Product Overview
The Piher PT-10 / PTC-10 is a 10-mm carbon or cermet through-hole potentiometer designed for applications requiring frequent adjustment. Its shaftless design allows for integration with various engagement mechanisms, including custom shafts, motor controls, or human interface adjustments. This potentiometer is suitable for controlling variable outputs such as frequency, motor speed, or volume. Key features include excellent linearity (up to 3%), a choice of carbon or cermet resistive elements, up to 16 mechanical detents for tactile feedback, and up to 100,000 life cycles. It offers IP54 protection and is 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.
