Panel-Mount Shielded Receptacle, 24-Position Right-Angle Solder
The TE Connectivity 5553811-3 is a 24-position, shielded receptacle from the CHAMP.085 series. It terminates via solder to a through-hole PCB and mounts to a panel cutout using the integral 4-40 threaded flange — the same hole pattern as a standard D-sub shell. The outer shroud contact style means the signal contacts are recessed inside the metal shell, protected from physical damage during handling and mating. The shielded shell is the defining feature here. It provides a continuous ground path from the cable braid through the connector body to the panel, containing radiated emissions from the signal lines and protecting them from external interference. This makes the 5553811-3 a fit for I/O in industrial controllers, test equipment, or instrumentation where unshielded CHAMP connectors would let noise couple into the cable.
The 4-40 threaded flange accepts standard jackscrews or slide-lock hardware, so the mated pair stays engaged under vibration — no secondary latch required. The panel cutout follows the D-sub footprint, which means it retrofits into existing punched openings without a new tool. The solder termination is through-hole, not press-fit. That means the receptacle is soldered into the PCB during wave or hand-solder assembly, giving a mechanical anchor that the solder joints alone carry.
