Precautions

■ Correct Use

Grounding

To ground, create copper foil around the connector attachment hole on the

board, assemble the connector and grounding fixture, and dip in solder as

shown below.

Tap Hole Grounding Fixtures

Insert the connector into the PCB, tighten the screws, and then dip-solder the

connector terminals to the board.

Lock Pin Grounding Fixtures

Insert the connector into the PCB and then simultaneously dip-solder the con-

nector terminals and lock pin to the board.

Attaching the Dust Cover

To attach the cord to the connector, use Anchor 1 and secure it as shown

below.

To attach the cord to a panel, drill an M3 hole in the panel and secure the cord

to it with an M3 screw. If the cord is not required, cut it off. Use a commercially

available M3 screw.

Tightening Clamp Screws

Use the following torques when tightening cable clamp to hood.

Shielded Cable Preparation

Refer to the following diagram when soldering shielded cable to the connector

when using a hood.

1. Fold the unravelled braided shield back over the cable bushing

2. Wrap tape around the folded shield.

Shield Effects

When connecting the braided cable shield to a connector hood, use the cable

clamp to clamp all the braids at once through the shielded tape.

Mate the lock screw washer and spring washer outside the connector when

assembling the hood.

Keep the shell flange of the connector as far away from the metal panel as

possible to maximize the shield effect with a connector mounted to a panel.

The ground wire for the connector will fall into the shell (external metal cover-

ing) with solder-cup terminals, so connect the ground wire to the panel or to

ground on the board.

XM3A/XM3D Connector Insertion and Removal

Grasp the connector or the hood cover when inserting and removing the con-

nector. Never try to remove the connector by pulling the cable.
