D-sub Connectors
XM2/XM3
D-sub Connectors Are Ideal for Office
Automation Interfacing.
■ Shielded against EMI.
■ Metallized plastic Hood (XM2S) provides excel-
lent noise protection.
■ A new line of multi-hole, ferrite-core Connectors
(XM3B-F) offers space-saving design and superior noise protection at high frequency.
■ Fitted in a rugged, compact metal shell.
■ Many kinds of standard Anchors and grounding
fixtures available.
■ The XM2/XM3 conform to UL standards (No.
E103202) (XM2S and some other models are not
included)
RoHS Compliant
■ Terminology
z EMI
z ESD
Abbreviation of ElectroMagnetic Interference (noise)
Abbreviation of ElectroStatic Discharge
z Metallization
z Grounding structure
Here, metallization refers to plating over the plastic hood.
Here, grounding structure refers to a structure where an
unmetallized hood can be grounded by an grounding
plate.
z Shielded connector
Connector having a structure that can be grounded.
z Beating
A processing technique that ensures the contact amongst
the shells by beating a part of the shell.
z Shell
Refers to the case covering the connector. Here, the shell
refers to the metal parts attached to the mating end.

Note: XM3B Sockets were manufactured in accordance
with JIS X 5101. Terminal pitches are a mixed arrangement of 2.77- and 2.74-mm contacts on 25and 37-contact models as specified in the JIS
standard. A pitch of 2.76 mm is recommended for
the mounting holes because of the more advanced
numerical control available today. This is sufficient
to avoid any problems.
