MGG.4B.340.CLL 40-pin connector features a classic push-pull self-locking design with 40 high-density signal contacts. It has a rated current of 2–3A per contact, supports wide temperature operation, and provides excellent EMC shielding performance. With standard keying for anti-mismating, it supports solder cup, PCB, and other termination methods. MGG.4B.340.CLL offers long mechanical life, strong environmental resistance, and high vibration resistance, making it widely used in multi-channel signal connections for medical, industrial, and test equipment.
This connector series offers a well-balanced size with excellent space efficiency. It provides more contact pins than smaller connectors while occupying less space than larger models. With up to 40 contacts, it supports multi-channel signal transmission in a compact body, making it ideal for devices that require high signal density without excessive volume.
It adopts a reliable push-pull self-locking mechanism that enables quick mating and unmating. The connector locks automatically when plugged in and releases smoothly when pulled, ensuring efficient operation even in limited operating space. This stable locking structure prevents accidental disconnection caused by vibration or movement, ensuring continuous and safe connection.
The connector features excellent shielding performance, strong anti-vibration capability, and wide temperature resistance. It maintains stable electrical performance under harsh environmental conditions, including extreme temperatures, mechanical vibration, and electromagnetic interference. It is highly suitable for precision equipment in medical, industrial, and testing applications.
Designed with standard interface dimensions and anti-mismating keying, it ensures accurate and safe connection. It supports multiple termination methods such as solder cup and PCB mounting, providing flexible wiring solutions. Its standardized structure allows easy replacement and upgrade, widely adapting to various multi-channel connection requirements.
