Straight Strain Relief Clamp, Self-Lock, Shell 13 (C), 180° — AS85049/38

Specifications

Overview

The M85049/38S13N is an AS85049/38 straight strain relief cable clamp for MIL-DTL-38999 Series III and IV connectors, sized for a size 13 (C) shell. The /38 is the straight 180° backshell; the /39 is the 90° version of the same body.

The 'S' in the part number is the self-locking coupling variant, which grips the connector's coupling ring rather than spinning freely - the configuration that survives vibration without a separate safety wire. Finish N is electroless nickel over aluminium alloy, the correct pairing for class F (electroless nickel) and class G connectors; a class W connector should instead take a W (cadmium olive drab) backshell for the same 1,000-hour salt spray performance.

Strain relief is not cosmetic: an unsupported cable bundle transfers its load directly to the contact crimps and the insert. A correctly sized clamp - the dash number must match the connector shell size, e.g. a D38999/26WC35PN (shell 13) takes M85049/38-13 - is what keeps the termination inside the insert's mechanical envelope.
