SICK WL4S-3P3430V Retroreflective Photoelectric Sensor block sensor features a 4 m detection range, PNP output, and robust stainless steel housing designed for industrial and automation applications. This sensor combines advanced ASIC and PinPoint LED technology to detect all object types, including transparent and shiny materials such as blister packs, e-cards, and aluminum cans with high reliability.
The sensor provides background suppression with a laser-like light spot for precise measurements, reducing additional protective measures and enabling efficient machine integration through its slim design and optical axis on a flat side. Its robust ingress protection rated IP66 through IP69K safeguards operation in harsh environmental conditions.
Equipped with a 4-pin M12 connector, the sensor offers convenient installation and integration with industrial control systems. Its fast 500 microseconds response time and high current rating of 100mA support rapid automation processes and reliable object detection.
The device accommodates flexible sensor settings, including 5-turn potentiometer adjustments, teach-in pushbutton, cable teach-in, and optional IO-Link interface for enhanced monitoring, diagnostics, and visualization of sensor data within automation platforms.
Common industrial applications include secondary packaging detection, presence and level monitoring on conveyor belts and vibratory bowl feeders, as well as access protection with muting functions on belt conveyors.
Operates reliably between -30°C and 60°C for versatile environment compatibility. PinPoint LED light source enhances accuracy for transparent or reflective objects. Stainless steel housing with screw mount assures durable and maintenance-free installation.
Certified to EN IEC 60947-5-2 and EN IEC 63000 for industrial electrical safety compliance. Designed and manufactured in Germany, ensuring quality and precision.
