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 versatile integration with various engagement mechanisms, including customized shafts, motor controls, or human interface adjustments. They are ideal for controlling variable outputs such as frequency, motor speed, or volume. Key features 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. With IP54 protection and available magazine packaging for automatic insertion, these potentiometers are suitable for a wide range of industrial and consumer electronics applications, including appliance program selection, thermostat adjustment, timer and control relays, and power tool controls.
