Light Curtain Sensor With 12 Beams And 525mm Height
Brand: BORDSTRACT Store. Features emphasize infrared scanning detection for reliable safety, fast response, and strong anti-interference performance. The aluminum alloy construction supports durability in forging machines, automation lines, and otherIndustrial setups. Best for mid-sized machines requiring quick stopping protection. A potential limitation is the absence of detailed installation dimensions in the summary, so verify mounting compatibility before purchase.
CGOLDENWALL Safety Light Curtains (10 Beams)
Brand: CGOLDENWALL Store. The unit features a robust aluminum housing, quick 10 ms detection, and IEC61496-1/2 compliance with CE certification. Suitable for environments following European standards and needing precise monitoring with reliable safety stops when blocked. Limitation: height and beam count are modest, so larger or more complex protection zones may require higher-beam models.
Antstone Safety Light Curtain (8 Beams)
Brand: Antstone Store. Highlights a 0.01 second fast reaction and a 5-meter detection range. The design supports independent power, resistance to EMI, and stable output, reducing the need for a synchronization line. Best for personnel safety on mid-range machines, but fewer beams mean smaller coverage and potential gaps in larger setups.
CGOLDENWALL Safety Light Curtain (26 Beams)
Brand: CGOLDENWALL Store. This model offers 26 beams with a 1000mm protection height (1080mm total). It combines a thick aluminum shell, reliable safety, and fast 10 ms detection. It’s well-suited for large machines requiring broad coverage and high-security standards. A caution: higher beam counts may demand more complex setup and alignment during installation.
Antstone Safety Light Curtain (4 Beams)
Brand: Antstone Store. Notable for its rapid 0.01 second response and EMI resistance. The 4-beam configuration is suitable for compact, low-coverage safeguarding on smaller lines. Consider higher-beam options if broader protection is required for larger equipment or longer access zones.
Buying Guide
What to consider when choosing a safety light curtain sensor
- Beams and coverage: Higher beam counts give broader protection. Choose a model with enough beams to cover the machine’s access areas without gaps.
- Protection height and total height: Ensure the curtain reaches the required guard height for the risk area and accounts for mounting hardware.
- Response speed: Faster responses reduce risk in high-speed machinery. Look for devices with sub-10 ms or around 10 ms ranges for critical lines.
- Housing and durability: Aluminum alloy housings provide robust protection in industrial environments. Consider environments with dust, welding sparks, or vibrations.
- Standards and certification: IEC61496-1/2, CE, and other regional standards indicate compliance with safety expectations. Verify compatibility with local regulations.
- Power and installation needs: Some models require independent power supplies or specific synchronization. Plan for cabling, controllers, and mounting.
- Interference resistance: EMI resistance improves reliability in factory environments with electrical noise. Check specifications for anti-interference performance.
- Maintenance and diagnostics: Look for clear indicators and simple diagnostics to reduce downtime during testing and maintenance.
Frequently Asked Questions
- What is a safety light curtain sensor used for?
It is a protective device that detects human presence in a machine’s danger zone and stops or controls equipment to prevent injury.
- How do I choose the right number of beams?
Assess the machine’s access points and the risk area. More beams provide better coverage but may require more space and alignment effort.
- Do these devices meet international safety standards?
Many models mention IEC61496-1/2 and CE certification. Confirm the exact standard compliance with the seller or datasheet before purchasing.
- Can these sensors be used with different machines?
Yes, most models are designed for use with industrial automation equipment, but verify mounting compatibility and required power connections.
- What maintenance is required for safety light curtains?
Regular inspection of beams, housing integrity, and cable connections helps ensure consistent protection. Replace damaged components promptly.
- Are there safety limitations to consider?
Be mindful of installation gaps, misalignment, or environmental interference that can affect performance. Choose models with appropriate robustness for the setting.
