Safety Light Curtains for Public Space Security

Table of Contents

Public Space Security:

Banks, Shopping Malls and More

Safety light curtains provide reliable security monitoring in public environments such as banks and shopping malls, protecting both people and property. In retail stores and supermarkets, for example, light curtains detect the position of items as they are scanned and placed, helping to prevent missed scans and operating errors. At self-checkout counters, they monitor the position and movement of objects in real time, ensuring the safety of both personnel and equipment.

Robot Safeguarding

Installing DASS safety light curtains around a robot work cell enables continuous monitoring of approaching people or objects. When a person or object enters the protected zone, the light curtain immediately signals the robot to stop or slow down, preventing collision. This safeguards both personnel and equipment, keeping automated production safe, stable and uninterrupted.

Logistics and Warehousing

Sorting, Handling and Storage

In automated logistics systems, safety light curtains provide direct, non-contact detection of the presence and position of goods, supporting the stable operation of automated equipment. Configured as measuring light grids, they capture the height, width and length of parcels and pallets with high resolution, enabling accurate profiling for sorting, conveying and storage. This helps automated stackers, shuttles and conveyors avoid collisions with oversized or misaligned loads, reducing product damage and unplanned downtime.

Monitoring Safe Stacking Height

Light curtains can also be applied to monitor the safe stacking height of goods. Once a stack exceeds the predefined limit, the system triggers an alarm or interlock signal immediately, preventing collapse-related incidents and protecting personnel working in the vicinity.
