Compact Amphenol PS10KH40-503A3030 potentiometer with polyester alumina substrate and self-extinguishable plastic

Product Overview

The PS-10 and PSC-10 are 10-mm carbon/cermet SMD potentiometers designed for applications requiring frequent adjustment. Their shaftless design enables integration with various engagement mechanisms, including customized shafts, motor controls, or human interfaces. These potentiometers are suitable for controlling variable outputs such as frequency, motor speed, or volume. Key features include IP54 protection, up to 10,000 life cycles, and options for linear, logarithmic, and antilogarithmic tapers (PSC-10). They are available in embossed tape packaging for automated assembly and can be equipped with up to 16 mechanical detents for tactile feedback. Applications span appliance program selection, thermostat adjustment, consumer electronics, power tool controls, and medical equipment control.
