WT18-3P431

The SICK WT18-3P431 is a compact photoelectric sensor used primarily for detecting objects and material presence in manufacturing and logistics environments. It uses light to detect the presence of objects, with a range of operational modes (e.g., diffuse, retro-reflective, or through-beam) depending on the specific application. The sensor is designed to be highly reliable and durable, even in harsh industrial conditions.

Key Parameters:

Type of Sensor:

Photoelectric sensor (diffuse, retro-reflective, or through-beam modes, depending on the variant).

Detection Range:

Up to 4 meters depending on the object and reflective properties. For diffuse models, the range is typically shorter.

Output:

Digital output: Standard PNP or NPN output (depending on the specific model configuration).

Switching Output: The sensor provides a reliable switching output when the detected object passes the detection zone, triggering a signal in the control system.

Light-on or Dark-on operation mode: Can be configured to respond to either the presence of light or the absence of light.

Response Time:

Fast response time of < 1 ms for rapid detection in high-speed applications.

Power Supply:

Standard 10-30 VDC supply, ensuring compatibility with most industrial control systems and automation setups.

Protection Class:

IP67 protection rating, meaning the sensor is fully protected against dust ingress and can withstand water immersion up to a certain depth, making it ideal for use in harsh environments.

Temperature Range:

-25°C to +60°C operating temperature range, making it suitable for a variety of environments, including those with temperature fluctuations.

Sensing Angle:

The sensor has a wide detection angle of up to 30°, ensuring that it can detect objects at a larger range.

Housing:

Compact and rugged metal housing designed to withstand shocks, vibrations, and mechanical stress common in industrial settings.

Laser Class:

The sensor typically uses a Class 1 LED light source, which is eye-safe during normal operation.

Mounting:

Easy installation with various mounting options. The sensor is designed to be mounted in a fixed position to detect objects passing through its field of view.

Applications:

Object detection in conveyor systems for sorting or material handling.

Presence sensing to detect products or parts on automated production lines.

Automation of assembly lines by detecting the presence or absence of objects, allowing for real-time control of manufacturing processes.

Packaging and logistics to monitor items as they move through various processing stages.
