Ordering as a Set
The model numbers used to order sets of Units are given in the following table. One set comprises the Display (with built-in LED), and Socket Unit.
Appearance Degree of protection Model number Color symbol for Display Minimum packing unit
img IP40 M2DJ-90A1-00E□ R, Y, G, W 10 pcs
img M2DA-90A1-00E□
img M2DT-90A1-00E□
Note: 1. Enter the desired color symbol for the Display in □: R (red), Y (yellow), G (green), or W (white)
  2. Degree of protection: IP40

Ordering Individually
Displays and Socket Units can be ordered separately. Combinations that are not available as sets can be created using individual Units.
Ordering: Specify a model number from the following table.

Maximum value 2.2 V 2.4 V 2.5 V
Forward current, IF Reference value 20 mA 20 mA 20 mA
Absolute maximum value 50 mA 30 mA 30 mA
Permissible dissipation, PD Absolute maximum value 110 mW 72 mW 75 mW
Reverse voltage, VR Absolute maximum value 5 V 5 V 5 V
Note: 1. The above ratings are for an ambient temperature of 25°C.
  2. The built-in LED lamp has no limiting resistor and so it is necessary to connect an external resistor within the range shown in the above table. (For details of calculation formulas, refer to page 28.)
  3. Refer to the characteristic graph of VF - IF on page 24.
  4. The same LED lamp is used for both yellow illumination and white illumination and so the ratings are the same.

Ambient operating temperature –10°C to +55°C (with no icing or condensation)
Ambient operating humidity 35% to 85%
Ambient storage temperature –25°C to +65°C
