PTC-10
10-mm carbon / cermet through-hole potentiometer
The PTC-10 potentiometer 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 volume.
■ Excellent performance (up to 3% linearity)
■ Cermet resistive element
■ Up to 16 mechanical detents for tactile feedback
■ Up to 100.000 life cycles
■ IP54 protection
■ Bulk, magazine or embossed tape (reel) packaging
■ Polyester / Alumina substrate
■ Wiper positioned at initial, 50% or fully clockwise
■ Loose and assembled shaft and knobs
■ Linear, logarithmic and antilogarithmic tapers
■ Self extinguishable plastic (UL 94V-0) available
■ SPDT switch and low torque versions available
