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 with various engagement mechanisms, including custom shafts, motor controls, and human interface adjustments. They are ideal for controlling variable outputs such as frequency, motor speed, and volume. Key features include excellent linearity (up to 3%), carbon or cermet resistive elements, up to 38 mechanical detents for tactile feedback, and a lifespan 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 applications including appliance program selection, thermostat adjustment, consumer electronics, and test equipment.
