Overview

The SICK LE20-2621 is a safety light curtain from the LE 20 series, designed for personnel protection in industrial environments. It features a resolution of 30 mm and a protective height of 260 mm. The device operates with a scanning range up to 170 mm and utilizes M12 connectors for power and signal transmission. Key safety functions include beam coding and external device monitoring (EDM) to ensure reliable operation. The unit supports standard safety relay interfaces and complies with relevant machinery safety directives.

Feature Summary

• Provides personnel protection through high-resolution optical sensing
• Integrates beam coding for enhanced interference immunity
• Supports external device monitoring for system integrity verification

Applications

• Machine guarding for press brakes and injection molding machines
• Protection zones around automated assembly equipment
• Safety barriers for robotic cell perimeters

Procurement Notes

Verify the specific订货代号 against the official SICK catalog to confirm compatibility with existing mounting brackets and cable assemblies. Ensure the selected variant matches the required protective height and resolution for the intended safety zone. Cross-reference the connector type with the control system interface requirements before finalizing the order.

Selection Notes

Select this model based on the required resolution of 30 mm and protective height of 260 mm. Consider the operating environment for potential interference sources that necessitate beam coding. Evaluate the available mounting space against the device's depth and the required scanning range. Confirm compliance with local machinery safety regulations regarding performance level requirements.

Part Context

The LE 20 series represents SICK's compact safety light curtain line, balancing robustness with ease of integration. This specific part number corresponds to a standard configuration within the series, offering a fixed protective height suitable for lower-level machine guarding applications. It complements other LE 20 variants that provide different heights or resolutions.

Replacement Considerations

Direct replacements must match the 30 mm resolution and 260 mm height specifications. Verify connector pinouts and mounting hole patterns for mechanical compatibility. Alternative models from the same series may require adapter kits for existing installations.
