PTC-15
15-mm carbon / cermet through-hole potentiometer
The PTC-15 cermet potentiometers offers control where frequent adjustment is required. The shaftless design allows for employment of different engagement mechanisms, such as a customized shaft, a motor control or a human interface adjustment. This potentiometer can also control variable outputs including frequency, change in motor speed or led lighting brightness.
The PTC-15 series are available with different rotor designs and up to 15 shaft styles. This offering allows configure a custom solution for virtually any control or position feedback requirement. The result is a customized sensor that maximizes board density, reduces weight and eases assembly.
A carbon potentiometer counterpart is the PT-15.
