Product Description
Product Overview
The Piher PT-10 and PTC-10 are 10-mm through-hole potentiometers designed for applications requiring frequent adjustment. Available in carbon (PT-10) and cermet (PTC-10) resistive elements, these shaftless potentiometers offer versatile control for variable outputs such as frequency, motor speed, or volume. They are suitable for a wide range of applications including appliance program selection, thermostat adjustment, consumer electronics, and test equipment. Key features include excellent linearity, up to 16 mechanical detents for tactile feedback, and up to 100,000 life cycles, with IP54 protection available.
