• Type: Inductive Proximity Sensor (Non-shielded / Non-flush) 
• Configuration: DC 2-Wire, Normally Closed (NC) 
• Operating Voltage: 6–36V DC (or 10–30V DC depending on the manufacturer spec) 
• Sensing Distance: 8mm nominal (approx. 6.4mm effective setting distance) 
• Output Current: 200mA to 300mA max 
• Detection Object: Magnetic/ferrous metals (like iron) 
• Protection Rating: IP65 (dust-tight and water jet protected) 

Critical Wiring Warning

• Series Connection Only: The electrical load must be connected in series with the sensor. Connecting the brown (+V) and blue (0V/GND) wires directly to a power supply without a load will cause an immediate short-circuit and destroy the device.
• Color Coding: Brown wire connects to positive (+V) via the load; Blue wire connects to negative/ground (0V). 

For further assistance, specify:

• The type of load or microcontroller being connected.
• If a wiring diagram is required for a PLC or relay
