Working Principle
When a metallic or iron object approaches the sensor head within a 3 mm range:
→ The sensor detects the change in the electromagnetic field.
→ An electrical signal is output via the black wire (NPN Output).
→ This signal can be directly connected to PLC circuits, relays, or controllers.
Applications
- Production line object detection systems
- Automation Machines
- Workpiece counting systems
- Position detection of metallic components
- Replacement for mechanical limit switches
