The 1-215882-0: It is the female half of a standard AMP-Latch interface, mating with the matching 0.100" pitch male header (typically from the AMP-Latch or similar 2.54 mm header family). The gray housing carries feed-through slots so multiple receptacles can be daisy-chained along a single ribbon cable, and the integral polarizing key prevents reverse insertion into the header. This connector is built for internal equipment wiring — think card-edge cable assemblies, drive interconnects, and panel-to-board harnesses where the IDC termination saves time over discrete crimp-and-stuff methods.
The wire gauge acceptance is 28 AWG stranded or 26-30 AWG solid, which covers the common ribbon cable sizes used in 0.100" pitch flat cable assemblies. A hand press or bench press tool (TE part number from the AMP-Latch tooling family) is required; the termination force is consistent across all 10 positions when the cable is aligned to the slot.
The female sockets carry 31.5 µ" (0.80 µm) gold over the contact finish.
The lifecycle status is Active — TE continues to manufacture this part, and there is no last-time-buy or obsolescence notice on record. The base product number is 215882, which covers the unkeyed variant; the full 1-215882-0 includes the polarizing key feature.
