3M LC Hot Melt (MM Duplex) Connector

3M Hot Melt (MM Duplex) Connector

The 6603-D Hot Melt LC is a multimode duplex connector designed for termination of 2.4 to 3.0 millimeter jacketed cable. A beige duplex yoke latch actuator, shrink tube strain relief, and two boots white and beige are included.

The only LC connector with hot melt adhesive. The LC connector offers all the advantages of the 3M hot melt technology, including fast installation, ease of termination, reliability, low insertion loss and very high yield.

These singlemode and multimode connectors meet Telcordia GR-326 and TIA 568B.3 requirements for both indoor and outdoor LAN applications. As with the 3M SC and FC hot melt connectors, there is no need for a syringe, applicator or mixing of epoxy with the LC connector. The LC connector may be used in temperatures as low as -40 degrees Celsius and as high as 100 degrees Celsius.
