Product Overview
The Piher PT-10 and PTC-10 are 10-mm through-hole potentiometers designed for applications requiring frequent adjustment. Available in carbon (PT-10) or cermet (PTC-10) resistive elements, these shaftless potentiometers offer versatile control for variable outputs such as frequency, motor speed, and volume. They are suitable for human interface adjustments, customized shafts, or motor control mechanisms. Key features include excellent linearity (up to 3%), up to 16 mechanical detents for tactile feedback, and an extended life cycle of up to 100,000 cycles. With IP54 protection and options for magazine packaging for automatic insertion, these potentiometers are ideal for appliance program selection, thermostat adjustment, timer and control relays, consumer electronics, power tool controls, and test and measurement equipment.
