Two new series of connector backshells from Weald

Weald Electronics’ LMA 69H1 backshells deliver secure strain relief to cables via an adjustable cable clamp. They are compatible with MIL-DTL-38999 Series III (Souriau 8D Series) connectors with rear accessory threads and can be specified with the same plating finishes. LMA 69H1 Series backshells metalwork is machined from solid material rather than cast, providing optimum levels of strength and in-service reliability.

While the connector interface includes an O-ring seal, this series of backshells does not provide additional environmental protection to the connector and cable and are designed to be used without heat shrink boots over the connector-to-cable transition. For EMC screen termination variants, the LMA19 Series is available, for ultra-low-profile style, consider the LMA67 Series and for heat shrink boot backshells select the LMA79 Series.

Key features include:

• Compatible with MIL-DTL-38999 / D38999 Series III and IV (H interface) circular connectors
• Provide secure strain-relief and cable support to prevent cable or connector damage due to bending or overloading at the rear of the connector
• Straight variants are available, please consult the factory regarding 90-degree versions
• Machined Aluminium metalwork for high strength and reliability
• Wide range of sizes and plating finishes available from stock

LMA 79 Series backshells facilitate the secure mounting of heatshrink boots over the connector-to-cable transition. They are compatible with MIL-DTL-38999 Series III (Souriau 8D Series) and IV or MIL-DTL-26482 Series I (Weald LMH Series) connectors and can be supplied with a variety of finishes and variants to match the connector they are being used on.

The connector interface includes an O-ring seal around the connector interface, while the use of a suitable lipped heatshrink boot which is locked in place via a groove provides additional mechanical and environmental protection of the cable. The compete assembly with boot, reduces the risk of damage due to bending and pulling of the cable and provides sealing against water and dirt ingress.

The two-part spin-coupling design allows for uncoupling for repair without removing the heatshrink boot.
