Enabling the Electronics Revolution PT-10 / PTC-10 10-mm carbon / cermet through-hole potentiometer The PT-10 and PTC-10 potentiometers offer 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. KEY FEATURES Excellent performance (up to 3% linearity) Carbon or cermet resistive element Up to 16 mechanical detents for tactile feedback Up to 100.000 life cycles IP54 protection Magazine packaging for automatic insertion available 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 version available U p to 100k IP 5 4 On request U p to 1 6 E xtra -lo ng F lame de te nts life re tardant Embossed tape packaging ELECTRICAL SPECIFICATIONS APPLICATIONS Appliance program selection PT-10 PTC-10 Thermostat adjustment Taper Lin, Log, Alog Timer and control relays Range of values (Decad. 1.0 - 2.0 - 2.2 - 2.5 - 4.7 - 5.0) Consumer electronics Lin 100 Rn 5M Log, Alog 1K Rn 5M Power tool controls Tolerance Test and measurement 100 Rn 1M 20% equipment 1M Rn 5M 30% Max.
