Panel Cutout

The standard panel cutout is as shown below. (Panel cutout conforms to DIN43700.)

Panel cutout for side-by-side mounting of two or more Units

When mounting n Counters in a line, dimension A can be calculated from following formula.
A = (48n-2.5) +1, 0

Protective Cover

The Protective Cover shields the front panel, particularly the count value setting section from dust, dirt and water, and prevent malfunctioning of the Counter due to static electricity.

Note: 1. The Hard Protective Cover prevents the set count value from being altered due to accidental contact with the
pushtype thumbwheel switch.
2. The Soft Protective Cover allows the set value to be set by depressing the thumbwheel switches through it. It may be, however, difficult to make setting changes of the Counter with the Y92A-48B Protective Cover attached, which must be taken into consideration before using the Y92A-48B Protective Cover.
