Summary
By selecting the Front Ultra-thin Safety Light Curtain QZ Series, the enterprise successfully solved the challenge of installing safety light curtains in a space-constrained production line.

Background
In automated production lines, safety is a crucial factor in both design and operation. Especially when installing safety light curtains in space-constrained equipment, it's essential to meet safety protection requirements while considering operational ease and spatial limitations. A certain manufacturing enterprise faced this challenge on its assembly line: how to install safety light curtains in a limited space to prevent operators from entering hazardous areas while ensuring that the light curtains do not interfere with each other.
Needs Analysis
The assembly line of the enterprise required the following safety protection:
1. Finger Protection: The production line requires delicate operations, so the safety light curtain needs to detect small objects like fingers to prevent injuries.
2. Operational Convenience: Operators need to operate equipment conveniently, so the safety light curtain cannot completely enclose the work area.
3. Close Installation: Two safety light curtains need to be installed in close proximity without interfering with each other.
Project Challenges
1. Finger Protection Difficulty: Detecting small objects like fingers is a challenge, as standard safety light curtains may not be effective at detecting them.
2. Space Constraints: Installing safety light curtains in limited space must not interfere with the operators' work or the normal operation of the equipment.
3. Light Curtain Interference: Installing two safety light curtains too close to each other could cause interference, affecting detection accuracy.

Solution
After evaluation, the enterprise chose the DADISICK Front Ultra-thin Safety Light Curtain QZ Series. This light curtain offers the following advantages:
1. Ultra-thin Design: With a cross-sectional size of only 17.2x30mm, it's nearly 50% thinner than standard safety light curtains, saving significant installation space—ideal for production lines with space constraints.
2. High-Precision Detection: Capable of detecting small objects like fingers, ensuring safety during delicate operations.
3. Anti-interference Design: Even when installed in close proximity, the light curtain prevents mutual interference, maintaining accurate detection.
4. Flexible Installation: The installation method is versatile and can be adjusted according to the specific needs of the production line, ensuring safety without affecting operational convenience.
