1140657

Overview

The SICK model 1140657 is a VL18-4N3140 photoelectric retro-reflective sensor designed for industrial object detection. It features an M18 cylindrical housing with an axial optical axis and utilizes visible red light for operation. The device provides a maximum sensing range of up to 3.7 meters when paired with the specified C110A reflector, or up to 3 meters without it. The unit measures 18mm by 18mm by 78mm and weighs approximately 59 grams. It includes an integrated LED light source with an average service life of 100,000 hours at +25°C ambient temperature.

Feature Summary

• Retro-reflective functional principle utilizing visible red light emission
• Cylindrical M18 threaded housing design for robust mounting
• Axial optical axis configuration for precise alignment
• Adjustable focus capability to optimize detection distance

Applications

• Automated assembly line monitoring

Procurement Notes

Verify the specific ordering suffix matches the required cable length and connector type. Confirm that the application environment does not exceed the rated operating temperature limits. Ensure the correct reflector model is included in the system design to achieve the stated maximum sensing range. Check for compatibility with existing control voltage supplies.

Selection Notes

Select this model for applications requiring reliable detection of opaque objects at medium distances. The visible red light aids in visual alignment during installation. Consider the M18 form factor for standard mounting brackets. Evaluate the need for adjustable focus if the target distance varies significantly across production runs.
