Siemens 3RG4613-3WS00 AS-I Inductive Switch, M18, 5mm Shield

The 3RG4613-3WS00: For a DCS engineer or MRO planner looking at a swap: the 5 mm shielded range is standard for flush mounting in metal — the face can be level with the surrounding steel without false triggers. The M12 connector is a 4-pin male, typical for AS-I (brown/blue for power, black/white for data). No wiring diagram is in this listing, but the AS-I pinout is consistent across the standard: pin 1 brown (AS-I+), pin 3 blue (AS-I-), pin 4 black (data), pin 2 white (data).
