Certified Safety. Instant Protection.
XSZ standard safety light curtains provide a reliable invisible barrier for hazardous machinery. With ultra-fast response times and high-resolution detection, we safeguard your workforce without compromising productivity.
Tailored Protection Resolution
The distance between light beams determines the level of safety. Choose the right resolution to ensure your safety distance complies with ISO 13855 standards.
Finger Protection
Designed for high-risk zones where the operator's fingers may reach hazardous areas. Ideal for small assembly stations and electronics manufacturing.
Hand Protection
The industry standard for most machinery. Provides reliable detection of a human hand, balancing cost-effectiveness and high-level safety.
Body & Arm Protection
Used for perimeter guarding and access control. Detects whole limbs or a person's entry into a large robot cell or automated warehouse area.
Remember to calculate the minimum safety distance ($S$) using the formula: $S = K \times T + C$. Our technical team can help you determine the correct mounting distance based on your machine's stopping time.
The Science of Fail-Safe Reliability
Our safety architecture is engineered to eliminate single-point failures. XSZ light curtains don't just detect—they actively monitor their own integrity 100 times per second.
Dual OSSD Outputs
Features two independent Output Signal Switching Devices (OSSD). This dual-channel design ensures that if one circuit fails or shorts, the second channel provides an immediate emergency stop signal.
Real-time Self-Checking
Embedded with redundant logic processors, the system performs a full diagnostic sweep of its internal components and optical beams every few milliseconds, meeting SIL3 safety requirements.
Optical Synchronization
Advanced beam coding allows the transmitter and receiver to sync wirelessly. This eliminates the need for a synchronization cable, reducing wiring complexity and boosting EMI resistance.
Strong Ambient Light Filter
Using proprietary ASIC digital filtering, our sensors remain operational even under high-intensity welding arcs or direct sunlight interference, preventing annoying "nuisance trips."
Industrial-Grade Durability
Safety shouldn't be fragile. XSZ light curtains are encased in aviation-grade aluminum and sealed against the harshest factory conditions to ensure 24/7 operational uptime.
IP65/IP67 Sealed Housing
Fully protected against high-pressure wash-downs, oil mist, and fine industrial dust. The seamless encapsulation ensures internal electronics remain bone-dry in humid environments.
Superior Vibration Resistance
Specifically reinforced for stamping presses and heavy-duty vibrating machinery. Internal shock absorbers prevent beam misalignment caused by constant mechanical impact.
Aviation-Grade Aluminum
The 1.5mm thick extruded aluminum alloy housing provides exceptional structural rigidity, protecting the optical lenses from accidental side-impacts and bending.

Proven Safety: Engineered for Harsh Zones
XSZ safety light curtains are trusted by global industrial engineers to safeguard high-risk manufacturing cells without impacting automated workflow cycles.
Automotive Stamping Presses
In high-tonnage metal forming, severe mechanical shock is the primary enemy of optical alignment. XSZ curtains are integrated with vibration mitigation housing and reinforced optical brackets, ensuring the safety circuit stays active despite continuous structural impact.
- 14mm Finger Resolution
- High Shock Absorption
Robotic Automation Cells
Safeguarding the spatial perimeters of high-speed welding and palletizing robots. Our long-range optoelectronic barriers (up to 15m) generate an invisible multi-beam safety perimeter. The sub-15ms reaction speed permits closer machine mounting, reclaiming valuable production floor space.

Trusted by Safety Engineers
"We upgraded our entire stamping line to XSZ **Type 4 light curtains**. The stability against high-frequency vibration is impressive. Most importantly, it passed our **SIL3 safety audit** with flying colors."
"The **Built-in Laser Alignment** saved us hours of setup time on our robotic welding cells. We used to struggle with ambient light interference, but XSZ's digital filtering solved it completely."
Frequently Asked Questions
What is the difference between Type 2 and Type 4 light curtains?
+Type 4 (SIL3/PLe) curtains have continuous self-checking and higher redundancy, making them mandatory for high-risk zones like power presses. Type 2 (SIL1/PLc) is suitable for lower-risk areas where occasional failures don't lead to immediate danger.
How do I calculate the correct Safety Distance (S)?
+The safety distance is calculated based on the formula: **S = (K × T) + C**, where K is the approach speed, T is the total response time of the system, and C is the intrusion distance based on resolution. Our 14mm resolution allows for a much smaller C-value, saving floor space.
Does the sensor work near high-frequency welding machines?
+Yes. XSZ safety light curtains are equipped with proprietary **ASIC optical filtering** that ignores the flash and EMI generated by welding arcs, preventing nuisance trips and keeping your line running.
What happens if one beam is damaged?
+Due to the **Dual-OSSD fail-safe architecture**, if any internal beam or circuit fails, the light curtain will immediately enter a "Lockout" state and send a stop signal to the machine, ensuring absolute safety.
