The Amphenol AHDPBS-10L017-2405 is a size 24 backshell from the DuraMate™ AHDP series, designed to terminate the cable end of an AHDP series connector that carries the WTA modification. It is a straight 180° cable exit backshell in black thermoplastic, unshielded, and assembled via a snap-on mechanism — no tools required for attachment. The backshell is specified for sealed harness applications where the mated connector assembly must maintain an IP68 rating against dust and prolonged immersion. The 1.843" outside diameter and 1.476" cable opening give the clearance needed for a 37.50 mm cable bundle to pass through the rear of the connector.
IP68 and the Sealed Harness Context
The IP68 rating — Dust Tight, Waterproof — is the defining spec for this backshell. It means the mated connector assembly, with this backshell installed, can be submerged beyond 1 meter depth without water ingress. That rating is only maintained when the backshell is correctly snapped onto the connector body and the cable gland or potting is properly sealed at the cable exit. For an outdoor, washdown, or below-deck harness, this backshell is the piece that keeps the connection dry.
Cable Opening and Bundle Fit
The 1.476" (37.50 mm) cable opening sets the maximum cable bundle diameter that can pass through the backshell. This is a hard limit — if your cable jacket or bundle exceeds 37.50 mm, this backshell will not fit. For the harness builder, the opening is generous enough to accommodate a multi-conductor power or signal cable with a heavy jacket, typical of the industrial and off-highway applications the DuraMate series targets.
Mating Compatibility — Not a Generic Size 24 Shell
This backshell is listed for use with AHDP Series connectors that carry a WTA modification. That is a specific variant — not every size 24 DuraMate connector accepts this backshell. The shell size 24 marking refers to the connector interface size, but the snap-on feature and the WTA modification requirement mean you cannot assume it fits a generic size 24 circular connector from another series. Match the exact connector part number against the compatibility list before ordering.
