2M Light Curtain Sensor for High-Speed & Sectional Doors | IP67 Safety System

The 2M Light Curtain is a high-precision infrared safety protection system designed for high-speed doors, sectional doors, and industrial gates. With its advanced criss-cross beam structure, IP67 waterproof housing, and intelligent self-checking technology, this light curtain ensures reliable anti-collision protection and prevents pinch-point injuries during door operation.

Built for durability and accuracy, the system integrates seamlessly into door edges, supporting door blanking functions and providing full-height safety coverage up to 1751 mm.

Key Features of the 2M Light Curtain

1. Criss-Cross Infrared Beam Detection

The light curtain uses multiple criss-cross beams to create a dense optical safety barrier.
This ensures:

• High detection sensitivity

• No blind zones

• Reliable object detection throughout the entire protection height

Suitable for high-speed industrial doors with speeds up to 0.9 m/s.

2. IP67 Waterproof & Dustproof Housing

Designed for harsh environments, the anodized aluminum housing provides:

• Full protection against water and dust

• Stable performance in warehouses, cold storage, factories, and outdoor installations

• Long service life even under vibration and door movement

3. Real-Time Self-Check System

The internal control system continuously monitors:

• Beam alignment

• Signal status

• Fault conditions

Visual LED indicators allow installers to verify power, obstruction, or alignment in real time:

• Green LED: No object detected

• Red LED: Object detected / fault indicator

4. EMI-Resistant & Short-Circuit-Proof Output

The PNP/NPN push-pull semiconductor output is designed to resist:

• Electromagnetic interference

• Voltage spikes

• Short circuits

Ensuring stable operation near motors and industrial machinery.

5. Wide Operating Range & High Ambient Light Immunity

• Detection range: 1 – 10 meters

• Ambient light resistance: up to 100,000 Lux

• Aperture angle: Tx ±10°, Rx ±20°

Performs reliably even in bright environments such as outdoor entrances or areas exposed to direct lighting.

6. Door Blanking Compatibility

Supports installation:

• With door blanking for high-speed doors

• Without door blanking for static sectional doors

Preventing false detections caused by door panel movement.

Applications

The 2M Light Curtain is ideal for:

• High-speed roll-up doors

• Sectional overhead doors

• Industrial sliding doors

• Dock shelters
