Product Overview
The Piher PT-10 and PTC-10 are 10-mm through-hole potentiometers designed for applications requiring frequent adjustment. These carbon and cermet potentiometers offer precise control over variable outputs such as frequency, motor speed, and volume. Their shaftless design allows for versatile engagement mechanisms, including customized shafts, motor controls, or human interface adjustments. 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 an extended life cycle of up to 100,000 cycles. They are suitable for a wide range of applications including appliance program selection, thermostat adjustment, timer and control relays, consumer electronics, power tool controls, and test and measurement equipment.
