Robot Cell Safety Sensors Compared
Each sensor type trades coverage against cost and complexity.
Options compared
| Sensor | Best for |
|---|---|
| Light curtain | Defined openings and frequent access |
| Safety laser scanner | Flexible floor zones and mobile areas |
| Safety mat | Floor-level detection in tight spaces |
| Interlocked gate | Positive mechanical protection |
| Vision-based safety | Flexible zones with complex geometry |
Selection notes
- Distances must be calculated from stopping time, not estimated.
- Environmental conditions affect reliability; check dust, glare and vibration.
- Any change to the layout requires re-validation.
Sensor selection follows the risk assessment and applicable standards. Confirm with a competent specialist.
