Output rating and supply
The XS4P12PB370 is a Schneider Electric inductive proximity sensor rated for 24 VDC supply and 200 mA switched output. That 200 mA figure is the maximum continuous load the sensor's output transistor can sink — it covers direct drive of a small relay coil or a PLC input module, but if you're switching a solenoid or contactor, check the inrush against the 200 mA ceiling.
