What the 30mm barrel and DC 2-wire output mean on the line
The XS530B1DBL5 is a 30mm DC 2-wire proximity sensor from the XS5 series, built for industrial presence detection where you need a clean on/off signal without a separate load supply — the two wires carry both power and the switching signal, which simplifies the cable run but means the leakage current through the sensor when off has to be low enough not to ghost a PLC input.
