Product Overview
The PT-15 and PTC-15 are 15-mm through-hole potentiometers designed for applications requiring frequent adjustment. Featuring a shaftless design, they offer versatility for various engagement mechanisms, including customized shafts, motor controls, and human interface adjustments. These potentiometers are ideal for controlling variable outputs such as frequency, motor speed, and volume. They provide excellent performance with up to 3% linearity, available with carbon or cermet resistive elements, and offer up to 38 mechanical detents for tactile feedback. With up to 100,000 life cycles and IP54 protection, they are suitable for demanding applications in appliances, thermostats, consumer electronics, power tools, and test equipment.
