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 25- and 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. 5.9 18.5 0.3 3.6 2.84 9.6 3.3 3.0 B Dimensions Mounting holes (t = 1.6 mm, bottom view) No. of contacts B±0.1 D±0.1 E±0.1 F±0.1 15.5 9.9 N-1 N 1 2 3.0 1±0.1 dia. 2.84±0.1 Two, 3.2±0.1 dia.
