• Wiring: Three wires - Brown (Power), Blue (Ground), and Black (Signal Output).

Features:

• Non-Contact Detection: Detects metal objects without physical contact, reducing wear and tear.
• Durability: Resistant to dust, dirt, and moisture, making it suitable for harsh industrial environments.
• Easy Installation: Threaded body for easy mounting with standard nuts and brackets.
• High Repeatability: Consistent performance in repeated detection cycles.
• Short Circuit and Overload Protection: Ensures longevity and safety of the sensor and connected devices.

Typical Applications:

• Industrial Automation: Used in conveyor systems, robotic arms, and other automated machinery for position sensing and object detection.
• Safety Systems: Used in machine safety systems to detect the presence or absence of machine parts.
• Counting and Sorting: Ideal for applications requiring counting or sorting of metal parts.
• Limit Switching: Functions as a limit switch in various machinery and equipment.

Operating Principle:

Inductive proximity sensors work on the principle of electromagnetic induction. When a metal object enters the sensor's electromagnetic field, it disrupts the field and induces eddy currents in the metal object. This change is detected by the sensor's internal circuitry, which then activates the output signal.

Installation Tips:

• Mounting Distance: Ensure the sensor is mounted within the specified 8mm detection range for accurate detection.
• Alignment: Align the sensor face perpendicular to the target object's path for optimal performance.
• Environmental Considerations: Ensure the sensor is protected from excessive vibration, extreme temperatures, and direct exposure to chemicals or heavy moisture, even though it is designed to withstand industrial environments.
