Product Overview
The Piher 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 custom shafts, motor controls, or human interface adjustments. These potentiometers are ideal 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 suitable for demanding environments.
