The TE Connectivity AMPLIMITE HDP-22 1658682-1 is a 26-position, 3-row D-Sub high-density receptacle housing for female crimp contacts. It is a free-hanging (in-line) shell — no PCB footprint, no solder joints — designed for cable-to-cable or cable-to-panel harness assemblies where the contacts are terminated to discrete wires and loaded into the housing. The shell uses the DA (2) high-density layout, which packs 26 signal contacts into the same panel cutout that a standard DA-15 uses, giving you more circuits per inch of panel space. The housing itself is a glass-filled nylon shell with a tin-plated steel outer shield; the 200 µin tin plating on the steel shell provides corrosion resistance for industrial cabinet or equipment-room environments without the cost of a nickel finish. The unthreaded flange means it mates with a plug that has its own threaded inserts or a slide-lock system — no integral jackscrew on this side.
You must order the mating female crimp terminals separately from the AMPLIMITE HDP-22 terminal family. This is standard practice for D-Sub high-density housings: the shell and the contacts are line items on the BOM, not a single assembly. If you are filling a 26-position harness, budget for 26 female contacts plus spares. The housing accepts the standard HDP-22 crimp contacts, which are available in tin or gold plating depending on your mating-cycle and corrosion requirements.
