Card Edge Connector
Industrial, IT Datacom
Give your PCB a PCIe-style card interface the proven way with this 64-contact edge-card slot from CONSHARE. It mounts through-hole: two alignment posts set the connector square before soldering, the black glass-filled housing rides through wave solder without distorting, and gold-plated contacts grip the card edge from both sides. No latch, no housing branding — a clean slot built for backplanes, test fixtures, riser boards, and repair work.
The slot is cut for standard PCIe card edges — the 1.57 mm thickness used across add-in boards everywhere. Sixty-four contacts, 32 per side on a 1.00 mm pitch, deliver a full card interface in a footprint just under 40 mm long. Contact forces are balanced so a card seats with even pressure instead of racking toward one end.
The no-latch design is deliberate. Where cards are held by a bracket screw, a fixture clamp, or the enclosure itself, a latching slot only adds insertion effort and slows removal. Here the card is held by contact grip alone until your hardware takes over — exactly what serviceable systems and test rigs need when cards come back out on a schedule.
Surface-mount connectors save drilling, but edge-card slots take a beating: every card insertion levers against the slot. Solder tails running through the full board anchor the connector against that leverage far better than SMT pads ever will.
The two guide posts drop into their own drilled holes and keep the connector dead square through the solder wave — no skew, no float. They align without snap-locking, so if a board ever needs rework, the connector comes off without a destructive fight. Alignment during assembly, freedom during repair.
Tails land in two rows set 2.50 mm apart, drilled at 0.7 mm on a standard pattern. No custom drill features, no special press-fit tooling — the land pattern drops into ordinary PCB design flow and ordinary PCB fabrication quotes.
Gold sits on the mating zone where card fingers slide in: it resists wear, ignores oxidation, and keeps contact resistance low over years of service. Tin covers the solder tail, because tin wets solder faster and cheaper than gold ever will. A nickel layer beneath both blocks diffusion so the finish stack stays stable through soldering and aging.
Splitting the finish this way is how the connector delivers gold-grade mating reliability without gold-grade pricing. You pay for precious metal only where the card actually touches.
Contacts are stamped from 0.25 mm brass and tempered to hold spring force across the full 50-cycle rating. The housing is PA66 loaded with 30% glass fiber and rated UL-HB — stiff enough to survive production-line handling and dimensionally stable through solder heat, so the slot opening stays true.
Parameter | Value | Why it matters |
|---|---|---|
Contacts | 64 (32 per side, 1.00 mm pitch) | Full card interface in minimal board length |
Current per contact | 1.1 A min. | Group a few contacts and power rails run comfortably |
Contact resistance | 30 mΩ max. | Negligible drop at signal and modest power levels |
Insulation resistance | 1000 MΩ min. | Adjacent lines stay electrically clean |
Dielectric strength | 500 V DC, 1 min | Real margin over working voltages |
Insertion force | 1.15 N max per contact pair | Card seating stays controllable with all 64 engaged |
Retention force | 0.15 N min per contact pair | Every finger stays gripped — no slack contacts |
Mating cycles | 50 | Sized honestly for test, service, and upgrade duty |
That 50-cycle figure deserves a straight answer: this slot is built for boards where cards get seated in production, reseated in test, and occasionally swapped in the field. It is not rated for daily hot-plug abuse. For fixtures with heavy reseating, pick a thicker gold option below and treat the slot as a scheduled wear item.
Contact plating comes in five levels, and the right pick depends on environment and duty cycle more than anything else.
Code | Gold in contact area | Best fit |
|---|---|---|
A | Flash gold | Cost-driven builds in clean, dry environments |
B | 3 µ" min. | General-purpose workhorse for standard service life |
C | 5 µ" min. | Longer field life with occasional reseating |
D | 10 µ" min. | Humid or mildly corrosive sites, busy test fixtures |
E | 15 µ" min. | Maximum corrosion margin, longest service |
Every option shares the same 80 µ" minimum tin on the solder tails and nickel underplate across the contact. Not sure which level fits? Tell CONSHARE the operating environment and how often cards get handled — plating upgrades cost little at ordering and a lot in the field.
Industrial backplanes and custom motherboards. Boards that host PCIe-style expansion but answer to no ATX spec. Through-hole mounting absorbs the insertion leverage that industrial handling deals out.
Test and burn-in fixtures. Cards moving between stations all day. The no-latch slot cuts teardown time, and the contact system holds calibration across the rated cycles.
Riser and adapter designs. Compact boards translating one card interface to another. The 2.50 mm tail row works in dense two-layer layouts without exotic drilling.
Board repair and replacement. Maintenance teams replacing damaged slots on legacy boards, where a drop-in fit matters more than a discontinued original brand.
Brass strip and resin lots are inspected on arrival. In production, stamping dimensions and plating thickness are monitored in process. Finished connectors undergo sampled electrical testing — contact resistance, insulation resistance, dielectric withstand — alongside dimensional checks and insertion/withdrawal force verification before anything ships.
Tube, tray, or box options keep solder tails straight and contacts clean through freight and incoming inspection.

Housing color: black or white
Branding: ships with an unmarked housing — ready for boards carrying your own name
Standard configurations run on rolling production schedules, so sample quantities aren't stuck behind tooling queues. Send your card layout and annual volume for a quote with real dates.
Yes. The opening matches the standard 1.57 mm card edge thickness, with 64 contacts — 32 per side — on a 1.00 mm pitch.
For production test and burn-in duty, yes, within the rating. If reseating is truly nonstop, order code D or E plating and put the slot on a scheduled replacement list like any other wear part.
0.7 mm holes on the standard tail pattern plus the two post locations. The recommended footprint drops straight into common CAD libraries.
Yes. A halogen-free variant can be specified at ordering if your application requires it.
No — it ships unmarked, which suits integrators building under their own brand. White housings are available if the board calls for a lighter aesthetic.
