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.
