It carries 9 positions in 2 rows, which puts it in the standard DE-9 (E) shell size, the layout used for RS-232 ports and many industrial sensor interfaces. Black shell with an unthreaded flange — the flange accepts a standard D-sub slide-lock or jack-screw kit for panel retention, but the holes are unthreaded, so you supply the hardware. Critical note on the listing: contacts are not included. For the AMPLIMITE HDP-20 series, the mating-side female contacts are typically part number 1-66506-0 (size 20, loose piece) or the reel-fed equivalent for automated crimp. The housing accepts standard D-sub size 20 crimp contacts (20-24 AWG range), so any TE or AMP size-20 stamped-and-formed contact that fits the HDP-20 cavity will work. ## 9-Position DE-9 — The Standard Industrial Interface The 9-position layout is the most common D-sub shell size after the 25-position DB-25. It matches the DE-9 footprint used on serial COM ports, VGA (though VGA is typically DE-15), and many PLC and motor-drive communication cables. The 2-row arrangement gives a 5+4 contact pattern — five on the top row, four on the bottom. The unthreaded flange means it pairs with a male housing that has threaded inserts, or you add a slide-lock kit (like TE 5747845-4) for vibration-resistant mating.","metaTitle":"TE AMPLIMITE HDP-20 747521-2, D-Sub Receptacle Housing","metaDescription":"TE Connectivity AMPLIMITE HDP-20 D-sub receptacle housing, 9 positions, 2 rows, free-hanging.
