WEALD ELECTRONICS LMA19 series 90⁰ Backshells have been designed for use with D38999 connectors.  Devices allow for a more compact bend than a conventional 90⁰ heat shrink boot while still providing good mechanical protection and EMC performance. A common use is for cable plugs that are connecting to the front of equipment as the compact dimensions allow the cable to be kept away from the equipment while in use. When used in this manner the same teeth that mesh with the teeth on the back of D38999 connectors allow the angle to be set or ‘clocked’ in a convenient position helping to direct the cable away in exactly the desired direction. The sealing and strain relief backshells are manufactured in the UK and have been designed for MIL-DTL-26482 Series 1 and MIL-DTL-38999 (D38999) Series III and IV connector systems. Devices protect the cable and the integrity of the overall connection. They eliminate cable bending and over flexing and when used with a heat shrink boot, they prevent the ingress of liquids and dirt.
