What are the most common connectors used in industrial automation sensors?
The most widely used connectors are M8, M12, and M16 circular connectors. M8 is suited for compact sensors, M12 is the industry standard for sensor and fieldbus connections, and M16 offers higher pin counts and durability for more demanding industrial applications.
Why is the M16 Circular Connector suitable for industrial applications?
The M16 Circular Connector provides a secure threaded locking system, multiple pin configurations, and strong sealing options (IP67/IP68). These features make it ideal for harsh environments, such as robotics, automation machinery, and outdoor industrial control systems.
How does an M16 connector compare with M8 and M12 connectors?
Compared with M8 (smaller, fewer pins) and M12 (standardized, versatile), the M16 offers more pins (up to 12), higher current capacity, and superior durability. This makes M16 a better choice for applications requiring robust performance and higher-density wiring.
In which industries are M16 Circular Connectors commonly used?
M16 connectors are widely applied in robotics, automation machinery, control panels, transportation, and logistics systems. Their rugged design ensures reliable performance in environments with vibration, dust, and moisture.
