Counting Instruments

ENM Counting Instruments

Panel Mounting is obtained by cutting a circular or rectangular cut-out in

the desired panel and the instrument is inserted with the flange resting

on the top of the panel. The instrument is held in place by compressing a

plastic or steel spring clip from behind the panel. This type of mounting is

very popular because it requires no additional fasteners. Models are also

considered panel mounted when they are inserted into a panel cut-out

and mounted from the front using a two or more hole flange and

fastened with screws from the front of the panel (pictured to the right).

Back of panel mounting is usually achieved by cutting an opening in a

thin panel large enough to read the display. Two or more holes are

drilled in the panel and screws are inserted from the front to secure

the instrument against the back of the panel wall.

Base mounting is usually a free standing mount and connections are

made with a two or more hole flange at the bottom of the unit. This is a

standard mount for most mechanical counters and is sometimes used

for hour meters when a panel is not available.

PCB

PC board mounting is common for using counters in add-on PCB

modules to electronic machinery. This type of mounting eliminates the

need for any wires and multiple counters can be assembled as one

unit. The counters are attached by soldering the protruding pins into the

PCB and two or more fasteners are also screwed into the bottom of the

unit for additional support onto the PC board.

Rear mounting is similar to PCB mounting except there are no pins for

soldering, only two or more holes on the bottom for threaded or self-

tapping screws. This is an optional type of mounting used mainly when

a suitable panel is not available.
