SMC VSS8-4-FG-S-3VZ Vacuum Switch Sensor Module

The SMC VSS8-4-FG-S-3VZ Vacuum Switch Sensor Module is a vacuum-sensing device from SMC that detects vacuum conditions and provides a switch signal to automation equipment. Identified by the part number VSS8-4-FG-S-3VZ, this module is used to verify vacuum presence within pneumatic systems and to feed feedback to controllers, PLCs, or other automation logic. In industrial environments, vacuum switch sensors like this one help ensure proper sequencing of vacuum-driven operations by confirming that a vacuum level is present before actuators engage. The compact form factor and exact model code facilitate straightforward identification for maintenance, ordering, and system integration within an automation setup that relies on reliable vacuum sensing. By using the VSS8-4-FG-S-3VZ, technicians can align installation and documentation with the specific SMC product lineage and minimize ambiguity during service or replacement.
