The Ultimate Guide to M12 90 Degree ConnectorShine Industry
What Is M12 90 Degree Connector ?
M12 90 degree connector is also called right angle M12 connector , it’s M12 connector that the mating interface and the cable direction have 90 degree angle, for right angle PCB M12 connector socket , the the solder surface and the mating interface have 90 degree angle.
As we can see from the above picture , the M12 90 degree connector could be overmolded right angle M12 connector , metal or plastic cable assembly right angle M12 connector , PCB right angle M12 connector socket.
Why need to use M12 90 degree connector ?
Compared with the M12 90 degree connector, the M12 straight connector is more widely used. Under what circumstances should the right angle M12 90 degree connector be used?
- The space is too small to install the M12 straight connector, or if the M12 straight connector is installed, it will cause excessive bending of the cable and reduce the reliability of the connector. In this situation, the M12 90 degree connector is much better choice.
- There will be many different cables in the automation system. If the wiring is not standardized, it will cause a waste of space and may even cause unnecessary wear and tear of the cables. M12 90 degree connector can help more reasonable wiring.
How many right angle M12 connectors are there?
Sorted by different classification methods, the 90 degree M12 connector has different types. According to the material of the plug, there are metal assembly M12 90 degree connector, plastic assembly M12 90 degree connector , according to the code, there are A coded right angle M12 connector , D coded right angle M12 connector , divided by plug and socket, there are 90 degree M12 connector plug, 90 degree M12 connector socket.
Overmoulded M12 90 degree connector plug
The molded M12 right angle connector is mainly composed of three parts: cable, insulator, and shell. The insulator integrates the male or female pins according to different coding standards through the injection molding process, and then welds the conductor of the cable to the end of the male/female pin. Finally, the cable and the insulator are overmolded by the injection molding process to achieve a high level of protection.
The advantages of overmolded M12 right angle connectors are that the production speed is fast, the efficiency is high, the operation can be automated, different shapes, different sizes, and the product size is accurate, suitable for mass production.
At a certain temperature, the completely molten plastic material is stirred by a screw, injected into the mold cavity with high pressure, and cooled and solidified to obtain a molded product.
The injection molding process of plastic parts mainly includes 6 stages such as clamping – filling – (gas-assisted, water-assisted) pressure holding – cooling – mold opening – demoulding.
The shell of the M12 90 degree connector is made of PA(which also called Nylon), which has good mechanical properties, heat resistance, wear resistance, chemical resistance and self-lubrication, and has a low coefficient of friction, a certain flame retardancy, and easy processing. It has been widely used in waterproof connector shells.
