This is a circular flange panel connector with a 4-pin male plug. The fixing method is rear locking, and the thread size is M12x1.0. The connection of the electrical circuit can be achieved only by plugging it into a 4-pin female socket. 

 It should be emphasized that the male and female plugs on the panel cannot be directly plugged in. Because the outer shell and the internal rubber core of the panel connector are inlaid together, and panel connectors basically have fool-proof insertion slots, so they cannot be locked by screwing. 

 At this time, you can choose molded or assembled connectors according to the usage scenario. Their screw nuts and rubber cores have a separate structure. If you are not sure about the distance between the two devices, you can choose the assembled connector. If you have determined the distance between the devices, you can choose the molded connector.
