The MS27508E12B4P is a 4-pin MIL-DTL-38999 Series III circular plug connector specifically engineered for marine and shipboard electrical systems where reliability, durability, and compact design are critical.

Built with a rugged aluminum alloy shell and IP67-rated sealing, it offers protection against salt spray, water ingress, and dust, making it ideal for harsh onboard environments. The connector’s bayonet quick-lock coupling ensures secure mating even under constant vibration and mechanical stress typical of engine rooms, deck machinery, and automation panels.
Connectors
Ideal for Critical Marine Applications

Bridge & Navigation Systems: Reliable signal paths for radar modules, GPS units, and electronic chart display systems.

Engine Room Monitoring: Secure connections for temperature sensors, oil pressure modules, and generator feedback circuits.

Deck Machinery Controls: Robust interface for winch, crane, and hatch control wiring exposed to saltwater and mechanical stress.

Automation & Control Panels: Compact solution for PLCs, distributed I/O systems, and sensor networks on ships.

Circular Connectors


Electrical and Mechanical Reliability

4-pin configuration supports low-current power and signal circuits.

Crimp termination provides consistent electrical contact and minimal resistance.

Wide temperature operation from −65°C to +200°C ensures performance in extreme conditions.

Vibration and shock-resistant design keeps connections stable in high-stress marine environments.

The MS27508E12B4P is a compact, high-performance connector that combines marine-grade corrosion resistance, precise electrical integrity, and mechanical robustness, making it an essential component for shipboard, offshore, and industrial control systems where failure is not an option.
