Pepperl Fuchs 3RG6233-3LS00 Sensor

Pepperl+Fuchs 3RG6233-3LS00 Sensor (Ultrasonic Distance Sensor – M18 Industrial Proximity Sensor)

 

 

The Pepperl+Fuchs 3RG6233-3LS00 is an ultrasonic proximity / distance sensor, used for non-contact detection of objects and distance measurement in industrial automation systems.

Product Information

• Brand: Pepperl+Fuchs (Germany)
• Model: 3RG6233-3LS00

What it actually is

This is a distance measuring sensor using ultrasonic waves, meaning:

• Sends ultrasonic pulse → reflects from target → measures return time
• Calculates distance to object or liquid surface
• Outputs analog signal or switching signal to PLC

It is NOT a PLC module, NOT a controller, NOT a relay.

System Role (Simple)

Object / material / surface
→ ultrasonic echo
→ 3RG6233 sensor (this unit)
→ analog signal (4–20 mA / voltage)
→ PLC / controller reads distance

So it acts like a “non-contact distance measuring sensor for automation systems.”

Key Features

• Non-contact measurement (no wear)
• Works on metal, plastic, liquid, irregular surfaces
• High immunity to dust, color, transparency changes
• Analog output for continuous distance measurement
• Industrial rugged M18 metal housing
• IP67 protection for harsh environments

Typical Applications

• Level measurement (liquids / tanks)
• Conveyor object detection
• Position monitoring in machines
• Packaging machinery
• Material handling systems
• Distance control in automation lines

Advantages

• Works regardless of object color or material
• No mechanical contact → no wear
• Reliable in dusty / dirty environments
• Simple PLC integration (analog input)
• Compact M18 installation size

Important Notes

• Not PLC CPU ❌
• Not I/O module ❌
• Not communication device ❌
• Not switch/relay ❌
• It is a ultrasonic analog distance sensor ✔

Precautions

• Avoid extreme angle reflection surfaces (affects accuracy)
• Keep minimum blind zone distance
• Must align correctly with target surface
• Electrical noise shielding recommended for analog output
• Do not exceed supply voltage (typically 30V max class)
