What This Clamp Fits and What It Carries
The TE Connectivity Deutsch 0409-201-1800 is a tin-plated, silver cable clamp from the HD30 series, shell size 18. It's the piece that cinches down on the cable jacket at the back of a Deutsch HD30 connector, taking the strain off the contacts and sealing the cable entry. The 1 3/16-18 UNEF thread mates with the matching backshell or connector body, and the 0.760" (19.30 mm) cable opening handles a specific cable diameter range — measure your cable jacket before ordering, because if it's too fat or too skinny the clamp won't seat properly. It ships with the bushing and clamp screws included, so you're not hunting for hardware mid-install. The 180° cable exit means the cable runs straight out the back — no right-angle routing. Unshielded, so it's a mechanical strain relief, not a grounding clamp.
Thread and Cable Fit — What to Check Before You Order
The thread is 1 3/16-18 UNEF — that's a UNEF (Unified Extra Fine) thread, not a standard UNF or UNC. If your mating backshell or connector body has a different thread pitch, this clamp won't thread on. The cable opening is 0.760" (19.30 mm), and the outside diameter of the clamp body is 1.469" (37.31 mm) — that outside diameter matters if you're routing through a tight panel cutout or boot.
