include excellent linearity (up to 3%), up to 38 mechanical detents for tactile feedback, and up to 100,000 life cycles. They offer IP54 protection and are available with magazine packaging for automatic insertion. Applications span appliance program selection, thermostat adjustment, timer and control relays, consumer electronics, power tool controls, and test and measurement equipment.
