SICK HTB18-A4A2BB Photoelectric Sensor

HTB18-A4A2BB is a 300 mm sensing-range photoelectric sensor from SICK's H18 Sure Sense family, designed for reliable non-contact object detection in industrial environments. It runs from a 10 to 30 V DC supply and uses a 4-pin M12 connector for easy wiring. The unit supports both NPN and PNP output configurations and includes background suppression to differentiate targets from background clutter. Known also as 1073426, the HTB18-A4A2BB is part of the H18 Sure Sense lineup and offers a compact package suitable for mounting on conveyors, machinery, and automation assemblies where stable detection is needed in backgrounds with potentially interfering objects.
