Product Overview
The Piher PT-15 and PTC-15 are 15-mm carbon and cermet through-hole potentiometers designed for applications requiring frequent adjustments. Their shaftless design allows for flexible integration with various engagement mechanisms, including custom shafts, motor controls, or human interface adjustments. These potentiometers are ideal for controlling variable outputs such as frequency, motor speed, or volume. They offer excellent performance with up to 3% linearity, up to 38 mechanical detents for tactile feedback, and an extended life of up to 100,000 cycles. With IP54 protection and available magazine packaging for automatic insertion, they are suitable for demanding industrial and consumer electronics environments.
