Introduction
In modern industrial environments, operator safety and machine protection are major issues. Safety photoelectric barriers play a crucial role in accident prevention and compliance with international standards.
Among the most reliable and high-performance solutions on the market, the Tem range from SICK stands out for its robustness, ease of integration, and ability to secure critical areas, even in demanding environments.
What is a safety photoelectric barrier?
A safety photoelectric barrier is an optoelectronic device that uses an infrared light beam to create a protection zone.
When an object, a hand, or a human body interrupts the beam, the system sends an immediate stop signal to the machine.
These devices often replace traditional mechanical safeguards (covers, grilles), providing both safety and work ergonomics.
The strengths of the SICK deTem range
- Reliable access protection: designed to secure entry into hazardous areas.
- Extended ranges: up to 90 m, depending on the configuration.
- Ease of installation: compact enclosures, flexible mounting, simplified alignment.
- Industrial robustness: resistance to shocks, vibrations, dust and splashes (IP65 / IP67).
-
Advanced features:
- Cascading function to connect multiple barriers in series without loss of performance.
- Muting and Blanking available to allow the temporary passage of loads without disabling safety.
- Clear diagnostics with LED and communication options.
- Compliance with international standards: CE certification, TÜV, and adherence to ISO 13849 and IEC 61496 standards.
Typical applications of deTem
- Machine access: protect the entry into robotic cells or hazardous work areas.
- Automated conveyors: securing areas where parts, pallets, or loads pass through.
- Logistics and storage: protecting the aisles in automated warehouses.
- Automotive and electronics industry: ensuring safety around assembly and manufacturing stations.
- Challenging environments: thanks to their robustness, the deTem remain reliable in dusty, humid, or vibrating areas.
Advantages for manufacturers
- Increased productivity: no need to manually open/close covers, the barrier protects automatically.
- Reduction of unexpected downtime: clear diagnostics and reliable installation minimise interruptions.
- Flexibility: easily adapts to changing production lines thanks to the cascade system and advanced features.
- Quick return on investment: fewer accidents, greater machine availability, ensured legal compliance.
Limits and points of caution
- Need for precise alignment for optimal detection.
- Possible sensitivity to strong stray lights (adjustment required).
- Not suitable for explosive environments (provide specific ATEX solutions).
Conclusion
The SICK deTem range stands out as an essential solution for securing access to machines and hazardous areas. Combining extended range, robustness, and ease of integration, these photoelectric barriers meet the needs of manufacturers looking to protect their operators while maintaining high productivity.
