Notes:

1. Spreader pad material: Diallyl Phthalate.

2. To specify an “M”, “M2” or “M3” spreader pad, refer to the mounting variants portion of the part number example

in the applicable datasheet.

3. Dimensions are in inches (mm).

4. Unless otherwise specified, tolerance is ± .010” (0.25).

5/. Add 25 mΩ to the contact resistance shown in the datasheet.

6/. Add .01 oz. (0.25 g) to the weight of the relay assembly shown in the datasheet.

7/. Add 50 mΩ to the contact resistance shown in the datasheet.

8/. Add 0.025 oz (0.71 g) to the weight of the relay assembly shown in the datasheet.

9/. M3 pad to be used only when the relay has a center pin (e.g. ER411M3-12A, 722XM3-26.)
