Pepperl Fuchs 3RG6115-3BE00-PF Proximity Sensor

Pepperl+Fuchs 3RG6115-3BE00-PF Ultrasonic Proximity Sensor

 

 

The Pepperl+Fuchs 3RG6115-3BE00-PF is an ultrasonic distance / proximity sensor designed for non-contact level and position detection of objects and materials such as plastic, wood, metal, liquids, and bulk solids.

It is widely used in industrial automation where optical or inductive sensors are not suitable due to dust, color, or transparency issues.

• Stable output: 4–20 mA analog signal proportional to distance
• Adjustable sensing range via potentiometer / programming
• High immunity to dust, humidity, and lighting conditions
• Suitable for continuous industrial monitoring

Application Areas

• Tank and silo level measurement
• Conveyor object detection
• Packaging machinery
• Material handling systems
• Liquid and bulk solid level monitoring
• Automation production lines
• Position detection in harsh environments

Advantages

• Works where optical sensors fail (dust, fog, color variation)
• Long detection range up to 3 meters
• High measurement stability and repeat accuracy
• Easy integration into PLC systems via 4–20 mA
• Rugged industrial M30 metal housing
• Low maintenance (no moving parts)

Precautions

• Must avoid strong acoustic reflections from nearby structures
• Proper alignment required for accurate measurement
• Do not exceed 30 VDC supply voltage
• Ensure stable mounting to avoid vibration errors
• Cable shielding recommended for long-distance analog signal wiring
