Smaller Than a Quarter & Thin As 0.17inches

With the diameter of 0.82in (21mm) and 0.17in (4.4mm) thinness, CP-1Hx fits any limited tight spaces. Offering high-level protection against EMS, EMI, and ESD.

Single/ Dual Output

Although this is a small potentiometer, it is feasible for offering dual output. The available analog output signal is voltage ratio output (Standard) and PWM (Pulse Width Modulation).

Wider Angle Measurement

Even though it is an unprecedented small potentiometer, wide angle measurement of up to 360° (Dead angle:0.1°) is possible.
(Mechanical angle is 360° endless.)
