Product Overview
The Piher PT-15 and PTC-15 are 15-mm carbon and cermet through-hole potentiometers designed for applications requiring frequent adjustment. Their shaftless design allows for versatile engagement mechanisms, enabling control of variable outputs such as frequency, motor speed, or volume. These potentiometers offer excellent performance with up to 3% linearity, up to 38 mechanical detents for tactile feedback, and up to 100,000 life cycles. They are suitable for a wide range of applications including appliance program selection, thermostat adjustment, consumer electronics, and test and measurement equipment.
