M85049/38S-11N Straight Self-Locking Strain Relief Clamp for D38999 Series III / IV Connectors

The M85049/38S-11N is a straight cable clamp backshell designed for circular electrical connectors. It is the AS85049 / GJB1784 standard part number, interchangeable with J1784/38S-11N, and is commonly used with GJB599 / D38999 Series III and Series IV connectors in shell size 11.

As an /38S-type accessory, the M85049/38S-11N provides self-locking coupling and mechanical strain relief without EMI shielding braid termination. Tightening the cable clamp helps retain the cable body and reduce pull-out stress on solder or crimp terminations in vibration-prone installations.

Product Features

• Conformant to national standard GJB1784 (equivalent to AS85049)
• Interchangeable with cross-reference part number J1784/38S-11N
• Straight strain relief clamp for compact cable routing and mechanical retention
• Self-locking coupling (S) for improved vibration resistance during installation and service
• Suitable for Series III / IV connectors where cable clamping without EMI banding is required
• Electroless nickel plating finish denoted by the N suffix
• Shell size 11 for D38999 / GJB599 Series III and IV circular connector interfaces

Compatible Applications

The M85049/38S-11N straight strain relief clamp is intended for aerospace, avionics, and industrial platforms that use D38999 / GJB599 Series III / IV circular connectors and require straight cable exit with mechanical strain relief. Typical use cases include:

• Aircraft and helicopter wiring harnesses with limited rear clearance
• Avionics LRUs, radar, and communication equipment
• Ground vehicles and rugged electronic enclosures
• Shipboard and industrial connector assemblies
• High-vibration installs where self-locking coupling improves retention

Selection Guide

Installation Notes

• Confirm shell size 11, self-locking style (S), and finish (N) before ordering.
• If clamp screws are used, apply thread-locking compound before final torque.
• Where required by the harness drawing, add anti-loosening methods such as safety wire, thread-locking compound, or full heat-shrink over the accessory.
• Verify connector series compatibility: /38S accessories are intended for Series III / IV interfaces, not Series I / II clamp styles.
• Strain-relief-only clamps such as M85049/38S-11N are best suited to clean, dry applications; for full environmental sealing plus EMI protection, select a shielded environmental backshell.

Why Choose M85049/38S-11N

Form-Fit-Function Compatibility

Choosing the M85049/38S-11N ensures form-fit-function compatibility with J1784/38S-11N supply chains while meeting GJB1784 / AS85049 requirements. The straight self-locking clamp geometry simplifies harness routing behind Series III / IV circular connectors, reduces strain on solder or crimp terminations, and supports reliable operation in aerospace and industrial interconnect systems.

Ordering Information

Order by the AS85049 designation M85049/38S-11N, or cross-reference as J1784/38S-11N, depending on your procurement standard. When requesting a quote, please confirm mating connector part number, cable outer diameter, and required quantity.
