The M8 welded circular metal connector is specially designed for industrial equipment connection. It uses a brass pin core with a nickel-plated shell, which has both conductive properties and corrosion resistance. The screw locking structure ensures a stable connection, and the assembly welding process improves installation efficiency. It provides a variety of specifications of 3-8 pins to adapt to the signal/power transmission requirements of different scenarios. The compact size (body diameter 12mm) meets the installation in a small space. It is a reliable choice for automation and equipment control.
1. Product Features
Material and structural advantages: The main body adopts brass needle core, which is highly conductive, wear-resistant and durable; the shell is nickel-plated, with strong corrosion resistance, and is suitable for humid, dusty and other industrial environments. The screw locking design prevents vibration loosening and ensures long-term stable connection; the assembly welding process simplifies the installation process and improves production efficiency.
Performance reliability: The round metal shell provides 360° shielding protection and reduces electromagnetic interference; the precision-machined threaded interface (M8×1.0) is compatible with standard accessories and has strong adaptability.
2. Product size and number of needle cores
Main body size:
Diameter 12.0mm, suitable for M8×1.0 thread;
The standard length is about 42mm (tail φ5.5mm), and the compact length is about 40.5mm, which meets the requirements of different installation spaces;
The outer diameter of the installation thread section is φ6.9mm, which is convenient for fixing the bracket.
Number of pins configuration: 3/4/5/6/8 pins are available (including A/B/D types), male/female pins are arranged according to the standard (such as A-type 3-pin contacts are numbered 1-3, B-type 5-pin contacts are designed with center symmetry), supporting mixed transmission of signals and power, and flexible adaptation to various scenarios.
