Product Overview
Wire Pro, Inc. 143-012-01 is a card edge receptacle designed for printed circuit board interconnects. It features 12 gold-plated phosphor bronze contacts arranged in a single row on 0.156-inch (3.96 mm) center-to-center spacing. The body is molded from blue diallyl phthalate and includes integral end mounting flanges with clearance holes for chassis or panel installation. Terminations are solder eyelet lugs numbered 1 through 12, allowing direct point-to-point wiring.

Frequently Asked Questions
What board thickness fits this edge connector?
The connector card slot accepts printed circuit boards with a standard edge thickness between 0.054 inches and 0.070 inches (1.37 mm to 1.78 mm).
Are the contacts single-sided or dual readout?
This is a single-readout connector with 12 contact fingers along one side of the slot, each terminating in a numbered rear solder eyelet.
How does this compare to dual-row 24-position connectors with the same footprint?
While sharing the 0.156-inch pitch and mounting span of 12/24 position dual-readout shells, this single-readout variant mates exclusively with a single contact face on the inserted daughterboard, preventing accidental cross-contact on single-sided PCB designs.
The unmistakable blue diallyl body and honest solder eyelets from an era when edge connectors were built to outlive the gear they plugged into. Seat your card, wire your harness, and get the machine running again.
