Product Overview
The Piher PT-10 / PTC-10 are 10-mm carbon and cermet through-hole potentiometers designed for applications requiring frequent adjustment. Their shaftless design allows for flexible integration with various engagement mechanisms, enabling control of variable outputs such as frequency, motor speed, or volume. These potentiometers offer excellent performance, including up to 3% linearity, and are available with carbon or cermet resistive elements. Key features include up to 16 mechanical detents for tactile feedback, up to 100,000 life cycles, and IP54 protection. They are suitable for a wide range of applications including appliance program selection, thermostat adjustment, consumer electronics, and test and measurement equipment.
