Product Overview
The Piher PT-15 and PTC-15 are 15-mm through-hole potentiometers designed for applications requiring frequent adjustment. Featuring a shaftless design, they offer versatility for various engagement mechanisms, including customized shafts, motor controls, and human interface adjustments. These potentiometers are suitable for controlling variable outputs such as frequency, motor speed, and volume. Key advantages include excellent linearity (up to 3%), a choice of carbon or cermet resistive elements, up to 38 mechanical detents for tactile feedback, and an extended life of up to 100,000 cycles. They also boast IP54 protection and are available in magazine packaging for automatic insertion. Applications range from appliance program selection and thermostat adjustment to consumer electronics and test equipment.
