Light Curtains and Safety Mats
Selection factors
| Factor | Why it matters |
|---|---|
| Protective height | It must cover the whole opening to the danger zone |
| Resolution | It determines the smallest object detected |
| Response time | It feeds directly into the safety distance calculation |
| Environment | Dust, oil mist and moisture affect reliability |
Maintenance points
- Test every beam periodically with the specified test rod.
- Clean lenses and surfaces with a soft cloth to avoid blind spots.
- Replace mats that are deformed or have taken in water.
- Re-verify the interlock after any replacement.
Safety distance depends on both the standard and the device response time. Have it calculated properly.
