Description
⚓ Bottom Line Up Front (BLUF)
The ONWA M12 5-Pin Field Assembly Connector allows marine electricians, technicians, and vessel engineers to construct custom-length NMEA 2000 cables or re-terminate cables routed through narrow bulkheads and cable conduits without soldering. Featuring precision internal screw-clamp terminals, gold-plated contacts, and a compression cable gland providing an IP67/IP68 waterproof seal, it simplifies on-board refits and repairs. Available in male and female versions from Seanav Marine, Dubai Maritime City.

Frequently Asked Questions (FAQ) – Expert Insights
Q: Does the ONWA M12 field connector require soldering?
A: No. It uses precision internal screw-clamp terminals that secure stripped wire ends securely using a miniature jeweler’s screwdriver, requiring no soldering iron on board.
Q: What cable outer diameters does the compression gland accept?
A: The heavy-duty rubber compression gland seals cables with outer diameters ranging from 4.0mm to 8.0mm.
Q: What is the standard NMEA 2000 wire color coding for this connector?
A: Pin 1: Shield (Bare), Pin 2: NET-S / V+ (Red), Pin 3: NET-C / V- (Black), Pin 4: NET-H / CAN-H (White), Pin 5: NET-L / CAN-L (Blue).
Q: Is the assembled connector waterproof?
A: Yes. When properly tightened, the compression gland and internal O-rings provide an IP67/IP68 immersion seal resistant to engine room oils and salt spray.
Q: Can this connector be reused if cable routing changes?
A: Yes. The connector can be disassembled, unscrewed, and re-terminated multiple times without degrading electrical performance.
Q: Where can marine technicians purchase field connectors in the UAE?
A: Seanav Marine supplies male and female field assembly connectors directly from our Dubai Maritime City counter.
