The SICK HTB18-B4A2BCD02 (part number 1085437) is a high-performance retro-reflective photoelectric sensor designed to deliver reliable long-distance object detection in demanding industrial applications. Part of the HTB18 series, this sensor combines advanced optical technology with a robust, industrial-grade housing to ensure consistent performance in harsh environments.

One of the key strengths of the HTB18-B4A2BCD02 is its ultra-long sensing range, capable of detecting objects from as close as 50 mm up to 15 m using a retro-reflective setup. This long-range capability makes it ideal for applications such as conveyor monitoring, automated material handling, packaging lines, and warehouse logistics. The retro-reflective principle allows for reliable detection regardless of the object’s surface properties, including glossy, dark, or irregularly shaped targets, ensuring stability and precision across various use cases.

For installation and operational convenience, the sensor is equipped with a PinPoint visible red LED emitter. The clearly defined light spot simplifies alignment, while the integrated signal strength indicator provides immediate visual feedback, allowing operators to position the sensor accurately and optimize detection performance with minimal effort.

The HTB18-B4A2BCD02 features dual NPN outputs configured for both light-on and dark-on switching, offering versatile logic integration for a wide range of control systems. These outputs allow flexible response configurations depending on the specific automation requirements. The sensor also incorporates essential electrical protection features, including reverse polarity, short-circuit, and overload safeguards, ensuring reliability and longevity in industrial operations.

Mechanically, the sensor is housed in a robust M18 cylindrical body with IP67 and IP69K ratings, providing complete protection against dust, water jets, and high-pressure washdowns. Its durable construction ensures consistent performance in challenging industrial settings, including manufacturing floors, food processing areas, and outdoor environments exposed to the elements. The compact cylindrical form factor also allows easy installation in tight spaces or standard mounts.

The HTB18-B4A2BCD02 is designed for fast and accurate detection, with a response time under 1 ms, enabling it to keep pace with high-speed production lines and automated machinery. Its wide operating voltage range and efficient power consumption make it suitable for integration into diverse industrial control systems, while maintaining robust and dependable operation over time.

In summary, the HTB18-B4A2BCD02 delivers long-range detection, precise LED alignment, dual-output flexibility, and rugged industrial durability. It is an ideal solution for applications requiring high reliability, accuracy, and efficiency, including logistics, packaging, robotics, and material handling automation.
