RJ-45 modular jack prevents mismating to RJ-11 plug
28 March 2001
Interconnection
Eliminating the insertion and mismating of an RJ-11 (6-circuit) plug into an RJ-45 (8-circuit) modular jack is a concern for many telecommunication, networking and computer manufacturers. For example, PC manufacturers have frequent calls from customers who do not realise they are inserting a typical RJ-11 phone line plug into an RJ-45 Ethernet modular jack port. This mismating not only causes the user frustration since the intended connection is not made, but the modular jack can be damaged by the insertion of the wrong size plug.
Molex has designed an RJ-45 modular jack with an RJ-11 plug keep out feature that prevents mismating. This unique design incorporates an integrally moulded lever inside the modular jack that blocks the insertion of an RJ-11 plug to fully mate with the modular jack. The lever does not interfere with an RJ-45 plug, however. When an RJ-45 plug is inserted into the RJ-45 modular jack, the keep out lever moves out of the way, allowing the plug to fully mate with the modular jack.
This design is incorporated into the Molex inverted modular jack that meets Category 5 for Fast Ethernet. The top latch feature on the modular jack provides easy access to the plug latch during unmating. The modular jack is offered in both unshielded and shielded configurations.
