M12 B-Coded Male Rear Mount Socket, 5-Pin

Xmost M12 B-coded male rear mount socket provides an external threaded mating interface with wiring connections behind the panel. Its rear fastened mounting arrangement suits equipment housings designed for a rear mount receptacle.

This M12 B-coded panel mount connector offers five contacts, solder termination and a choice of unwired or pre-wired construction. Select the mounting thread and lead length to match the panel design and internal wiring layout. For PROFIBUS-related installations, check the complete assembly against the network’s wiring and shielding requirements.
