- When selecting the J30J product, both the plug (receptacle) assembly and the locking assembly should be chosen simultaneously, as the locking assembly is an indispensable component of the connector. The wire clamp assembly is not a mandatory option, but its selection can be determined based on specific needs.
In addition, due to the fact that not all plug (socket) assemblies, locking components, and wire clamp assemblies can be arbitrarily combined and matched, as well as product characteristics, the following items should be noted before selecting J30J products: - The selection of wire clamp assemblies should be conducted according to the "Wire Clamp Assembly Family Tree" specifications. Additionally, plug (receptacle) assemblies equipped with wire clamps should not be paired with front-of-board mounting lock components (i.e., lock components with mounting screws suitable for front-of-board mounting, such as P, P8, P9, etc.), as the presence of the wire clamp will prevent the mounting board from being installed. If plug (receptacle) assemblies equipped with wire clamps are to be paired with rear-of-board mounting lock components (i.e., lock components with mounting screws suitable for rear-of-board mounting, such as PO, P3, P4, P11, etc.), the thickness of the board must be considered as "mounting board thickness + 0.7".
