It provides strain relief and cable management for round cable assemblies with a 180° straight cable exit. The black ABS plastic housing includes assembly hardware and grommets, plus the 4-40 mating screws needed to secure it to the D-Sub connector. This is an unshielded backshell — for shielded cable runs, you would need a metal-shell variant from the same series. ## Fitting the Backshell to Your D-Sub The backshell is compatible with standard D-Sub 25-position connectors (DB-25 size) and also with high-density 44-position connectors that share the same shell size B. The included 4-40 mating screws are the standard thread for D-Sub backshell attachment; they thread into the D-Sub connector's screw-lock inserts. The assembly hardware and grommets are in the bag, so no separate fastener order is needed for a single unit. The housing is molded from ABS (Acrylonitrile Butadiene Styrene), a standard thermoplastic for backshells that offers good impact resistance and dimensional stability. The part is ROHS3 compliant, which covers the full RoHS directive including phthalates — acceptable for equipment sold into EU markets. No UL or VDE rating is listed on this entry, so if your application requires a specific flame rating, check the full datasheet for the plastic grade.","metaTitle":"TE Connectivity 5748678-3, AMPLIMITE Backshell, 25 Pos, 180°","metaDescription":"5748678-3 TE Connectivity AMPLIMITE two-piece backshell, 25 positions, 180° cable exit, black ABS, includes 4-40 mating screws.
