M2D Indicator
Cylindrical 8-dia. Indicator
- Same basic design as the A3D Pushbutton Switch.
- Good illumination with even surface brightness.
- Cylindrical body means panel cutouts can be made
easily.

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. |
