The SIEMENS 3RG40300AA00 is a proximity detection switch rated for 10-65 VDC supply. This is a standard inductive proximity sensor from the Siemens 3RG4 family, used for non-contact detection of metal targets in industrial automation — conveyor lines, machine tooling, packaging stations.
What the Ratings Mean
The 10-65 VDC supply range covers standard 24 VDC control systems as well as higher-voltage DC rails up to 48 V or 60 V. It will operate on a 24 VDC panel supply without issue, and the wide tolerance gives flexibility in retrofit or mixed-voltage cabinets.
