7/29/2019 DATEL Application Note
1/1
Typical Meter Installations
The unique packaging of DMS Series panel meters makes them ideal for use intraditional panel-mount applications and not-so-traditional printed circuit board
applications. This application note illustrates the more popular methods of panel
mounting DATELs state-of-the-art digital panel meters. The illustrations shown aregeneric in nature and apply to all DMS-20/30/40 meters and 2-wire instruments.
Panel cutout and drill dimensions are shown in the individual product data sheets.

PANEL
Four ABS-plastic bezel assemblies are available (see Ordering Guides) for
aesthetics or environmentally-demanding applications. For those applications
requiring moisture and/or dust resistance, two bezels are offered with EPDM
sealing gaskets. The gasket is installed around the meter and seals the perim-
eter of the bezel/meter/panel interface. For added durability, all bezels feature
threaded metallic screws and inserts.
Two adapter plates are available enabling DMS meters to be installed in
irregular, "less-precise" panel cutouts. These plates can also be used to
compensate for larger cutouts encountered when designing-in DATEL meters
as alternate sources. Contact DATEL for details. The use of board-mounted
sockets simplifies installation and provides the necessary support for less-
demanding applications. Make sure the sockets are designed to accommo-
date the meters 0.025" square, solder-plated pins.
Retaining Clip Mounting
The preformed, metal retaining clip
supplied with DMS Series meters
implements a quick and secure, cost-
effective panel mounting method.
The manually installed retaining clip
provides a smooth, flush-mounted
installation that occupies a
minimal amount of front panel
real estate.
Behind-the-Panel Mounting
Many customers use this assembly method when space
is at a premium and/or a custom panel overlay is used.
DATEL offers windowed bezel assemblies (for red LED
meters only) which simply "snap" into panel cutouts.
Two windowed bezels are available.
