1141934

Overview

The SICK model 1141934 is a VL18 series retro-reflective photoelectric sensor designed for industrial object detection. It features an M18 cylindrical housing with a sensing range of up to 3 meters when used with the specified reflector. The device utilizes visible red light emission and operates on a DC 3-wire connection interface. Key technical specifications include a light spot size of approximately 150mm at maximum distance, a dispersion angle of roughly 2.8 degrees, and an average LED service life of 100,000 hours under standard conditions. The unit weighs 59 grams and originates from Italy.

Procurement Notes

Verify the part number 1141934 against official SICK documentation to ensure compatibility with required voltage levels and switching outputs. Confirm that the necessary accessories, such as the C110A reflector, are included or ordered separately. Check for regional certification requirements and environmental ratings relevant to the installation site before finalizing procurement.

Selection Notes

Select this sensor when a compact form factor and moderate sensing range are required. Ensure the application environment supports the use of retro-reflective technology and that ambient light conditions do not interfere with the visible red spectrum. Verify mechanical mounting constraints align with the M18 thread diameter and housing dimensions.

Part Context

This component belongs to the SICK VL18 series of photoelectric sensors, which are engineered for general-purpose industrial detection tasks. The series emphasizes durability and ease of integration into automated systems. The VL18 models are widely utilized in manufacturing environments where precise positioning and reliable signal transmission are critical for operational efficiency.

Replacement Considerations

Consult official SICK cross-reference guides for direct replacements. Ensure substitute models match the M18 housing size, electrical interface, and sensing range specifications to maintain system compatibility without requiring mechanical modifications.
