The Weald Electronics LMH range of bayonet coupling connectors is designed specifically to meet the requirements of MIL-DTL-26482 Series 1 as well as Patt 105 and is manufactured to IECQ-CECC spec BS/CECC 75201-003 and BS 9522 F0017. As a result, the connectors are suitable for a wide variety of military and demanding industrial applications including communications and test and measurement.

The Weald LMH range of multi-pin circular connectors can be supplied in nine shell sizes and 25 shell styles and standard connectors can be supplied with 2 to 61 contacts. LMH connector shells are manufactured from Aluminium Alloy and, as standard, they feature a high resistance to corrosion thanks to an olive drab chromate conversion over a Zinc Cobalt, RoHS compliant plating finish. Other finishes available include Cadmium, black Zinc Nickel and electroless Nickel.

An often-overlooked benefit of the Weald manufacture is the bonding of the solder contacts during assembly. This provides a through-connector seal even when unmated and each connector is leak-tested at 1 bar during final assembly.

Weald Electronics further supports the LMH range of standard circular connectors with a selection of accessories including panel sealing gaskets, backshells and protective caps manufactured to the same demanding standards.

There are also connectors designed specifically for power applications and versions that incorporate EMI suppression filters which reduce assembly time by eliminating the need for external filter components. Another version comes with PCB contacts which allows LMH connectors to be mounted directly on to printed circuit boards.

Power

LMH power connectors are available in 4 shell sizes and various styles with between 2 to 5 contacts in 6 contact arrangements. The connectors feature peak working voltages as high as 500V – DC or AC and maximum current ratings at 85⁰C range from 7.5A for size 20 to 45A for size 8 with 13A for size 16 and 23A for size 12.

EMI Filtering

The LMHF (for filter) connector system is designed for those applications that need EMI suppression. As standard, the LHMF version is supplied with filter capacitance values from 0.75 to 20nF. These are offered in fixed square flange or single hole mounting shell styles with PCB contacts designed for quick and easy assembly. Additional capacitance values and bespoke filtering configurations can also be provided.

Standard LMH and LMHF connectors are generally available from stock on a next day delivery basis with no minimum quantity or value requirement. Furthermore, as the connectorsare made in the UK, Weald is able to assemble LMH connector solutions to a customer’s exact specification on surprisingly short lead times.
