Product Overview
The Piher PT-15 and PTC-15 are 15-mm through-hole potentiometers designed for applications requiring frequent adjustment. Available in carbon (PT-15) or cermet (PTC-15) resistive elements, these shaftless potentiometers offer versatility for various engagement mechanisms, including customized shafts, motor controls, or human interface adjustments. They are suitable for controlling variable outputs such as frequency, motor speed, or volume. Key features include excellent linearity (up to 3%), up to 38 mechanical detents for tactile feedback, and a long life of up to 100,000 cycles. The series offers IP54 protection, magazine packaging for automatic insertion, and is available with linear, logarithmic, and antilogarithmic tapers. Applications include appliance program selection, thermostat adjustment, timer and control relays, consumer electronics, power tool controls, and test and measurement equipment.
