The SICK HL18-B1G3BB (part number 1088138) is a high-performance photoelectric sensor designed for precise object detection in industrial applications. Operating on the retro-reflective principle with a dual lens system, it utilizes a visible red LED light source to achieve a sensing range from 0‚ÄØm to 6.5‚ÄØm, ensuring reliable detection over extended distances.

Sensing Principle and Performance

The sensor employs a retro-reflective mode, where the emitter and receiver are integrated into a single unit, and a reflector is positioned opposite the sensor. When an object interrupts the light beam between the sensor and the reflector, the sensor detects the presence of the object. This configuration allows for high-precision detection with minimal interference from background surfaces. The visible red LED light source facilitates easy alignment during installation and ensures consistent performance. With a switching frequency of up to 1,000‚ÄØHz and a response time of 0.5 milliseconds, the HL18-B1G3BB is suitable for high-speed applications requiring rapid detection.

Electrical Specifications

Operating within a supply voltage range of 10‚ÄØV DC to 30‚ÄØV DC, the sensor features both PNP and NPN outputs with a maximum output current of 100‚ÄØmA. The light/dark switching mode can be selected via the potentiometer, offering flexibility in various detection scenarios. Signal voltage levels are compatible with standard control systems, ensuring seamless integration into automated setups.

Mechanical and Environmental Characteristics

Encased in a robust plastic housing, the HL18-B1G3BB boasts an IP67 protection rating, safeguarding it against dust and water ingress. Additionally, it is rated IP69K, providing protection against high-pressure steam and water jets, making it suitable for use in demanding industrial environments. The compact design, with dimensions of 16.2‚ÄØmm x 45.5‚ÄØmm x 31.8‚ÄØmm, allows for easy installation and integration into space-constrained applications.

Applications

The HL18-B1G3BB is ideal for a wide range of industrial applications, including:

Conveyor systems: Detecting the presence or absence of items on conveyor belts.

Packaging lines: Monitoring the position of products during packaging processes.

Material handling: Ensuring accurate placement and movement of materials in automated systems.
