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, 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 resistance values, and options for tactile feedback with up to 16 mechanical detents. They are suitable for various applications including appliance program selection, thermostat adjustment, consumer electronics, and test equipment. The series boasts high life cycles (up to 100,000 for PT-10), IP54 protection, and availability in magazine packaging for automatic insertion.
