Circular connectors for PCB mounting are the backbone of reliable signal and power transmission in modern industrial electronics. These components, often referred to as circular PCB connectors or board-mount circular connectors, are designed to provide a secure and robust interface between printed circuit boards and external cabling. Key technical parameters include pin count (ranging from 2 to over 30 poles), current rating (typically from 1A to 30A depending on contact size), voltage rating (up to 600V AC/DC), and insulation resistance. They are available in various shell sizes and locking mechanisms such as bayonet, threaded, or push-pull, ensuring vibration resistance and IP ratings from IP40 to IP68 for harsh environments. The mounting style is specifically for PCB through-hole or SMD soldering, with contact arrangements conforming to standards like IEC 61076-2.
These connectors are essential in sectors requiring high-density interconnections and rugged durability. Primary applications include industrial automation control cabinets, robotics, servo drives, sensor interfaces, and fieldbus systems. They are also widely used in medical devices, test and measurement equipment, and transportation electronics where space is constrained and reliability is critical. The PCB-mount design allows for direct integration into control boards, eliminating the need for intermediate wiring and reducing assembly time.
Within this category, you will find subcategories such as M8 and M12 circular PCB connectors, which are common in sensor and actuator networks, as well as larger series like the 7/8" or 1" connectors for power transmission. Key article codes often follow patterns like "PCB-M8-4P" for a 4-pin M8 connector or "PCB-M12-5P-B" for a 5-pin M12 with B-coding. Other examples include "PCB-7/8-3P" for a 3-pin 7/8" connector. These codes typically encode the connector series, pin count, and coding type (A, B, D, X, etc.) for Ethernet or power applications.
