This is a rear-lock M12 panel connector, also with PG9 thread and A-coding, and it is mostly used for devices with insufficient internal space.

We can take a look at the rear part of the product. Only the PG9 thread part is inside the device, and there is also a rubber ring groove to ensure sealing. For the welding pin part, we just need to weld the cable and it can be used. Of course, before welding, you should put on heat-shrinkable tubing for insulation treatment. For the welding pin part, we adopt the brass plating gold process to ensure the stability of the connector's transmission.

The product has a total of 4 pins. If your requirement doesn't need a ground wire, then you can assign two pins for power connection and two pins for data transmission. If you have the need for a ground wire, then you can choose the 5-pin product.

Of course, before that, you have to determine one thing first. Whether the product you need is a male connector or a female connector, and whether there is signal interference in the using environment. There are many similar questions, and these are all the issues you need to consider. You can sort out your questions and then send an email to us, and we will give you a solution.
