Product Overview
The Piher PT-15 and PTC-15 are 15-mm through-hole potentiometers designed for applications requiring frequent adjustment. Featuring a shaftless design, they offer versatility 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 deliver excellent performance with up to 3% linearity, a choice of carbon or cermet resistive elements, and up to 100,000 life cycles. The series also offers features like IP54 protection, magazine packaging for automatic insertion, and optional SPDT switches and low-torque versions. Applications include appliance program selection, thermostat adjustment, timer and control relays, consumer electronics, power tool controls, and test and measurement equipment.
