M8 waterproof 4-pin male and female connector set, featuring a dual knurled screw and nut design. The knurled threads provide a non-slip grip, making tightening smoother and ensuring a stronger locking force. This effectively prevents loosening and back-screwing in vibrating equipment environments. An integrated high-seal waterproof O-ring ensures an IP67 protection rating upon connection, providing effective dust and water resistance as well as oil resistance, making it suitable for outdoor and industrial environments with high humidity and dust. The gold-plated contacts offer excellent contact performance, stable conductivity, and strong interference resistance, withstanding extreme temperatures and repeated mating cycles. Simple overall assembly and convenient wiring, combined with a sturdy and durable housing, make these connectors widely used for waterproof and reliable circuit connections in industrial automation, precision sensors, and industrial control equipment.

| Feature | Benefit for OEM design |
|---|---|
| Product-specific configuration | Keeps selection aligned with Male, Female instead of mixing the item with nearby catalog variants. |
| M8 compact circular interface | Supports smaller field wiring points where connector size, cable route and mating side need to stay compact. |
| PCB or cable integration | Helps engineers plan the board footprint, cable direction and installation space before sample approval. |
| Mating interface planning | Encourages checking M8 pin count, male or female side, panel or cable mount style and cable route before releasing the BOM or PCB drawing. |
| Production-friendly sourcing | Supports repeat purchasing by confirming drawings, packaging, labels and inspection requirements. |
| OEM manufacturing support | Soulin can align connector options, cable assembly details and production documentation with project needs. |
| Selection point | What to confirm |
|---|---|
| Confirm the product configuration | Check Male, Female, part number and drawing revision before sample approval. |
| Match the mating side | Verify M8 pin count, male or female side, panel or cable mount style and cable route so the connector does not mismatch during assembly. |
| Review mechanical clearance | Confirm height, cable exit, latch operation and enclosure space in the final product. |
| Align production details | Define packaging, inspection documents, sample quantity and repeat-order requirements early. |
