Safety Light Curtains for Machine Guarding.
XSZ safety light curtains help protect operators around presses, cutting machines, packing equipment, handling stations and automated production lines. Choose by protection height, beam spacing, detection distance, response time and safety output requirement.
Protect the operator without blocking normal machine access
Mechanical guards can slow down loading, unloading and adjustment work. Safety light curtains create an optical protection zone so the machine can stop when a hand, arm or body enters the danger area.
Open access guarding
Keep the work area accessible while monitoring the opening with multiple infrared beams.
Risk-area stop signal
When the protected field is interrupted, the safety system can send a stop signal to the machine control circuit.
Flexible machine integration
Choose protection height, beam spacing, cable direction and mounting style according to machine layout.
For presses, cutting machines, packing lines and automated workstations
Safety light curtains are used where operators need frequent access to a hazardous area and the machine must stop when the protected field is interrupted.
- Press machines, punching machines and forming equipment
- Cutting, shearing, bending and assembly workstations
- Packaging machines, palletizing areas and conveyor access points
- Robotic loading, material handling and transfer equipment
- Wet, dusty or compact machine areas with special installation needs
Choose by protection height, beam spacing and safety distance
The right light curtain depends on what must be protected, how large the opening is and how quickly the machine can stop after the protected field is interrupted.
| Selection Point | Customer Problem | Recommended Check | Information to Provide |
|---|---|---|---|
| Protection height | Protected field does not fully cover the access opening | Measure the dangerous opening and operator access area | Required protection height and machine opening size |
| Beam spacing | Wrong resolution may not suit hand, arm or body protection | Select spacing by the smallest object that must be detected | Finger, hand, arm or body protection requirement |
| Detection distance | Emitter and receiver cannot communicate reliably | Confirm distance between two light curtain columns | Required sensing distance and mounting layout |
| Safety distance | Machine may not stop before the operator reaches the hazard | Consider machine stop time, approach speed and installation distance | Machine stop time, risk area distance and safety control design |
| Output interface | Output does not match controller or relay circuit | Confirm safety output, voltage and wiring logic | Voltage, output type, controller input and wiring diagram |
Choose the light curtain series by machine environment and installation space
Standard, waterproof, compact and optical synchronous light curtains solve different installation problems. Start with the machine environment, protected opening and wiring layout.
Standard Light Curtains
For general machine guarding where the installation space and environment are stable.
Waterproof Light Curtains
For production areas with water, cleaning, spray or higher enclosure requirements.
Compact Light Curtains
For machines with limited mounting width or compact frame design.
Prevent protection gaps, nuisance stops and wiring delays
Most light curtain selection mistakes come from choosing only by height. Beam spacing, stop distance, mounting position, controller input and environment must be checked together.
Wrong beam spacing
A light curtain for body detection is not the same as a light curtain for hand or finger protection.
Insufficient safety distance
The light curtain must be installed far enough from the hazard according to stop time and approach speed.
Poor alignment or reflection
Misalignment, vibration, reflective surfaces or weak mounting can cause unstable output and unexpected stops.
Safety light curtain options for OEM machines and replacement projects
XSZ supports model matching by protection height, beam spacing, detection distance, output interface, cable requirement and machine environment. Available options depend on the selected series.
Height and beam spacing
Select the protected height and beam pitch according to the opening size and required detection object.
Output and wiring
Confirm voltage, safety output, cable length, connector type and controller or safety relay input before sample production.
Environment and mounting
Choose standard, waterproof, compact or optical synchronous series based on water, dust, space and alignment needs.
Stable machine protection depends on opening size, stop time and installation design
Send real machine details before ordering. A light curtain that fits one press, conveyor or packing machine may not fit another machine with different risk distance and controller design.
| What to Confirm | Why It Matters | What to Send XSZ |
|---|---|---|
| Protected opening | Height and width define the required curtain size | Opening height, opening width and machine photos |
| Protection object | Finger, hand, arm and body protection need different beam spacing | Required protection type and risk area description |
| Machine stop time | Safety distance depends on how quickly the machine stops | Stop time, approach direction and distance to hazard |
| Mounting condition | Alignment and vibration affect stable operation | Bracket design, mounting distance and installation space |
| Environment | Water, dust, oil mist and ambient light affect product selection | IP requirement, cleaning condition and workshop environment |
| Controller input | Output wiring must match the safety control system | Voltage, output type, safety relay or PLC input and cable requirement |
