The Amphenol AHDMBS-24-001 is a size 24 backshell from the DuraMate™ AHDM series, designed to terminate the cable end of an AHDM circular connector assembly. It provides strain relief and cable management for the wire bundle exiting the back of the connector, with a 180° straight cable exit that keeps the cable running in line with the connector axis. The M38x1.5 thread size matches the coupling nut on the corresponding AHDM size 24 plug or receptacle body — this is the mechanical fit that locks the backshell onto the connector. The housing is molded from black thermoplastic, giving it a lightweight, corrosion-resistant body suited for industrial and heavy-equipment environments where the DuraMate series is commonly deployed. The 1.622" (41.20mm) outside diameter and 1.126" (28.60mm) cable opening tell you the maximum cable bundle that can pass through — a 28.6 mm bundle diameter is the practical limit before you need a larger shell size. A built-in tie wrap holder on the backshell body lets you cinch the cable bundle to the backshell with a standard cable tie, preventing the wire weight from pulling on the connector contacts. This is a field-friendly feature — you don't need a separate clamp or boot, just a tie wrap and a few seconds on the harness bench.
Thread Fit and Cable Clearance — Sizing It Right
The M38x1.5 thread is the single most important dimension for fit — it tells you this backshell screws onto any AHDM size 24 connector body with the same thread pitch. The 1.126" (28.60mm) cable opening is the inside diameter of the cable entry; if your harness bundle is larger than 28.6 mm in diameter, you need to step up to a larger shell size or use a different cable entry method. The 180° cable exit means the cable runs straight out the back — no right-angle bend, so plan for the cable routing length behind the connector panel. This backshell is unshielded, so it provides mechanical strain relief but no EMI/RFI protection. If your application requires shielding continuity through the backshell, you would need a shielded variant in the AHDM series — this one passes the cable shield through to the connector body only if you add your own foil or braid termination.
Lifecycle and Sourcing — Active Production, No Obsolescence Worry
ROHS3 compliance is confirmed, so it meets the current European restriction on hazardous substances. The thermoplastic housing is standard for industrial equipment inside an enclosure.
Installing this backshell is a straightforward field operation: slide the backshell over the cable bundle before terminating the connector contacts, then screw it onto the AHDM connector body after the contacts are seated. The M38x1.5 thread is a fine-pitch metric thread — hand-tighten it snug, no wrench needed unless the application specifies a torque value. Once the backshell is threaded on, run a cable tie through the tie wrap holder and cinch it around the cable bundle to lock the cable in place. The 1.126" (28.60mm) cable opening means you need to prepare the cable jacket or braid to fit through that diameter — if you are using a thick-jacketed cable or multiple conductors, measure the bundle OD before committing to this shell size. The backshell ships in a box, not on a reel, so it arrives as a single piece ready for installation.
