German Beckhoff P+F Inductive Proximity Sensor NBN Series

German Beckhoff P+F Inductive Proximity Sensor NBN Series

1、 Overview of NBN Series

• typeInductive proximity sensor (detecting metal objects).

• positioningEconomical basic model, high cost-effectiveness, suitable for conventional industrial environments.

• core functionalityNon contact detection of metal targets (such as iron, steel, aluminum, etc.), outputting switch signals.

2、 Model Naming Rules

ToNBN8-18GM50-E2For example:

• NBNSeries name.

• 8Shell diameter (8mm).

• 18Detection distance (18mm, for iron standard targets).

• GMThreaded installation (others such as "FL" indicate flush installation).

• 50Cable length (50cm, optional other lengths).

• E2Output configuration (E2 represents NPN normally open, while others such as "V1" represent PNP normally closed).

3、 Main models and parameters

4、 Product Features

1. cost-effective

• Complete basic functions and low-priced series (such as NCB or NMB), suitable for projects with limited budgets.

2. Stable detection

• The detection distance is 10% of the nominal value (e.g. the detection distance of NBN8-18GM50 is 1.8mm ± 10%).

• The anti electromagnetic interference (EMC) performance complies with the IEC 60947-5-2 standard.

3. Durable design

• Stainless steel or nickel copper alloy shell, protection level IP67 (dustproof and waterproof).

• Working temperature range: -25 ° C to+70 ° C.

4. Flexible installation

• Provide flat (FL) and non flat (GM) installation options to adapt to different installation environments.

5、 Typical application scenarios

1. Production line positioning

• Detect the position of metal components on the robotic arm (such as cylinder pistons).

2. Material Counting

• Counting the passage of metal parts on the conveyor belt (to be used in conjunction with a counter).

3. Equipment safety

• Monitor whether the machine door is closed (by detecting the metal door frame).

4. automated assembly

• Confirm whether the metal parts are in place (such as the car screw assembly station).

6、 Selection precautions

1. detection distance

• The actual detection distance is affected by the target material (the detection distance for aluminum is about 50% of that for iron).

2. Output configuration

• NPN（E0/E2）Suitable for leakage type input of PLC (such as Japanese PLC).

• PNP（V1/V3）Suitable for source input (such as European PLC).

3. Installation method

• Flat Installation (FL)Can be embedded in metal slots to avoid mechanical collisions.

• Non flush installation (GM)The detection distance is longer, but it needs to be prominently installed.

4. environmental adaptability

• Avoid using near strong magnetic fields or high-frequency welding equipment as it may interfere with the signal.

7、 Frequently Asked Questions (FAQ)

• Q1: Can the NBN series detect non-metallic objects?
  → No, inductive sensors only detect metals. To test plastics/liquids, capacitive type (such as NC series) should be selected.

• Q2: Can the BN8-18GM50-E2 cable be extended?
  Okay, but it is necessary to shield the cable and avoid signal attenuation (recommended not to exceed 10 meters).

• Q3: What is the difference with the NMB series?
  NMB is a Beijiafu electric sensing sensor with higher detection accuracy (± 3%), suitable for harsh environments.

8、 Recommended alternative models

• Need for longer detection distanceChoose NBN15-30 series (maximum 30mm).

• Higher protection levelChoose NMB8-18GM50-E2 (IP68, oil resistant).

• IO Link functionChoose NBN8-18GM50-E2-IO (supporting intelligent diagnosis).
