Product Overview
The PT-10 and PTC-10 are 10mm carbon and cermet through-hole potentiometers designed for applications requiring frequent adjustment. These shaftless potentiometers offer versatile engagement mechanisms, including customized shafts, motor controls, or human interface adjustments, enabling control of variable outputs such as frequency, motor speed, or volume. Key features include excellent performance with up to 3% linearity, a choice of carbon or cermet resistive elements, up to 16 mechanical detents for tactile feedback, and an extended life of up to 100,000 cycles. They also boast IP54 protection and are available with magazine packaging for automatic insertion. Applications include appliance program selection, thermostat adjustment, timer and control relays, consumer electronics, power tool controls, and test and measurement equipment.
