RVS28 28mm carbon film rotary potentiometer for welding machine


Description:


Rotary potentiometers can produce a linear or logarithmic output with tolerances of typically 10 to 20 percent. As they are mechanically controlled, they can be used to the measure the rotation of a shaft, but a single-turn rotary potentiometer normally offers less than 300 degrees of angular movement from minimum to maximum resistance. However, multi-turn potentiometers, called trimmers, are available that allow for a higher degree of rotational accuracy.


Mechanical specifications:


Total rotation angel260°±10°
Rotation torque30-200gf.cm
Stop torque≥5kgf.cm

Electrical specifications:
