• Features a robust rectangular housing suitable for industrial mounting
• Equipped with an NPN switching output for standard PLC integration

Applications

• Object presence detection on conveyor systems
• Packaging machine safety interlocks
• Automated assembly line monitoring

Procurement Notes

Verify the specific suffix code to ensure correct cable length and connector type compatibility with existing system wiring. Confirm that the NPN output logic aligns with the control unit input requirements. Check environmental ratings against installation site conditions such as temperature and exposure to contaminants.

Selection Notes

Select this model when a compact retro-reflective sensor with light curtain functionality is required. Ensure the sensing range meets the application distance needs. Verify power supply voltage compatibility and confirm that the switching frequency is sufficient for the target throughput speed.

Part Context

This component belongs to the SICK LE 20 series of photoelectric sensors. The series is characterized by its compact design and versatility in various industrial settings.
