SICK VTE18-3F4112 Infrared Photoelectric Sensor M18

The Applications

1. Reliable Box and Parcel Presence Detection
In automated conveyor systems, consistent object detection is essential to avoid collisions, misrouting, or stoppages. The SICK VTE18-3F4112 is commonly installed along conveyor frames to detect cartons and parcels moving at different speeds. Its fast response time allows the control system to distinguish closely spaced items, while the non-contact infrared sensing principle prevents mechanical wear. The compact M18 metal housing fits easily into confined spaces, and the IP67 protection ensures dependable operation in dusty packaging environments, supporting smooth material flow and higher overall system uptime.

2. Accurate Product Position Monitoring
Packaging machines rely on precise timing to seal, cut, or label products correctly. This sensor is used to confirm product presence before critical actions occur. Its fixed optical configuration eliminates frequent readjustment, which is particularly useful during frequent format changes. Infrared detection maintains stable performance even when packaging materials vary in color or surface finish. With its compact cylindrical design and rapid switching capability, the VTE18-3F4112 helps maintain consistent packaging quality while reducing setup effort and minimizing operator intervention.

3. Component Presence Verification
In automated assembly processes, verifying that components are present before the next operation prevents costly errors. The VTE18-3F4112 provides reliable non-contact detection of parts such as housings or subassemblies without risking surface damage. Its fast switching speed supports short cycle times, while the rugged metal construction resists vibration from surrounding equipment. By delivering consistent detection signals, the sensor helps reduce scrap, prevent incomplete assemblies, and ensure that downstream processes only proceed when components are correctly positioned.

4. Reliable Detection in Dusty or Washdown Areas
Material handling systems in demanding environments often face dust, moisture, or frequent cleaning. The IP67-rated housing of the VTE18-3F4112 protects internal components from contaminants, enabling long-term reliable operation. Infrared sensing provides stable detection of containers, pallets, or carriers even when ambient conditions change. This makes the sensor suitable for monitoring accumulation zones, transfer points, or lift positions, helping operators maintain safe, continuous operation while reducing maintenance needs and unexpected sensor failures.
