Product Overview
The Piher PT-15 and PTC-15 are 15-mm through-hole potentiometers designed for applications requiring frequent adjustments. Featuring a shaftless design, they offer flexibility for various engagement mechanisms like customized shafts, motor controls, or human interface adjustments. These potentiometers are suitable for controlling variable outputs such as frequency, motor speed, or volume. They are available in carbon (PT-15) or cermet (PTC-15) resistive elements, with options for up to 38 mechanical detents for tactile feedback, and up to 100,000 life cycles. The series boasts IP54 protection and is available in magazine packaging for automatic insertion. Key applications include appliance program selection, thermostat adjustment, timer and control relays, consumer electronics, power tool controls, and test and measurement equipment.
