Infrared Beam Sensor Kit for Automatic Doors and Security Systems

This infrared beam sensor kit is designed for automatic door control, access systems, safety detection and security applications.

The kit includes two parts: a transmitter and a receiver. The transmitter sends an invisible infrared beam to the receiver. When a person, vehicle or object interrupts the beam, the receiver activates its relay output.

This signal can be connected to an automatic door controller, gate controller, alarm panel or other compatible automation system.

How It Works

The transmitter and receiver are installed facing each other.

Under normal conditions, the infrared beam remains connected. When the beam is blocked, the receiver changes its relay state and sends a trigger signal to the connected controller.

Depending on the application, this can be used to:

Open or close an automatic door
Prevent a door or gate from closing
Trigger a security alarm
Detect movement across an entrance
Activate another automation device

Key Features

Separate infrared transmitter and receiver
Suitable for automatic doors, gates and security systems
Fast detection response of approximately 30 ms
Up to 10 meters outdoor operating range
Up to 20 meters indoor operating range
Operates on 12–24V
C-type changeover relay output
Adjustable beam-interruption response time
High-quality PC enclosure
Rain-cover design for outdoor installation
Built-in lightning-protection circuit
Low-power operating design

Strong Light Protection

The sensor includes an automatic strong-light filtering system and supports anti-glare protection up to approximately 50,000 lux.

This helps reduce false triggering caused by:

Direct sunlight
Vehicle headlights
Strong artificial lighting
Reflections from surrounding surfaces

Reliable Performance in Difficult Weather

The sensor is designed to operate in outdoor conditions such as:

Fog
Rain
Dust
High humidity
Changing light conditions

Its automatic gain-control circuit increases sensitivity during heavy fog or poor weather to help maintain reliable beam detection.
