37-Position Hinged Backshell for AMPLIMITE HD-20 D-Subs
The TE Connectivity 1-5207908-0 is a hinged backshell from the AMPLIMITE HD-20 series, designed to fit standard 37-position and high-density 62-position D-sub connectors with a shell size C. It accepts round cable and offers both 90° and 180° cable exit orientations, giving you flexibility in routing the cable bundle away from the connector. The black polypropylene (PP) body is unshielded, so this is a straight mechanical cover and strain-relief piece — not a shielded enclosure for EMI-sensitive lines.
Hardware That Saves a Second Sourcing Trip
This backshell ships with the assembly hardware and a strain relief included, plus 4-40 mating screws. The 4-40 screws are the standard thread for D-sub backshells — they thread into the mating D-sub connector's threaded inserts to lock the assembly together. The strain relief clamps onto the round cable jacket, so the cable's weight and any tugging get transferred to the backshell, not the solder or crimp contacts inside the D-sub. That matters in a panel or enclosure where the cable gets handled after installation.
Unshielded — Know When to Use It
The listing explicitly calls this backshell unshielded. That means it provides mechanical protection and strain relief but no Faraday cage around the D-sub's solder buckets or crimp barrels. If your application runs signals that need EMI shielding — say, near a motor drive or a switching power supply — you need a metal or metallized backshell. For a clean data or control signal in a grounded metal enclosure, the plastic unshielded version is often all you need, and it saves weight and cost.
