What this connector is
The Molex 65823-508 is a 30-position dual-row board-to-cable header in the Quickie series, operating at 0.100" (2.54 mm) pitch with right-angle through-hole termination. The connector carries gold or Gold GXT plated contacts at 30.0 µin (0.76 µm) thickness on the mating interface, built on a phosphor bronze alloy base, with a blue glass-filled polyester insulator rated UL94 V-0. Four-wall shrouding, an integral keying slot, latch lock/eject hooks, and a mounting flange make this a shrouded, mechanically keyed header designed for panel or board edge mating in industrial automation environments.
How it fits the board
The 0.100" (2.54 mm) dual-row pitch and 30-position count define a 15-circuit-per-row footprint with 0.100" row spacing — the standard 2.54 mm grid that mostEDA libraries carry as a drop-in. The 0.105" (2.67 mm) tail length and 0.305" (7.75 mm) insulation height give a right-angle profile that sits flush to the board edge for panel or mid-board cable entry. The mounting flange provides mechanical anchoring against vibration at the board surface, and the four-wall shroud keeps the mating face protected against debris in industrial enclosures.
What the plating means for the application
Gold or Gold GXT at 30.0 µin (0.76 µm) on the mating interface sits at the high end of what is standard for industrial signal and low-power duty — sufficient for the number of mating cycles this latch-lock design is meant to survive. The GXT variant adds a hard gold overlay that resists fretting wear better than pure soft gold, which matters if the connector sees field plug-unplug cycles rather than a single installation mate. For a purely permanent installation with minimal cycling, the standard gold finish is adequate; for any reconnection duty, the GXT option is the one to confirm with the distributor on RFQ.
