The Molex 1731070065 is a D-Sub, Combo plug with male pins — a hybrid shell that packs 15 signal positions plus 2 coax or power positions into a single 17W2 layout. The shell size is 3 (DB, B), so it's wider than a standard DB-15 to accommodate the mixed contact arrangement. It mounts to a panel via unthreaded housing/shell flanges, and the contacts are terminated by solder cup — you wire it in, not crimp it.
The Hybrid Position Count — Why 17W2 Matters
The 17 positions break down as 15 signal contacts plus 2 coax or power contacts — that's the 17W2 layout code. The 17W2 insert is wider and keyed differently, so you cannot mate it with a standard DB-15 receptacle. The mating half must be a 17W2 receptacle, and the coax/power positions accept separate contacts (not included). The 5A current rating applies per contact.
Contacts Are Not Included — Plan Your BOM
This shell ships empty — the contact type is listed as "Signal and Coax or Power (Not Included)". You need to source the signal contacts and the coax or power contacts separately. The termination is solder cup, so you'll solder the wires directly into the cup on each contact. Gold finish on the contacts gives good corrosion resistance and mating cycle life for field-serviceable connections. Grounding indents on the shell provide early-mate shield continuity, which helps with EMI control in noisy industrial environments.
