DADISICK Safety Light Curtain Series Comparison Guide

However, selecting the correct series requires more than comparing prices or basic specifications—it demands a clear understanding of structural design, protection logic, installation constraints, and operating environment.

This article provides a systematic comparison of all DADISICK safety light curtain series, helping engineers, system integrators, and machine builders quickly identify the most suitable solution for their application.

· Limited installation space

· Large or tall protection areas

· Multi-directional access

· Harsh or wet environments

· Budget-sensitive projects

Using an inappropriate series can lead to:

· Over-engineering and unnecessary cost

· Installation conflicts

· Incomplete access protection

A structured comparison ensures effective protection without excessive complexity.

Rather than listing products individually, the following table compares the series based on official product positioning and real-world application characteristics.

1. Classification by Structural Design

· Ultra-compact designs:

QBT (side-compact), QZ (front ultra-thin)

· Standard structural designs:

QCE, QM, KT, QO, QRF

· Expandable or modular structures:

QT4 (cascade configuration)

· Single-plane access protection:

QCE, KT, QM, QBT, QZ, QRF

· Wide-area or long-distance protection:

QT

· Dead-zone elimination:

QO

· Vertical extended protection:

QT4

· Multi-directional access protection:

QSA

3. Classification by Operating Environment

· Standard industrial environments:

QCE, QT, QO, QT4, KT, QBT, QZ, QM, QSA

· Harsh or wet environments:

QRF

1. Define access direction and protection height

2. Evaluate installation space constraints

3. Assess environmental exposure (water, dust, cleaning)

4. Balance safety requirements and project budget

The optimal solution is the series that meets safety requirements precisely—without unnecessary over-specification.

Safety performance depends on correct application, not series complexity.

"All safety light curtains are interchangeable."

Differences in structure and detection logic directly affect protection effectiveness.

"Compact designs reduce safety performance."

Compact series optimizes form factor while maintaining required safety functions.

Yes. Each series is designed for industrial machine safeguarding when properly selected and installed.

QBT and QZ are optimized for side-limited and front-limited installations.

QSA is specifically designed for multi-sided and enclosed access areas.

QT4 uses a cascade structure to achieve extended vertical coverage.

Final risk assessment, product selection, system integration, and compliance verification must be carried out by qualified safety professionals in accordance with applicable standards and local regulations.

By comparing structure, protection logic, installation constraints, and environment suitability, engineers can confidently select the most appropriate solution for their application.
