Product Overview
The Piher PT-10 and PTC-10 are 10mm carbon and cermet through-hole potentiometers designed for applications requiring frequent adjustment. These shaftless potentiometers offer versatile engagement mechanisms, including customized shafts, motor controls, or manual adjustments, making them suitable for controlling variable outputs such as frequency, motor speed, or volume. Key features include excellent performance with up to 3% linearity, a choice of carbon or cermet resistive elements, up to 16 mechanical detents for tactile feedback, and an extended life of up to 100,000 cycles. They also boast IP54 protection and are available with magazine packaging for automatic insertion. Applications range from appliance program selection and thermostat adjustments to consumer electronics and test equipment.
