Inductive Proximity Sensor, pepperl & fuchs NEB12-18GM50-E2-V1, PNP, model 231731

The inductive proximity sensor pepperl & fuchs NEB12-18GM50-E2-V1 is a PNP switching device for non-contact detection of metallic targets in industrial automation. Built for reliable object sensing, this sensor is suitable for installation in machinery, conveyor systems and positioning applications where robust detection of metal parts is required. The compact cylindrical housing and defined sensing range enable integration in tight mounting spaces and repetitive detection tasks.

Advantages

This inductive sensor offers stable PNP switching behaviour and consistent detection of ferrous and non-ferrous metal objects without physical contact, reducing mechanical wear. Its design provides immunity to dust and moderate contamination common in factory environments, ensuring long-term operational stability. The tubular form factor and standard mounting dimensions simplify replacement and integration into existing automation setups.

Suitable for

• Presence detection of metal parts on conveyors and assembly lines
• End-of-travel and position sensing in linear actuators and slide systems
• Counting and process control tasks in production equipment
• Integration into PLC-controlled automation and safety interlocks (as a sensing element)

Key specifications

• Sensing principle: inductive, non-contact detection of metallic targets
• Switching type: PNP normally open/closed configuration (as specified by model)
• Mounting style: cylindrical tubular housing suitable for flush or non-flush mounting
• Sensing range: defined short-range detection optimized for close-proximity metal sensing
• Electrical interface: three-wire connection compatible with standard industrial control inputs
• Environmental resistance: designed for industrial ambient conditions with protection against dust and moderate contamination

How to use

Install the sensor in the intended mounting position, ensuring the sensing face faces the target and that the correct mounting distance is maintained according to the sensor’s sensing range. Connect the three-wire PNP output to the machine control or PLC input following the wiring polarity: power supply, ground and PNP signal output. Verify switching behaviour with the target material and adjust mounting or shielding if nearby metal structures affect sensing. Test operation under normal process conditions before full production use.

Usage recommendations

Use this inductive proximity sensor where reliable, repeatable detection of metal objects is required and avoid exposing the sensing face to direct mechanical impact. For stable performance, maintain proper wiring practices, provide surge protection as needed in noisy electrical environments, and follow the manufacturer’s guidelines for mounting distances and environmental limits.
