Compact M18 SICK VL18-4P3640 retro-reflective sensor with long 3 m range, fast 2 ms response, and IP67 durability for precise industrial object detection.
The SICK VL18-4P3640 photoelectric retro-reflective sensor is built to provide dependable long-distance object detection in a compact M18 cylindrical housing. It reaches up to 3 m operating distance with a maximum range of 3.7 m, using a bright red LED that makes alignment straightforward even in busy industrial areas. The sensor reacts quickly thanks to a fast ≤2 ms response, while the rugged housing and IP67 sealing support use in tough factory environments. With selectable light/dark switching and a polarizing filter that helps ignore shiny surfaces, this model offers consistent performance for high-speed automation tasks.
The VL18-4P3640 is designed for applications where stable detection is essential, even when targets vary in reflectivity or when ambient conditions are less than ideal. Its focused optical design and 250 Hz switching frequency allow the sensor to track fast-moving items reliably, such as on conveyor lines or automated sorting systems. The durable build handles temperatures from –25°C to +70°C, supporting deployment in both warm production floors and cooler storage areas. With short-circuit protection, a sturdy PNP output, and a 100 g lightweight body, this sensor helps reduce maintenance needs while enhancing process consistency across multiple industries.
The VL18-4P3640 stands out because it delivers long detection range, fast response, and strong resistance to harsh factory conditions—all in a compact M18 form. It offers dependable performance even around shiny surfaces, unstable lighting, or fast-moving objects. This sensor is chosen when businesses want a simple, durable, and “install-and-trust” solution for continuous automation.
This sensor solves the common challenge of inconsistent object detection in busy, reflective, or high-speed production environments. It stabilizes detection where traditional sensors struggle—such as shiny packaging, varying object colors, dusty conveyors, or rapid material flow. By ensuring reliable triggering and minimal false readings, it keeps automated processes smooth, accurate, and interruption-free.

Modern distribution centers move parcels at high speed, and inconsistent packaging surfaces often confuse ordinary sensors. The VL18-4P3640 handles this challenge by projecting a stable, narrow beam that detects boxes even when they are glossy, wrapped, or irregularly shaped. Its fast reaction time ensures each parcel is identified the moment it enters the detection zone, reducing sorting delays. The compact M18 body fits easily onto existing conveyor brackets, making installation quick. This sensor helps maintain smooth material flow during heavy-volume operations, especially when accuracy and reliability determine overall logistics efficiency.
Automated systems rely on precise information about pallet positioning, yet wooden pallets, plastic pallets, and shrink-wrapped loads can all create unreliable reflections. The VL18-4P3640 provides stable feedback despite these variations, making it suitable for busy warehouse zones. Its extended sensing distance allows placement away from moving machinery while still capturing pallet arrival and departure. The rugged build tolerates the dust, bumps, and temperature swings typical of storage facilities. By reducing false triggers and missed detections, the sensor supports smoother forklift coordination and more dependable pallet tracking across automated workflows.
Beverage lines move bottles rapidly, and transparency differences between containers can disrupt normal sensors. The VL18-4P3640 maintains consistent detection whether bottles are clear, tinted, or covered in reflective labels. Its high switching speed keeps pace with fast-moving conveyors, ensuring counts remain accurate even during peak production runs. The cylindrical housing fits neatly onto machine frames where space is limited, and the durable sealing withstands washdown conditions. This combination makes the sensor ideal for monitoring bottle flow in filling, capping, and inspection stations where precision is essential.
Automotive production involves numerous reflective metal components that can scatter light unpredictably. The VL18-4P3640 counters this with a focused optical path that identifies part presence despite shiny surfaces or fluctuating ambient light. It delivers dependable positioning signals for robotic pick-up, welding, or alignment tasks. The sensor’s sturdy construction endures exposure to oils, vibration, and heat near assembly machinery. Its quick electrical connection supports fast changeovers, helping production lines minimize downtime. By ensuring reliable verification of each component, the sensor contributes to consistent assembly quality and smoother manufacturing cycles.
