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