ORDERING INFORMATION

When ordering, show basic part number first, then EMI screen, LED color, lens type, terminal style and voltage. If this is a special part, the factory assigned modification number will be added at the end of the ordering number.

Example: Basic model with an EMI screen, with a red/green LED, a diffused lens, straight terminals and 24 volt internal resistor would be an ML 1634 E-R/G-D-ST

ML 1634 - E - R/G  - D - ST - S ( )           
Basic Model Number EMI Screen LED.
Color 		Lens Type Terminal Style Factory Modification Number if Special
ML 1634 ( ) None R/G Red/Green ND Non-Diffused ST Straight Leads S.+ ID No.
  E Screen Y/G Yellow/Green D Diffused LT Loop terminals
