XM2/XM3
D-sub Connectors
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 supe-
rior 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)
■Terminology
zEMI
Abbreviation of ElectroMagnetic Interference (noise)
zMetallization
Here, metallization refers to plating over the plastic hood.
zShielded connector
Connector having a structure that can be grounded.
zBeating
A processing technique that ensures the contact amongst
the shells by beating a part of the shell.
zESD
Abbreviation of ElectroStatic Discharge
zGrounding structure
Here, grounding structure refers to a structure where an
unmetallized hood can be grounded by an grounding
plate.
zShell
Refers to the case covering the connector. Here, the shell
refers to the metal parts attached to the mating end.
