When ordering, show model number first,
followed by EMI screen, then LED color, lens type and
terminal style.
If this is a special part, the factory
assigned modification number will be added at the end
of the ordering number.
Example: Basic model without an O-ring
panel seal, with an EMI screen, a yellow/green LED,
a diffused lens and loop terminals would be an ML1633E-Y/G-D-LT.
