Versatile Amphenol PT15LH05-251A2020-S potentiometer designed for control relays and test equipment
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 for versatile engagement mechanisms, these potentiometers offer precise control over variable outputs such as frequency, motor speed, and volume. They are ideal for appliance program selection, thermostat adjustment, timer and control relays, consumer electronics, power tool controls, and test and measurement equipment. Key advantages include excellent linearity (up to 3%), a choice of carbon or cermet resistive elements, up to 38 mechanical detents for tactile feedback, and up to 100,000 life cycles. The series also boasts IP54 protection and availability in magazine packaging for automatic insertion.
