NVENT HOFFMAN S2MBC Base coupling
nVent HOFFMAN S2MBC is a die-cast aluminium SYSPEND 281-MAX base coupling for mounting an HMI enclosure directly to a horizontal surface with 300-degree rotation, lockable positioning, a safety stop and maintenance-free bearing.
Why Choose the nVent HOFFMAN S2MBC Base Coupling?
The nVent HOFFMAN S2MBC is a robust base coupling for the SYSPEND 281-MAX suspension system, designed to attach an HMI or control enclosure directly to a horizontal surface. It provides a secure mounting point while allowing the enclosure to rotate through 300 degrees for flexible positioning in industrial machinery and automation applications.
Manufactured from durable die-cast aluminium with a RAL 9005 black finish, the S2MBC is engineered for reliable operation in demanding industrial environments. An integrated safety stop helps control enclosure movement, while the maintenance-free bearing provides smooth rotation without requiring routine bearing maintenance.
With overall dimensions of approximately 130 mm high × 125 mm wide × 125 mm deep and a weight of approximately 2.13 kg, the S2MBC provides a substantial mounting solution for operator-interface installations. Installation instructions, gaskets and enclosure mounting hardware are included, while hardware for fixing the coupling itself to the horizontal mounting surface is supplied separately.
