The SICK HL18-B1E3BB (part number 1088137) is a high-performance photoelectric sensor designed to provide precise object detection in industrial environments. Utilizing the retro-reflective principle with a dual lens system, this sensor is capable of detecting objects at distances up to 6.5‚ÄØm, ensuring reliable operation even in demanding conditions.

Sensing Principle and Performance

The HL18-B1E3BB operates in retro-reflective mode, meaning the emitter and receiver are combined into a single unit and a reflector is placed opposite the sensor. When an object interrupts the light beam between the sensor and the reflector, the sensor detects its presence. This configuration allows for accurate detection with minimal interference from background surfaces. The visible red LED light source not only enhances visibility but also simplifies alignment during installation. With a high switching frequency of up to 1,000‚ÄØHz and a rapid response time, the sensor is suitable for high-speed applications, where fast and reliable object detection is critical.

Electrical Specifications

This sensor operates within a supply voltage range of 10 V DC to 30 V DC and features both PNP and NPN outputs with a maximum output current of 100 mA. The light/dark switching mode can be selected via a built-in potentiometer, providing flexibility for different application needs. The sensor’s output signals are compatible with standard control systems, allowing seamless integration into automated systems.

Mechanical and Environmental Characteristics

The HL18-B1E3BB is housed in a robust plastic enclosure that offers IP67 and IP69K ratings, protecting it against dust, water, and high-pressure cleaning. Its compact design, with dimensions suitable for space-constrained installations, ensures easy integration into existing machinery and automation setups. The sensor is engineered for long-term reliability and consistent performance, even under harsh industrial conditions.

Applications

This sensor 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 product positioning during packaging processes.

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

Access control: Detecting unauthorized access or movement in restricted areas.

With its long sensing range, high switching frequency, and durable housing, the SICK HL18-B1E3BB is an excellent choice for enhancing precision, reliability, and efficiency in industrial automation processes.
