What Is a Light Curtain Sensor Used For?
Workplace injuries happen too often; light curtain sensors protect operators instantly.
Light curtain sensors create a protective barrier with light beams, stopping machines when the barrier is broken.
Light curtain sensors are critical in industrial safety.
How They Work
These sensors use multiple infrared beams. If any beam is interrupted, the sensor signals the machine to stop immediately.
Applications
Light curtains are widely used on presses, robotic cells, and hazardous zones. They prevent accidents while allowing continuous workflow.
| Feature | Description |
|---|---|
| Beam Count | From 4 to over 30 |
| Safety Category | ISO 13849 compliant |
| Response Time | Very fast, milliseconds |
| Use Case | Operator protection, machine guarding |
I often design systems combining light curtains with emergency stops and safety mats. Proper positioning ensures full protection while keeping production efficient.
