Connectors

Connectors are the backbone of any reliable electrical or automation installation, serving as the critical interface between cables, devices, and control systems. In industrial environments, these components must handle a wide range of electrical parameters, including rated currents from a few milliamperes up to several hundred amperes, voltage ratings from low signal levels up to 1000 V AC/DC, and varying numbers of poles (e.g., 2P, 3P, 4P, or multi-pin configurations). Connectors come in diverse forms such as circular connectors (e.g., M8, M12, M23), rectangular connectors (e.g., Han series), terminal blocks (screw, spring-cage, or push-in types), and industrial plug-and-socket systems. Key technical specifications include ingress protection (IP) ratings like IP65, IP67, or IP68 for harsh environments, contact resistance, insulation resistance, and material composition (e.g., brass contacts with gold or silver plating, polyamide or metal housings). Whether for power distribution, signal transmission, or data communication, connectors ensure secure, repeatable, and maintenance-friendly connections.

Connectors are deployed across a vast spectrum of industrial sectors and applications. In electrical distribution panels, they facilitate the termination and branching of power cables. In automation and control cabinets, connectors link sensors, actuators, PLCs, and fieldbus systems (e.g., PROFIBUS, PROFINET, EtherCAT). They are essential in machinery and equipment manufacturing, robotics, renewable energy systems (solar inverters, wind turbines), transportation (railways, automotive), and process industries (chemical, pharmaceutical, food and beverage). Connectors also play a vital role in building automation, HVAC systems, and lighting installations. Their versatility allows them to be used in both fixed and movable installations, with options for panel mounting, cable mounting, or free-hanging configurations.

Within our extensive catalog, connectors are organized into several key subcategories. These include circular connectors (e.g., M8 and M12 sensor/actuator connectors, M23 power connectors), rectangular industrial connectors (e.g., Han A, Han B, Han E, Han Q series from Harting), terminal blocks (e.g., feed-through, ground, fuse, and disconnect types from Phoenix Contact, Weidmüller, WAGO), and heavy-duty connectors (e.g., HDC series). Article codes often follow manufacturer-specific patterns; for example, Harting connectors may use codes like 09 30 000 9901 (Han B hood) or 09 20 000 6101 (Han E insert), while Phoenix Contact terminal blocks use codes like 3030161 (PT 2,5) or 3212543 (PTFIX 6). These codes typically encode series, size, number of poles, and contact type. We also stock specialized connectors for data and signal transmission, such as RJ45 industrial connectors, D-Sub connectors, and USB industrial connectors.
