Isodyne’s revolutionary MIL-spec strain relief connector backshell solutions are at the forefront of connector technology, offering unparalleled benefits to engineers who demand nothing less than the best.

isodyne backshell

Our proprietary Isodyne Tool-less Braid Termination System sets a new standard in backshell installation and maintenance while providing environmental protection for EMI/RFI, HIRF, and lightning. Developed with meticulous attention to detail, this system ensures both individual shields and the overbraid are terminated at the backshell with a single band. The hallmark of our design is ease of use – with no tools required for the connector installation or removal of the spring band, allowing for prompt cable assembly re-entry for repair or re-pinning without compromising spring force.

Features of Our Strain Relief Backshell Connectors

Since 1990, the Isodyne backshell system has been the backbone of critical applications across land, sea, air, and space platforms that require maxiumum connector backshell performance:

Direct Connectivity: Our EMI/RFI banding backshells feature a spring band that ensure individual wires make direct contact with the backshell body, optimizing connectivity.

No Tools Assembly & Removal: Bid farewell to tools in the field. Our system facilitates the easy assembly and disassembly of the overbraid to the backshell, making modifications and repairs effortless.

MIL-Spec Design: With a tensile pull strength of 125 ft/lbs, which nearly doubles when a heat shrink boot is added, our MIL-spec backshells stand up to high vibration in harsh environments. The stainless steel spring band can be installed and removed thousands of times with no degradation in holding force, ensuring long-lasting performance.

Improved EMI Performance: The constant force spring band enhances holding force and reduces resistance under vibration, elevating your electromagnetic interference shielding to new heights.

Simplified Installation: Our innovative solution eliminates the need for solder sleeves and the calibration of crimp banding tools, streamlining the installation process while reducing component count.
