Siemens 6AV6-671-5AE11-0AX0 Connectivity Box Plus

Siemens 6AV6-671-5AE11-0AX0 Connectivity Box Plus is the PN Plus variant of the SIMATIC connectivity box line, a compact junction enclosure intended for use with Mobile Panel systems such as the 177 and 277 series. In Siemens literature this model is identified as 6AV6-671-5AE11-0AX0 SIMATIC Box PN Plus, and older manuals describe it as a DP junction box for Mobile Panels 177/277 (MPI/PROFIBUS), underscoring its role as the interface between the handheld HMI and the network. The enclosure measures 230 mm long, 160 mm wide, and 75 mm high, and weighs approximately 0.7 kg, making it a compact housing suitable for mounting alongside the mobile panel or as part of a panel assembly. As a Plus variant, it is positioned for use with the Mobile Panel PN family, providing a rugged, dedicated interface that facilitates reliable connections for industrial environments where panel cabling and network links must be neatly organized and protected. Catalog entries and distributor listings consistently reference this part number as a PN Plus connectivity box, reinforcing its place in the Siemens SIMATIC HMI ecosystem as a specialized interface accessory rather than a standalone controller.
