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.
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.
R
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.
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).
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.
