Product information

Description

The Delock U-type slot photoelectric sensor is a high-precision component engineered for reliable object detection in industrial automation environments. Featuring a 5 mm slot width, this sensor utilizes an infrared light beam to detect objects passing through the gap. It is equipped with an NPN output and offers the flexibility of selectable light-on or dark-on switching modes, allowing for versatile integration into various control systems. The unit is supplied with a durable 2-meter cable with open ends, facilitating straightforward installation and connection to existing machinery.

Advantages

This photoelectric sensor provides exceptional accuracy for high-speed detection tasks, ensuring consistent performance in demanding industrial settings. The U-shaped design allows for easy mounting and alignment, while the selectable switching modes provide the flexibility needed to adapt to different logic requirements in automation circuits. Its robust construction ensures longevity, and the integrated cable simplifies the wiring process, reducing the time required for setup and maintenance.

Suitable for

  • Object counting on conveyor belts
  • Position sensing in mechanical assemblies
  • Limit detection for moving parts
  • Edge detection for thin materials

This sensor may not be suitable for detecting transparent or highly reflective objects, as these materials can interfere with the infrared beam. Additionally, it is not intended for outdoor use in environments with high levels of ambient sunlight or extreme weather conditions, as these factors may cause false triggering or signal degradation.

Key specifications

  • Slot width: 5 mm
  • Output type: NPN
  • Switching mode: Selectable light-on or dark-on
  • Cable length: 2 meters
  • Connection: Open cable ends

To use the sensor, mount it securely so that the object to be detected passes through the 5 mm slot. Connect the wires according to the technical documentation, ensuring the power supply matches the specified voltage requirements. Once powered, select the desired switching mode using the integrated controls to match your system's logic. Ensure the sensor is kept clean and free from dust or debris to maintain optimal detection accuracy.

What to consider before purchase

  • Verify that the 5 mm slot width is sufficient for the objects you intend to detect.
  • Ensure your control system is compatible with NPN output signals.
  • Check that the 2-meter cable length is adequate for your installation layout.
  • Confirm the environmental conditions are free from excessive dust or intense ambient light.
Usage recommendations: Regularly inspect the optical surfaces of the slot to ensure they remain free of dust, oil, or other contaminants. Clean the sensor periodically with a soft, dry cloth to prevent signal interference and maintain consistent detection performance.
