Product Overview
The Piher PT-15 and PTC-15 are 15-mm through-hole potentiometers designed for applications requiring frequent adjustment. Their shaftless design allows for integration with various engagement mechanisms, including customized 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%), carbon or cermet resistive elements, up to 38 mechanical detents for tactile feedback, and up to 100,000 life cycles. They offer IP54 protection and are available in magazine packaging for automatic insertion. Applications include appliance program selection, thermostat adjustment, timer and control relays, consumer electronics, power tool controls, and test and measurement equipment.
