It sits in the 1761185 series of right-angle jacks, sharing the same base footprint and shielding architecture. The keyed housing and integral board guide prevent mis-mating and simplify alignment during PCB assembly, which matters when the jack lives on a densely populated line card.
Mounting and Shielding — Fit for a Line Card
The single-row, 4-contact layout keeps the footprint narrow, and the board guide takes the insertion force off the solder joints during repeated plugging.
Tin-plated contacts would fret under vibration; the gold here avoids that failure mode in telecom cabinets where the jack stays mated for years.
Temperature Range and Housing
Rated for -20°C to 80°C operating range, the polyester housing keeps its dimensional stability across the typical indoor telecom temperature band. The housing carries a keyed feature — the plastic boss on the mating face ensures only the matching SDL plug engages, blocking a standard RJ-style plug that could short the wrong pins.
