M12 connector-welding wire long shielded circular metal connector, with straight head design and screw locking structure, metal shell treated with brass nickel plating, with long shield shell to achieve IP68 protection level, effectively resist dust, water immersion and electromagnetic interference. The welding wire process is suitable for a variety of cables, suitable for harsh scenarios such as industrial automation and sensor connection, with both stability and signal stability.
1. Product Features
The connector is built to industrial standards, with a metal shell and brass nickel plating process, which is corrosion-resistant and wear-resistant, and can adapt to complex working conditions; the straight head design simplifies the installation process, and the screw locking structure ensures a stable connection to prevent vibration and loosening; the long shielding shell extends to the cable end to enhance the ability to resist electromagnetic interference. With the IP68 protection level, it can withstand deep water immersion and dust intrusion to ensure signal transmission reliability. The soldering wire interface supports customized cable length to meet the wiring requirements of different devices. The male and female pins are clearly configured and have strong compatibility. It is an ideal choice for connecting devices in harsh environments.
2. Product size and number of pins
Size: Two mainstream specifications are available, the male head is about 35.0mm long (corresponding to M12 * 1.0 thread, shielding shell extension section 8.0mm), and the female head body is about 33.6mm long (shielding shell extension section 7.6mm), both of which are suitable for standard M12 mounting holes, with an outer diameter of 14.0mm, and a wall thickness that takes into account both strength and lightness.
Number of pins: Covering 4-12 pins with flexible configuration, including type A (4/5/8/12 pins), type B (5 pins), type D (4 pins), male and female pins are arranged in a circular array (such as 4-pin male pin holes are 1-4 clockwise, and female pins are opposite), supporting high-density signal transmission to meet the functional expansion requirements of different devices.
