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 flexible engagement mechanisms, enabling control of variable outputs such as frequency, motor speed, and volume. These potentiometers offer excellent performance, including up to 3% linearity, and feature options for tactile feedback with up to 16 mechanical detents and a long operational life of up to 100,000 cycles. They are suitable for a wide range of applications including appliance program selection, thermostat adjustment, consumer electronics, and test and measurement equipment.
