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