PT-10 / PTC-10: 10-mm Carbon / Cermet Through-Hole Potentiometer
Product Overview
The Piher PT-10 and PTC-10 are 10-mm carbon and cermet through-hole potentiometers designed for applications requiring frequent adjustment. Their shaftless design allows for versatile engagement mechanisms, including customized shafts, motor controls, or human interface adjustments, enabling control of variable outputs such as frequency, motor speed, or volume. These potentiometers offer excellent performance with up to 3% linearity, a wide range of resistive elements, and options for tactile feedback with up to 16 mechanical detents. They are suitable for demanding environments with IP54 protection and a long operational life of up to 100,000 cycles.
