Anti-rotation pin hole is shown at six o'clock

position for reference only. The actual location is

determined by the customer's application. Refer

to the front view of the potentiometer to see the

location of the optional A/R pin.

Panel thickness and hole diameters are

recommended for best fit. However, customers

may adjust the dimensions to suit their specific
