Product Overview
The Piher PT-15 and PTC-15 are 15-mm carbon and cermet through-hole potentiometers designed for applications requiring frequent adjustment. Their shaftless design enables integration with various 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%), up to 38 mechanical detents for tactile feedback, and an extended life of up to 100,000 cycles. They offer IP54 protection and are available with magazine packaging for automatic insertion. Applications range from appliance program selection and thermostat adjustment to consumer electronics and test equipment.
