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 integration with various engagement mechanisms, including custom shafts, motor controls, and human interface adjustments. These potentiometers are suitable for controlling variable outputs such as frequency, motor speed, and volume. Key features include excellent linearity (up to 3%), up to 38 mechanical detents for tactile feedback, and a long operational life of up to 100,000 cycles. They offer IP54 protection and are available in magazine packaging for automatic insertion. Applications span appliance program selection, thermostat adjustment, timer and control relays, consumer electronics, power tool controls, and test and measurement equipment.
