Product Overview
The Piher PT-10 and PTC-10 are 10-mm through-hole potentiometers designed for applications requiring frequent adjustment. Available in carbon or cermet resistive elements, these shaftless potentiometers offer flexibility for various engagement mechanisms, including customized shafts, motor controls, or human interface adjustments. They are suitable for controlling variable outputs such as frequency, motor speed, or volume. Key features include excellent linearity (up to 3%), up to 16 mechanical detents for tactile feedback, and up to 100,000 life cycles. The series also boasts IP54 protection and offers magazine packaging for automatic insertion. Applications range from appliance program selection and thermostat adjustment to consumer electronics and test equipment.
