SICK VTE18-4N2240 Infrared Photoelectric Proximity Sensor

The Applications

1. Precision Part Presence Detection on Automated Assembly Lines

Automated assembly equipment requires confirmation that each component is correctly positioned before the next operation starts. The SICK VTE18-4N2240 can be installed close to the working area to detect small metal or plastic parts just prior to fastening or pressing. Its energetic photoelectric sensing allows direct detection without additional reflectors, which is valuable in compact machine designs. The focused infrared beam supports accurate sensing when parts are close together, while fast switching enables use on high-speed lines. Adjustable sensitivity helps maintain reliable detection despite changes in surface finish or color, reducing assembly faults.

2. Conveyor-Based Product Flow Monitoring in Packaging Systems

Packaging and material handling lines depend on stable product flow to prevent jams and downtime. The VTE18-4N2240 can be mounted along conveyor frames to monitor the presence of cartons, trays, or wrapped goods at critical checkpoints. Its compact M18 form factor simplifies integration into narrow conveyor structures. The metal housing tolerates vibration and continuous operation, while selectable light or dark switching allows adaptation to different conveyor surfaces. Consistent short-range detection helps ensure smooth product movement and supports early intervention before line disruptions occur.

3. Position Verification in Pneumatic and Mechanical Actuators

Machines that use pneumatic or mechanical actuators often require precise confirmation of end positions for safe and repeatable motion. The SICK VTE18-4N2240 provides non-contact position verification by detecting actuator components without physical wear. The infrared sensing principle enables accurate detection even in tight installation spaces. Fast response time supports precise timing within control sequences, and the standard electrical interface integrates easily with PLC systems. By eliminating mechanical contact, the sensor reduces maintenance requirements and improves long-term reliability in repetitive motion applications.

4. Reliable Object Detection in Harsh Industrial Environments

Manufacturing environments with dust, oil mist, or temperature changes place high demands on sensing equipment. The VTE18-4N2240 is suitable for detecting workpieces, carriers, or fixtures in such conditions due to its sealed construction and durable metal body. Infrared detection maintains stable performance despite ambient light variations, and sensitivity adjustment allows tuning for different materials. This combination supports consistent operation over long periods, helping maintain process stability and reducing unplanned downtime caused by sensor failures.
