The M12 connector series with A/B/D/X coding offers 8-pin copper male & female configurations in a round, waterproof IP67/IP68 package — a compact interconnect solution for power and data transmission in industrial automation, robotics and marine equipment. Below is the full specification of the series, followed by application guidance.

Key Specifications

Coding Options

• A-coded — general power and signal circuits for sensors and actuators
• B-coded — Profibus fieldbus applications
• D-coded — Industrial Ethernet up to 100 Mbit/s
• X-coded — Gigabit Ethernet and high-speed data transmission with 8-pin arrangement

Design Advantages

• Watertight reliability — IP67/IP68 sealing with threaded locking ring for washdown and immersion environments
• Stable electrical contact — gold-plated copper contacts resist corrosion and maintain low contact resistance
• Rugged construction — nickel-plated copper / zinc alloy shells endure vibration and mechanical stress
• Solder-pin termination — secure, low-resistance conductor attachment

Applications

Typical applications include factory automation I/O, servo systems and fieldbus networks, as well as marine electronics such as underwater cameras, sonar heads, navigation sensors and ROV tooling. For deeper immersion or higher voltage requirements, see our subsea connector and circular connector ranges.

OEM/ODM customization (pin count, cable exit, shell material, overmolding) is available. Contact MarineConn for drawings and samples.
