It is the shell half that carries the signal pins in a standard DB-25 (shell size 3, layout B) configuration. The shell is steel with tin plating, providing basic EMI shielding when mated with a corresponding D-sub receptacle housing. The dielectric is glass-filled nylon (polyamide). This housing is the plug half — it mates with any standard receptacle housing (female contacts) of the same series or compatible D-sub footprint.
You must order the male crimp terminals separately (TE part numbers 1-66506-0 or 66569-3 for standard 20-24 AWG signal contacts). This is the most common sourcing mistake: a buyer orders the housing expecting a complete connector and has to place a second order for the contacts. A removal tool (TE 91067-1) is needed to extract a mis-seated contact. The housing colour is black, supplied in bulk packaging. The shell finish is tin over steel — adequate for most indoor industrial and commercial environments. For corrosive or outdoor installations, consider a stainless steel or nickel-plated version from the same series.
This plug housing mates with any standard DB-25 receptacle housing (female contact side) of the AMPLIMITE HDP-20 series or compatible D-sub footprint. The unthreaded flange means the mating pair relies on the receptacle's threaded inserts or a separate screwlock kit (e.g., TE 5748273-1) for secure panel mounting. For free-hanging cable-to-cable applications, the latch lock on the shell provides basic retention. The 2-row layout follows the standard pinout — position 1 is in the upper row, rightmost when viewed from the pin side.
