Product Overview
The Piher PS-15 / PSC-15 are 15-mm carbon/cermet SMD potentiometers designed for applications requiring frequent adjustment. These shaftless potentiometers offer versatile control for variable outputs such as frequency, motor speed, or volume. They are suitable for diverse applications including appliance program selection, thermostat adjustment, timer and control relays, consumer electronics, power tool controls, and test and measurement equipment. Key features include excellent linearity (up to 3%), carbon or cermet resistive elements, polyester/alumina substrates, up to 38 mechanical detents for tactile feedback, and up to 100,000 life cycles. They also offer IP54 protection and are available in embossed tape packaging.
