• 3/64 DIN Indicator
• Minimum depth - requires less than 0.7”
• Snaps right into panel - no mounting
Mounting Requirements
The Mini indicators require a panel cutout of 2.71" (68.8mm) wide by
0.89" (22.6mm) high, and a panel area of 0.94" (24mm) high by 2.83"
(72mm) wide. The depth behind the panel, including terminals, is 0.7"
(17.8mm). The front bezel protrudes 0.16" (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.
