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.
