Overview

The SICK VL18-4N3140 is a retro-reflective photoelectric sensor with an M18 cylindrical housing. It utilizes visible red light for detection and features an axial optical axis. The sensing range extends from 0.05 meters to 3.7 meters when used with the C110A reflector, or up to 3 meters with the PL80A reflector. The device has a dispersion angle of approximately 2.8 degrees and a light spot size of Ø150mm at 3 meters distance. It includes no adjustment mechanism and offers an average service life of 100,000 hours at +25°C.

Feature Summary

• Retro-reflective functional principle utilizing visible red LED light source
• Cylindrical M18x1 threaded housing design with axial optical axis
• Fixed focus configuration without manual adjustment capabilities

Applications

• Object detection in automated industrial machinery
• Presence verification in packaging systems
• Conveyor belt monitoring applications

Procurement Notes

Verify the specific part number against official SICK documentation to ensure compatibility with required reflectors such as the C110A or PL80A. Confirm that the fixed sensing range meets application requirements since the unit lacks adjustment features. Ensure the M18 mounting thread aligns with existing mechanical infrastructure before procurement.

Selection Notes

Select this model for applications requiring a compact M18 form factor with a fixed sensing range. Consider the lack of adjustment features during system design. Evaluate the need for compatible reflectors like the C110A to achieve maximum range. Verify environmental conditions against the operating temperature specifications.
