Security Light Curtain: It is an infrared safety photoelectric sensor commonly used for safety protection on automated machinery and equipment.
Common industries such as punching machines, hydraulic presses, film cutting machines, metal cutting machines, and grinding tool pressing devices all require a certain level of danger in their workstation operations, which makes it very necessary to install Garantta safety gratings for safety protection.
Garantta Light Curtain can be installed using three main methods: side-mounted brackets, top-down brackets, and steel pipe brackets. The choice should be based on the equipment type and protection requirements, and follow standardized installation procedures.
Common Installation Methods
- Side-mounted brackets: The sliders and side-mounted brackets are secured to the left and right sides of the equipment using square slots on the back of the safety light curtain. The light curtain is screwed to the left and right sides of the equipment. This is suitable for horizontal beam coverage.
- Top-down brackets: L-shaped brackets are installed in the screw holes on the light curtain end caps, securing the brackets vertically to the top and bottom sides of the equipment. This is suitable for applications requiring vertical protection (such as punch presses).
- Steel pipe brackets: The light curtain is secured to an adjustable steel pipe bracket, and its position can be adjusted using sliding screws. This is suitable for complex spaces or applications requiring flexible positioning.
Main Features
1. Excellent engineering design and compact dimensions, measuring only 13 x 28mm and 28 x 35mm
2. Direct cable outlet simplifies wiring, reduces the risk of disconnection, and shortens operational testing time.
3. Ultra-thin design offers flexible use and a compact footprint, resulting in a smaller blind spot within the same protective envelope.
4. Optical synchronization design provides strong resistance to electromagnetic interference.
5. Independent power supply for the transmitter and receiver units facilitates wiring.
6. Equipped with dual NPN/PNP output signal lines.
application cases
1. Injection molding machine and stamping machine industry
Injection molding machine: The working process of the injection molding machine involves dangers such as high temperature and high pressure. A safety light curtain is installed in front of the machine or around the dangerous area. When a worker approaches or enters by mistake, the light curtain detects and sends an alarm signal to automatically stop the machine.
Pressing machine: The stamping machine uses impact force to process metal sheets, which is prone to injuries. The safety light curtain is set above or on the side of the machine. When the operator approaches the dangerous area, the light curtain senses and stops the operation of the stamping machine, which has a good protective effect in high-frequency stamping operations.
2. Automobile manufacturing industry
Protect the safety of workers and robots: In the automobile manufacturing industry, workers often collaborate with large robots. The safety light curtain can sound an alarm and stop the robot's movement when a worker approaches the robot's working area, preventing injury from contact with the robot.
3. Automated production line protection
Used in automated production lines to prevent people from entering dangerous areas and being injured by mechanical equipment. Once someone enters, the safety light curtain immediately stops the machine.
Multi-workshop workstation protection: Applied to multiple workshop workstations, such as the stamping workshop, welding workshop, painting workshop, powertrain, and assembly workshop, to ensure personnel safety and normal equipment operation, such as restricting unauthorized operators in the stamping workshop from entering specific workstations.
4. Express the cabinet industry
Security Light Curtains are used for express cabinets to prevent pinching and theft. When a user takes an item, if their hand is on the path of the cabinet door closing, the light curtain detects and prevents the cabinet door from closing to prevent pinching. If someone illegally pries the cabinet open, the light curtain detects foreign matter and quickly activates the alarm system.
5. Public transportation
Used for equipment such as elevators, escalators, and automatic doors. For example, when the elevator door is closed, if someone enters the light curtain monitoring area, the elevator door will automatically open to avoid pinching accidents and ensure the safety and convenience of passengers.

FAQ
Q: Do Garantta safety light curtains meet EU Machinery Directive & OSHA standards for press machine and robot cell guarding? What safety type & PL level do they support?
A: All Garantta security light curtains comply with EU Machinery Directive 2006/42/EC, EN/IEC 61496-1/2:2020 and EN ISO 13849-1, fully satisfying OSHA machine safety requirements for North American factoriesSchmersal. Our whole series is Type 4 safety light curtains with continuous self-check function, matching PL e / SIL 3 highest safety performance level for high-risk equipment like hydraulic presses, stamping machines and collaborative robot workstations. We hold official EC Type Examination Certificate issued by EU notified body Safenet and TÜV conformity attestation, all certification documents are downloadable on our page for your factory audit.
Q: Will your safety light curtain malfunction under strong arc welding light, sunlight or frequency converter electromagnetic interference on production lines?
A: Garantta ultra-thin safety gratings adopt optical synchronization dual-channel design with 10,000LUX anti-external light interference capability, effectively resisting welding arc flash, workshop high-brightness sunlight and inverter electromagnetic noiseRockwell A.... The transmitter and receiver adopt independent power supply separation design to avoid signal crosstalk; the lens is coated with anti-reflection dust-proof layer to prevent dust accumulation from causing unstable light reception. Unlike ordinary light curtains that frequently trigger false shutdown, our products maintain stable detection without blind spots in harsh automotive welding, metal cutting and outdoor
Q: How do I select the correct optical axis spacing (resolution) for finger/hand/body protection? Are multiple installation bracket options available for compact machine frames?
A: We provide full resolution options covering industrial safety standards: 5/10mm for finger protection (detect tiny fingers for precision punch stations), 20/30/40mm for hand/arm protection, 60mm for whole-body access guarding, fully following EN ISO 13855 human body detection rules. Three standard installation kits are supplied together: side-mounted sliding brackets, vertical top-bottom L brackets and adjustable steel pipe brackets. Our ultra-thin GLC/GLL series (13×28mm /18×35mm housing) fits narrow small equipment gaps without extra modification, and we support customized protection height and cable outlet direction for special machinery layout.
