Even unmated, MIL-DTL-26482 connectors deliver environmental seal

To operate even in the most demanding environments, the LMH series bayonet locking circular connector systems have been designed for a range of applications across a wide range of industries. The Weald Electronics’ LMH series, available from Lane Electronics, meets the requirements of MIL-DTL-26482 Series 1. They are manufactured with bonded insulators and contacts that are 100 per cent pressure-tested during assembly and so can provide a reliable environmental seal even when unmated.

They are also claimed to cost-effectively combine price, size, weight, contact size, robustness and reliable quick-connect operation, according to the distributor.

The LMH series connectors can be used in defence equipment, industrial automation, test and measurement, high performance communications systems and instrumentation.

The connectors are available for signal and power applications with a maximum current rating up to 45A and a peak working voltage of 1,500V DC or AC. One version is designed specifically for those applications that need EMI suppression.

Equivalent to Amphenol’s 62GB connector system, Weald’s LMH series connectors are available in nine shell sizes and 25 shell styles with standard connectors supplied with two to 61 solder bucket contacts. A choice of PCB contacts may also be selected and crimp contacts may be specified on a number of layouts.

In addition to meeting the requirements of MIL-DTL-26482 Series 1, LMH connectors are manufactured to IECQ-CECC spec BS/CECC 75201-003 and BS 9522 F0017.

LMH connector shells are aluminium alloy as standard, with a choice of high corrosion resistance plating finishes including the popular RoHS compliant electroless nickel and black zinc nickel plating. Traditional olive drab and RoHS -compliant zinc cobalt finishes may be specified; for defence and other applications.

The LMH connectors for power applications are available in four shell sizes and various styles housing two to five contacts in six contact arrangements. To satisfy electromagnetic compatibility (EMC) and electromagnetic pulse (EMP) requirements, free shells can be fitted with grounding fingers. Fixed and free shells can be fitted with accessories for screened cable termination.

The LMH series LMHF version is designed for use where EMI suppression is required. Designed for easy assembly, the LMHF connector eliminates the need for extra components, coming as it does with its own internal filtering in fixed square flange or single hole mounting shell styles. This helps reduce the space envelope required for filtering; particularly beneficial when upgrading existing equipment and where the use of a single connector component can help simplify and reduce assembly times and weight.
