The clear/gray polycarbonate housing carries a keying feature to prevent mis-mating. This is a signal-level connector rated 1.5 A per circuit at 30 V, not a power interconnect.
This plug terminates to 24 AWG ribbon cable via crimp contacts. The keyed housing ensures correct orientation during mating. For crimping, TE recommends their SDL-specific hand tool or a semi-automatic press with the appropriate applicator; the terminal design requires a clean, full-crimp to achieve the rated retention.
The 1.5 A per-contact rating at 30 V is typical for signal-level SDL interconnects — think data lines, not power feeds. The 24 AWG ribbon cable is a standard gauge for this series; if your harness uses 22 AWG or 26 AWG, the crimp terminal may not be compatible. The shielded construction adds a ground path around the signal bundle, which is necessary in electrically noisy environments or where radiated emissions must be contained.
