Our 3.96 mm three‑row machined pin header is a high‑reliability board‑to‑board / board‑to‑cable interconnect purpose‑built for CNC machine tools, PLC systems and heavy‑duty industrial controllers. Unlike conventional stamped pin headers, it adopts full CNC machined solid contacts to deliver superior mechanical stability, low contact resistance and consistent performance under vibration, temperature cycling and repeated mating cycles. Three‑row layout maximizes I/O density within limited PCB footprint, handling mixed signal and low‑power circuits for factory automation equipment. Fully RoHS & REACH compliant, supports through‑hole DIP soldering for industrial‑grade assembly conditions.

|---|---|
| Housing / Insulator | High‑grade PA6T / PBT thermoplastic, UL94 V‑0 flame retardant; Black standard color Wayconn El... |
| Contact Base Material | High‑strength brass/copper alloy, precision CNC turning |
| Plating Base Layer | Nickel under‑plating (anti‑corrosion barrier) |
| Contact Surface Finish | Standard: Tin over Nickel; Option: Selective/full Gold plating for high‑vibration / long‑life applications |
| Retention Structure | Injection‑molded interlock, pins firmly locked inside housing to avoid pin‑loosening under shock & vibration |
Suitable for scenarios requiring high mechanical reliability, anti‑vibration, long service life and frequent field maintenance.
