Product Overview
The Piher PT-15 and PTC-15 are 15-mm through-hole potentiometers designed for applications requiring frequent adjustment. These shaftless potentiometers offer versatility through various engagement mechanisms, including customized shafts, motor controls, or human interface adjustments. They are suitable for controlling variable outputs such as frequency, motor speed, or volume. Key features include excellent linearity (up to 3%), carbon or cermet resistive elements, up to 38 mechanical detents for tactile feedback, and a long operational life of up to 100,000 cycles. With IP54 protection and available 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.
