Overview

The SICK LE20-2621 is a laser distance sensor belonging to the LE 20 series, designed for precise non-contact measurement in industrial automation environments. This specific model features a measuring range of 250 mm with a resolution of 0.1 mm and an accuracy of ±1 mm. It utilizes a red laser diode (635 nm) for target visualization and supports analog output signals including 4-20 mA and 0-10 V. The device operates on a supply voltage of 10-30 V DC and provides protection against environmental interference suitable for factory floor applications.

Feature Summary

• High-resolution laser triangulation technology for accurate distance measurement
• Integrated red laser pointer for precise target alignment
• Dual analog output capability for flexible system integration
• Robust housing design suitable for industrial automation settings

Applications

• Object detection and positioning in automated assembly lines
• Level monitoring in tanks and silos
• Presence detection for packaging machinery
• Distance verification in quality control systems

Procurement Notes

Verify the complete order number includes all necessary configuration suffixes for cable length and connector type. Confirm that the analog output signal requirements match your PLC or controller input specifications. Ensure the operating environment temperature falls within the specified limits for the LE 20 series. Check for any required mounting accessories separately as they are often sold independently.

Selection Notes

Select this model when a short-range, high-precision measurement solution is required. Compare the 250 mm range against application needs to ensure sufficient margin. Consider the LE 20 series alternatives if digital interfaces like IO-Link are preferred over analog outputs. Evaluate the IP rating requirements against the installation location's exposure to dust or moisture.

Part Context

This component is part of SICK's LE 20 family of laser distance sensors. The series is engineered for cost-effective, reliable performance in standard industrial applications. It complements SICK's broader portfolio of safety and process sensors by providing essential dimensional data for logistics and manufacturing processes.

Replacement Considerations

Check for updated revisions within the LE 20 series that may offer improved connectivity. Verify compatibility with existing mounting brackets and cables from previous installations. Consult SICK documentation for cross-reference tables regarding legacy models with similar measuring ranges.
