Modular connector (industrial connector)

Modular connectors, also known as industrial connectors or pin-and-sleeve connectors, are designed for reliable power distribution and signal transmission in harsh environments. These components typically feature multiple poles (e.g., 3P, 4P, 5P) with rated currents from 16A to 125A and voltage ratings up to 690V AC. They offer IP44 to IP67 prot...

Modular connectors, also known as industrial connectors or pin-and-sleeve connectors, are designed for reliable power distribution and signal transmission in harsh environments. These components typically feature multiple poles (e.g., 3P, 4P, 5P) with rated currents from 16A to 125A and voltage ratings up to 690V AC. They offer IP44 to IP67 protection ratings, ensuring dust and water ingress resistance. Modular connectors are available in various mounting styles, including panel mount, surface mount, and cable mount, with screw or crimp termination options. They often include mechanical keying and color-coding for safety and misconnection prevention.

These connectors are widely used in industrial automation, machinery building, power distribution systems, and renewable energy installations. Common applications include connecting motors, sensors, actuators, and control panels in factories, process plants, and outdoor installations. They are also essential in temporary power distribution for construction sites, events, and mining operations, where robust and quick-connect solutions are required.

Key subcategories include rectangular connectors, circular connectors, and heavy-duty connectors. Popular article codes follow patterns like HDC-HE-16M (heavy-duty connector, 16 poles, male), HDC-HA-4P (4-pole rectangular connector), and CM-4P-32A (circular connector, 4 poles, 32A). These codes typically indicate connector type, pole count, current rating, and gender. Other common series include Han® connectors, B-Series, and M-Series modular systems.

At Electric Automation Network, we provide real-time pricing, technical documentation, and express worldwide shipping for all modular connector needs. Our team of specialized engineers offers personalized support to help you select the right connector for your application, ensuring compatibility with existing systems and compliance with international standards like IEC 60309 and UL 1682.
