| Feature | Benefit for OEM design |
|---|---|
| Product-specific configuration | Keeps selection aligned with Straight, Plug, 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 Straight, Plug, 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. |
M8 Waterproof 3P/4P Plug-in Straight Male/Female Connectors is used for M8 waterproof circular connector applications in compact sensor wiring, automation modules, machine control equipment, field signal connections. It should be selected according to the product drawing and mating interface.
Start with Straight, Plug, Male, Female, then confirm pin count, mounting style, cable exit direction and the final assembly space.
Check the product drawing, mating part, PCB footprint or cable route, orientation, quantity, packaging and any inspection document requirements.
Yes. Soulin can support drawing-based confirmation, connector option matching, cable assembly requirements, packaging and production documentation for OEM projects.
Confirm M8 pin count, male or female side, panel or cable mount style and cable route. For PCB-mounted products, also check pad layout, drill pattern, insertion direction and available clearance.
Common applications include compact sensor wiring, automation modules, machine control equipment, field signal connections. The final use should be verified against the electrical and mechanical drawing.
