1047631

Overview

The SICK LE20-2621 is a block-shaped photoelectric sensor from the G10 series, designed for transmission mode applications. It utilizes a polarized red light source to ensure reliable detection of objects against complex backgrounds. The device features an NPN output type and connects via a 4-pin connector interface. This configuration supports panel mounting, making it suitable for integration into industrial automation systems requiring precise object presence verification.

Feature Summary

• Polarized red light source technology for enhanced background suppression
• Block-shaped housing design optimized for transmission mode operation
• NPN switching output for standard industrial control integration
• 4-pin connector interface for simplified wiring and installation

Applications

• Object detection in automated assembly lines
• Presence verification in packaging machinery
• Level monitoring in bulk material handling
• Safety interlock monitoring in industrial equipment

Procurement Notes

Verify the specific part number 1047631 against official SICK documentation to confirm compatibility with your system requirements. Ensure that the NPN output type matches your controller's input specifications. Confirm the 4-pin connector interface aligns with your existing cabling infrastructure. Check for any regional certification requirements or environmental ratings necessary for your specific deployment location before finalizing procurement.

Selection Notes

Select this model when high reliability against reflective or patterned backgrounds is required due to its polarized optical design. The transmission mode setup offers superior stability compared to diffuse reflection types for long-distance detection tasks. Consider the NPN output logic to ensure seamless integration with PLC inputs. The compact block shape allows for flexible mounting options within space-constrained enclosures or machinery frames.

Part Context

This component belongs to the SICK G10 series, known for robust performance in industrial environments. The LE20 designation indicates a specific size class within the transmission sensor lineup. As a dedicated transmission sensor, it operates by detecting interruptions in a light beam between a transmitter and receiver unit, providing consistent results regardless of object color or surface texture.

Replacement Considerations

Consult SICK's official cross-reference guides for direct replacements. Verify that any substitute maintains the same polarized red light wavelength and NPN output polarity. Ensure mechanical dimensions and connector pinouts are compatible to avoid retrofitting issues.
