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 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 provide excellent performance with up to 3% linearity, and offer options for carbon or cermet resistive elements, up to 38 mechanical detents for tactile feedback, and up to 100,000 life cycles. With IP54 protection and available magazine packaging for automatic insertion, they are ideal for appliance program selection, thermostat adjustment, timer and control relays, consumer electronics, power tool controls, and test and measurement equipment.
