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
application.
