Versatile and rugged LMH circular connectors with a wide range of accessories

The LMH Range circular connectors from Weald Electronics are MIL-DTL-26482 Series 1 derived miniature bayonet locking connectors manufactured to satisfy the requirements of BS9522 F0017, BS/CECC 75201-003 and MIL-DTL-26482 defence specification. This fully compliant COTS connector delivers added features such as PCB contacts, plating options and EMC grounding-fingers, while optional coarse ribbed coupling nuts on free connectors allow operation when using protective clothing. The comprehensive series suits applications such as industrial equipment, factory automation, communications systems, tactical vehicles and defence systems.

Connector shells are manufactured from aluminium alloy and are obtainable in various highly corrosion-resistant plating finishes, including ROHS compliant versions. Inserts are of polychloroprene, compounded to a WEALD specification. Operating temperature range is -55C to +125C. The connectors have gold-plated, non-removable, solder or PCB type contacts.

To avoid mis-mating with similar connectors which when adjacently mounted, the connectors may be polarised by varying the insert positions within the shell, providing up to four additional orientations other than Normal (N), designated W, X, Y, Z. Also, up to four different shell keyways can be specified other than normal (N), designated B, C, E and F, where the insert orientation will be in the Normal (N) position.

To satisfy EMC and EMP requirements, free shells can be fitted with grounding fingers, and fixed shells can be fitted with accessories for screened cable termination. The standard range of accessories feature endbell adaptors, standard and long-length cable clamps, J-sealing glands and metal protective caps. The company also manufactures compatible backshells and accessories to further compliment the connector series, such as the LMA19D backshell, which provides 360° screen termination and heat shrink boot sealing and its LMD7000 series of metal dust caps, which can be specified and quickly assembled with a multitude of lanyard styles.

This extremely versatile LMH connector series can be supplied in nine shell sizes and 25 shell styles and offers very cost-effective performance for the number of possible connection pins.
