Pepperl+Fuchs NBN40-U1-A2-T inductieve sensor, 40 mm schakelafstand, PNP NO, IP68 296378,0

In automated production and material handling, reliably detecting metal objects without physical contact is critical to avoid wear and downtime. The Pepperl+Fuchs NBN40-U1-A2-T inductive sensor provides a 40 mm sensing range in a non-flush mountable housing, making it suitable for applications where the sensor cannot be embedded in metal and must detect targets at a distance.

Who is it for

This sensor is intended for industrial automation engineers, machine builders, and maintenance technicians who need a robust, non-contact metal detector for harsh environments. It is particularly useful in conveyor systems, packaging machinery, and assembly lines where objects are metallic and space or mounting constraints require a non-flush installation.

Main features

• 40 mm sensing range for non-flush mounting

• Operating voltage 10–30 V DC
• IP68 protection rating for harsh environments
• PBT housing and PC front cap for durability
• Terminal compartment connection for secure wiring
• Yellow LED switching state indicator
• Short-circuit and reverse polarity protection

Tips

For reliable operation, ensure the sensor is mounted on a non-metallic bracket or with sufficient clearance from metal surfaces, as non-flush sensors are affected by surrounding metal. Verify the supply voltage is within 10–30 V DC and that the load current does not exceed 200 mA. The yellow LED indicates the switching state, aiding in quick diagnostics.
