D-Sub Receptacle for Panel-Mount and Cable Applications
The Amphenol NFD17E09SBFE1CA is a standard-density D-Sub receptacle with 9 female socket contacts arranged in two rows. It carries a 250VAC voltage rating and 3A per contact current rating — typical for signal-level interconnect in industrial control, data communication, and instrumentation harnesses where the D-Sub form factor provides a rugged, screw-locked connection. The mating-side flange carries female 4-40 screwlocks — the thread size that mates with the male 4-40 hex standoffs or jackscrews on the plug side. This hardware is non-negotiable for vibration-resistant panel or cable assemblies; the screwlock pulls the pair together and holds the contact interface under tension. Termination is through-hole solder — the contacts are copper alloy, and the vertical orientation places the solder tails straight through the board for a standard D-Sub footprint layout. The package is tray, which suits hand-loading or pick-and-place with a tray feeder.
The 4-40 screwlock on the receptacle side accepts the mating plug's 4-40 jackscrew or hex standoff. The 4-40 thread is the most common D-Sub hardware size. The tin-plated steel shell provides adequate EMI shielding for typical industrial environments.
