Pepperl Fuchs Sensors: The Ultimate Guide to Industrial Sensor Selection & Replacement

Pepperl Fuchs is a trusted name in the automation and factory sensor industry. Whether you're in machine building, process industries, or predictive maintenance, sensors are critical. With 70+ years in industrial sensing, Pepperl Fuchs continues to lead with sensors designed for real-world durability and precision.

What Makes Pepperl Fuchs Stand Out?

In a market flooded with sensor brands, Pepperl Fuchs stands out for one reason: reliability. Their sensors are engineered to perform consistently—even in tough industrial environments. From oil-splattered production lines to high-vibration machinery, their products are built to last.

Pepperl Fuchs sensors are used in over 30% of high-end industrial automation systems worldwide.

Types of Pepperl Fuchs Sensors (And Where to Use Them)

Inductive Proximity Sensors

Used for detecting metal without physical contact. Ideal for positioning, object detection on conveyors, and end-of-arm tooling. Models like NBB5-18GM50-E2 & NJ2-V3-N are known for their rugged performance.
Common Use: Automotive, Robotics, CNC Machinery

Photoelectric Sensors

Great for detecting both metallic and non-metallic objects. Available in retro-reflective, diffuse, and through-beam styles. Models like ML100-8-H-100-RT /102/115   are excellent for packaging and counting applications.
Common Use: Packaging Lines, Logistics, Bottling Plants

Ultrasonic Sensors

Best for measuring distance in dirty, dusty, or wet conditions. Models like UC500 F77 U V15 and UB500 18GM75 I V15  are excel here. They emit high-frequency sound waves for precise distance measurement.
Common Use: Waste Management, Liquid Monitoring

Capacitive Sensors

Detect non-metallic objects like paper, plastic, or powder. Useful for bin-level monitoring or plastic detection in packaging machines. Comes with adjustable ranges.
Common Use: Food Industry, Packaging, Granular Material Handling

How to Choose the Right Sensor

Forget technical overload. Here’s how to choose:
- Metal & close range? Go inductive sensors.
- Plastic, cardboard, anything else? Go photoelectric sensors.
- Dirty, wet space with distance measuring? Ultrasonic sensors.
- Non-metal through bags/containers? Capacitive sensors.

Don’t forget to check:
- Mounting space
- Sensor size & housing
- Output type (PNP/NPN)
- Connector type
 

Sensor Replacement: What You Should Know

Replacing a sensor? Here’s the checklist:
- Match the exact model whenever possible.
- Use Pepperl Fuchs’ cross-reference tool for obsolete units.
- Double-check wiring diagrams.
- Confirm IP ratings, especially in wash-down zones.

Over 60% of sensor failures in industrial setups are due to incorrect replacements or wiring issues.

Common Troubleshooting Tips

Before assuming a sensor is faulty, try these:
- Verify correct wiring.
- Clean the sensor surface.
- Look for overload signs.
- Use the indicator LED to check power and operation.
