Product Description

JUTAI 1.8m 29-Beam Safety Blanking Light Curtain Sensor

The JUTAI 1.8m 29-Beam Safety Blanking Light Curtain Sensor is an advanced safety device designed to meet a wide range of industrial and commercial safety requirements. It combines high-quality components and sophisticated features to deliver reliable and efficient protection in critical areas.

1. Special Features

• Seamless Installation: The light curtain is designed for easy integration into door gaps, ensuring it does not interfere with the normal closing process. This feature offers convenience and practical installation.
• Sunlight Tested: Proven to operate without interference from strong sunlight, the sensor remains reliable in both bright outdoor and well-lit indoor environments.
• High-Quality Components: Made with imported lamp cores, the sensor offers exceptional anti-light performance, enhancing durability and product longevity.

2. Product Function

The JUTAI 1.8m 29-Beam Safety Blanking Light Curtain Sensor creates a protective grid by emitting 29 straight infrared light beams between the transmitter and receiver. If an object or person enters the detection area, the system immediately activates safety measures. A unique Blanking Function ensures that irrelevant objects are ignored, maintaining optimal sensor performance without interference from unnecessary obstructions. This function makes the sensor ideal for use in critical areas such as doors, automated gate, and elevating equipment, effectively mitigating potential entrapment risks.

3. Blanking Function

• Install: The light curtain is installed inside the door gap.
• Close: As the door closes, the light beams are sequentially blocked from top to bottom. The system interprets this sequence as a normal door closure.
• Detect: If an object interrupts the light beam during the door's closing motion, the system immediately triggers the door to reopen, ensuring safety.

4. Size and Dimensions

• Length: Suitable for a variety of installations, the sensor measures 1838mm in total length, fitting seamlessly into door gaps.
• Cross-Section: With a slim design and a cross-section of 12.5mm, it fits perfectly in narrow spaces without obstructing door movements.
• Beam Distance: The beam distance is precisely set at 60mm, ensuring the detection of even small objects, such as forklift forks, with high accuracy.

7. Troubleshooting

• Light Curtains Not Lined Up:

  • Power cycle both units.
  • Check synchronization wiring.
  • Reinstall if position is unstable.

• Signal Light On but No Blockage:

  • Ensure no other infrared devices are interfering.
  • Clean the light curtain to remove any obstructions.
  • Adjust alignment between transmitter and receiver.

• No Anti-Pinch Action:

  • Check relay output and anti-pinch connections.
  • Ensure the working distance is within the specified range.

• Unable to Access the Hide Function:

  • Check for light leakage during operation.
  • Ensure that the bottom beam is not blocked.
  • Verify that the door or shelter meets minimum distance requirements for continuous shielding.

8. Cautions

• Keep the connecting cables away from high-voltage or high-current conductors to prevent interference.
• Ensure that the lower door or shelter used for the blanking function is correctly positioned to meet required conditions.
• Regularly clean the transmitter and receiver windows with a soft towel to avoid dirt buildup, which may affect sensor operation.
• Avoid bending or twisting the light curtain to maintain its integrity.
• Conduct monthly checks for looseness in the transmitter, receiver, and extension cord, as well as the reliability of the wiring connections.
