SICK HL18-P4A2BK Suresense Photoelectric Sensor

SICK HL18-P4A2BK SureSense is a compact M18-housing, retroreflective photoelectric sensor from the H18 Sure Sense family, combining a hybrid sensing design with a PNP output and a 4‑pin M12 connector for easy wiring from a 10–30 V DC supply. In retroreflective mode it targets reliable detection at distances up to 6.5 meters when paired with a compatible reflector (PL80A), making it suitable for line-side object presence on conveyors and packaging workflows. The device uses a visible red light (631 nm) with a PinPoint LED source to enhance detection under common ambient lighting, and it carries the part number 1071462. This model is designed for robust industrial use and integrates with standard SICK automation ecosystems, delivering dependable sensing performance across typical manufacturing environments.
