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. ■ Connectors Model XM3B XM3B-F XM2S Sockets with right-angle DIP terminals (with ferrite core) Hoods Appearance Sockets with right-angle DIP terminals Reference page 3 to 4 Model 5 XM3C 10 XM3F XM3A XM3D Plugs with solder-cup terminals Sockets with solder-cup terminals Appearance Plugs with right-angle DIP terSockets with straight DIP terminals minals Reference page 6 to 7 8 9 1 ■ Ratings and Characteristics Model Plugs with Solder Cup Terminals: XM3A Socket with right-angle DIP Terminals: XM3B Socket with right-angle DIP Terminals (with ferrite core): XM3B-F Plugs with Right-angle DIP Terminals: All XM3C models except those with 37 pins XM3C-0922-@@@ XM3C-1522-@@@ XM3C-2522-@@@ Sockets with Solder Cup Terminals: XM3D Sockets with Straight DIP Terminals: XM3F Item Rated current 5A Rated voltage 300 VAC Contact resistance 15 mΩ max.

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.
