Installation and Panel Cutout
Mini M145 Series Digital Panel Meter
No mounting hardware required, snaps right into panel.
Mounting Requirements
The Mini indicators require a panel cutout of 2.68" (68mm) wide by
0.88" (22mm) high, and a panel area of 0.945" (24mm) high by 2.84"
(72mm) wide. The depth behind the panel, including terminals, is
0.7" (17.8mm). The front bezel protrudes 0.158" (4mm) from the
front of the mounting surface. The unit will snap-mount into panels
from 0.050" to 0.125" thick. A 12-pin connector with 6" wire leads is
included with each unit for quick installation.
Three power supply choices are available, and a low battery
indication is provided for 9VDC battery applications. Mini
units feature a standard 3/64 DIN, high-impact plastic case.
The standard LCD units have a clear viewing window. The
units with optional negative image, bright red backlighting,
have a red window.
