M12 4 Pin A-Coded IP67 Connector - Compact and Reliable Industrial Interface
The M12 4 Pin A-Coded IP67 Connector is designed for industrial and automation systems that require compact design, high reliability, and robust environmental protection. Its A-coded standard ensures compatibility with a wide range of industrial devices, while the IP67 rating provides full protection against dust ingress and temporary water immersion.
Connector
Unlike generic M12 connectors, this model combines precision engineering, durable housing, and flexible connectivity, making it ideal for sensors, actuators, control panels, and compact automation modules.

Engineered for Compact Industrial Applications
Industrial devices often operate in tight spaces, requiring connectors that are small yet highly functional. This M12 connector addresses these challenges by:
Providing a low-profile, space-saving interface
Ensuring stable electrical contact under vibration and mechanical stress
Maintaining consistent signal and power transmission in demanding conditions

Allowing straightforward installation and replacement in confined spaces

Connector

Its 4-pin configuration is ideal for basic power and signal connections in automation and industrial electronics.

Key Product Features
