SICK VTE18-4N4240 Photoelectric Proximity Sensor M18

SICK VTE18-4N4240 Photoelectric Proximity Sensor with Adjustable Detection Range

The SICK VTE18-4N4240 photoelectric proximity sensor is a compact M18 cylindrical sensor designed for reliable, non-contact object detection in industrial automation systems. It uses an energetic photoelectric operating principle with infrared LED technology to detect objects across an adjustable sensing range of up to 350 mm. This model is well suited for applications where space is limited but detection accuracy and stability are critical. With its robust metal housing and high environmental protection rating, the SICK VTE18-4N4240 addresses common challenges such as inconsistent detection, mechanical wear, and sensor failure in harsh production environments.

The SICK VTE18-4N4240 provides consistent detection performance even when object surfaces, colors, or reflectivity vary. Sensitivity can be finely adjusted during setup, allowing precise adaptation to different materials and installation conditions. Its fast response time supports high-speed automation tasks such as conveyor monitoring, part counting, and positioning control. The durable nickel-plated brass housing resists vibration, dust, and moisture, ensuring long service life. Standardized electrical connection simplifies installation and replacement, helping maintenance teams reduce downtime and keep production lines running efficiently.

Why SICK VTE18-4N4240?
The SICK VTE18-4N4240 is chosen when accuracy, durability, and flexibility must coexist in a single sensor. Its adjustable sensing range allows engineers to fine-tune detection exactly to the application, rather than adapting the machine to the sensor. Combined with fast switching, compact M18 design, and a rugged metal housing, it delivers dependable performance in fast-moving and space-constrained automation systems where reliability directly impacts productivity.

What problem does it solve?
The SICK VTE18-4N4240 eliminates unreliable object detection caused by varying surface colors, reflections, or environmental conditions. It replaces mechanical sensing methods that wear out over time with stable, non-contact detection. By offering precise adjustment and rapid response, it prevents missed counts, false triggers, and process interruptions, helping manufacturers maintain consistent quality and uninterrupted operation in demanding industrial environments.

The Applications

1. High-Speed Conveyor Item Detection in Packaging Lines

In automated packaging lines, products move at high speeds and often differ in size, shape, or surface finish. The SICK VTE18-4N4240 is used to detect items as they approach labeling, sealing, or sorting stations. Its fast response time ensures accurate triggering without missed signals, even during continuous operation. The adjustable sensing range helps engineers avoid false detection from conveyor frames or rollers behind the product. With a compact M18 housing and high environmental protection, the sensor maintains stable performance in dusty, vibrating, and production-intensive packaging environments.

2. Part Presence Verification in Automated Assembly Cells

Automated assembly processes require confirmation that each component is correctly positioned before the next operation begins. The SICK VTE18-4N4240 is applied to verify part presence in fixtures prior to pressing, fastening, or welding steps. Non-contact sensing removes mechanical wear issues associated with physical switches. Sensitivity adjustment allows reliable detection of parts with reflective or uneven surfaces. Its fast switching capability supports short machine cycle times, while the robust metal housing ensures dependable operation under constant vibration and repeated motion.

3. Pallet and Box Detection in Material Handling Systems

In material handling and intralogistics systems, reliable detection is essential for controlling pallet flow and accumulation zones. The SICK VTE18-4N4240 is used to detect boxes or pallets approaching stops, transfers, or lift mechanisms. Adjustable detection distance enables precise focus on the target while ignoring background structures. Infrared photoelectric sensing delivers consistent results across different packaging materials. The durable construction and wide operating temperature range support long-term operation in warehouses and distribution centers where dust, temperature changes, and continuous use are common.

4. Machine Position Monitoring in Industrial Equipment

Industrial machines often require accurate monitoring of moving components such as slides, covers, or transfer arms. The SICK VTE18-4N4240 is used to confirm defined positions without physical contact. Its rapid response provides immediate feedback to control systems, reducing the risk of collisions or sequence errors. The compact cylindrical design simplifies installation in confined spaces. With a metal housing resistant to oil mist and vibration, the sensor offers long service life and reduces maintenance compared to traditional mechanical position switches.
