Multi-Beam Safety Sensor for Door Systems with NO/NC Output & Quick Response

The JUTAI CL20-8L Multi-Beam Safety Sensor is a professional protective device engineered for door systems, featuring 8-beam detection, configurable NO/NC output, and rapid response performance. It forms an invisible light grid between the emitter and receiver, instantly triggering door reversal or stopping when personnel, hands, or objects intrude—effectively preventing pinching and crushing accidents in industrial, commercial, and logistics door scenarios. With IP67 protection and aluminum alloy housing, it delivers reliable safety保障 for fast doors, roller shutter doors, and automatic doors.

• Multi-Beam Full-Coverage Detection: 8-beam light grid eliminates safety blind spots across the entire door opening height (1729mm), ensuring no missed detection of small objects, hands, or limbs. Dense beam distribution adapts to the dynamic operation of door systems, providing all-around anti-pinch protection.
• Configurable NO/NC Output: Default NO output meets standard door control system requirements; NC output is configurable via simple operation. Flexible output mode switching allows seamless integration with various door control panels and safety relays, enhancing compatibility.
• Rapid Response for Door Safety: Instantly triggers safety actions (door reversal/stopping) upon beam interruption, matching the fast operation of high-speed doors and roller shutters. Eliminates safety lags in high-traffic door scenarios, effectively avoiding pinching accidents.
• Rugged & Reliable Performance: IP67 protection withstands dust, water splashes, and temporary immersion, suitable for indoor/outdoor door installations and harsh industrial environments. Aluminum alloy housing resists corrosion, mechanical wear, and vibration, ensuring long-term stability for frequent door operations.
• Blanking Mode for False Alarm Prevention: Blocking the first channel of the light grid does not trigger safety responses, adapting to door gap structures and sequential beam blocking during normal closure. Avoids unnecessary door interruptions while retaining full protection against unintended intrusions.

1. Complete wiring according to the Wiring Guide and confirm no connection errors.
2. Power on the sensor (ensure power supply meets DC12-24V requirements).
3. Within 1 minute of power-on, touch the receiver's Green wire (NO output) to its Black wire (GND) five consecutive times.
4. Observe the receiver's Red light blinking rapidly—this indicates successful activation: Yellow wire switches to NC mode, and Blanking Mode is enabled.

• Industrial fast doors (manufacturing plants, logistics centers)
• Roller shutter doors (warehouses, retail stores, commercial buildings)
• Automatic doors (office buildings, shopping malls, industrial workshops)
• Cold storage doors (refrigerated warehouses, freezer rooms)
• Garage doors (residential, commercial parking facilities)

• Keep connecting cables away from high-voltage/high-current conductors, door machinery, and forklift paths to avoid interference, extrusion, or damage.
• Regularly wipe the emitter and receiver lenses with a dry, soft cloth to remove dust, oil stains, or condensation—dirty lenses will affect detection accuracy.
• Do not bend, twist, or pull the sensor or cables forcefully; avoid scratching the aluminum alloy housing or infrared lenses.
• Prevent direct sunlight or other infrared light sources from shining on the receiver (avoids false triggers or detection failure).
• Ensure the door or obstruction used for Blanking Mode meets the minimum continuous blocking distance requirement.
• Periodically test the anti-pinch function and output mode to ensure the sensor works normally with the door system.
