Product Overview
The Piher PT-15 and PTC-15 are 15-mm through-hole potentiometers designed for applications requiring frequent adjustment. These shaftless potentiometers, available in carbon (PT-15) and cermet (PTC-15) resistive elements, offer versatile control for variable outputs such as frequency, motor speed, or volume. They are suitable for a wide range of applications including appliance program selection, thermostat adjustment, consumer electronics, and test equipment. Key features include excellent linearity (up to 3%), up to 38 mechanical detents for tactile feedback, and an extended life cycle of up to 100,000 cycles. They also offer IP54 protection and are available with magazine packaging for automatic insertion.
