Product Overview

The SB-10 Single Beam Sensor 10 Meter is an active infrared photoelectric detector designed for automatic doors, security systems, access control, gates, barriers, and industrial equipment. It consists of a transmitter and receiver that create an invisible infrared beam between them. When a person, vehicle, or object interrupts the beam, the receiver detects the interruption and activates its output for the connected control system.

The sensor operates on a 12–24V DC power supply and provides a fast response time of approximately 30 ms. With a 940 nm infrared wavelength and IP55-rated housing, it is designed for reliable operation in suitable indoor and outdoor environments. Its weather-resistant construction helps protect the sensor from dust and rain, while proper alignment ensures stable beam detection.

Main Purpose

Package Contents

• 1 × SB-10 Infrared Transmitter
• 1 × SB-10 Infrared Receiver
• Mounting Screws & Accessories – As supplied with the product
• User / Installation Manual – If included in the package

Installation

Step 1 – Select the Installation Position
Select a suitable location for the transmitter and receiver. The manual recommends an installation distance of at least 2 meters between the transmitter and receiver.

Step 2 – Maintain Correct Alignment
Install the transmitter and receiver at the same height and on the same horizontal line. The transmitter and receiver should face each other directly so that the infrared beam can travel correctly between them.

Step 3 – Avoid Direct Sunlight
Install the sensor in a position where direct sunlight does not shine into the receiver lens, as strong sunlight may interfere with infrared beam detection.

Step 4 – Prepare the Mounting Holes
Use the supplied mounting template to mark the required screw holes and cable hole on the installation surface. Drill the holes according to the mounting template.

Step 5 – Mount the Sensor Housing
Secure the sensor base firmly to the mounting surface using suitable screws and wall plugs. Pass the required cables through the cable opening.

Step 6 – Install the Internal Sensor Assembly
Position and secure the sensor assembly inside the housing, then connect the wiring according to the terminal connections shown in the manual.

Step 7 – Align and Test the Beam
Power the transmitter and receiver and adjust their positions until the infrared beam is correctly received. Confirm that the receiver indicates normal beam reception before permanently tightening the mounting screws.

Important: Keep the transmitter and receiver stable after alignment. Movement of either unit can cause incorrect or intermittent detection.

Wiring

The SB-10 Single Beam Sensor uses a wired connection between the transmitter, receiver, power supply, and the connected control system. Connect all terminals according to the markings provided on the sensor and the applicable wiring diagram.

Power: Connect a 12–24V DC power supply to the designated power terminals of the transmitter and receiver, observing the correct polarity.

Input: The receiver receives the infrared beam transmitted by the transmitter. Ensure both units are correctly aligned and have a clear line of sight.

Output: Connect the receiver's relay output to the compatible input of an automatic door controller, gate/barrier controller, alarm panel, or access-control system. Use the appropriate COM, NO, or NC contact according to the controller's requirements.

Other Connections: Keep the transmitter and receiver properly aligned and use suitable wiring for the installation. Avoid routing sensor wiring alongside high-voltage or high-interference cables where possible.

Programming

The SB-10 does not require software programming. According to the manual, configuration is performed through physical installation, beam alignment, wiring, and the NO/NC relay jumper.

Step 1 – Power the Sensor

Connect the receiver and transmitter to their required 12–24V power supply.

Step 2 – Align the Transmitter and Receiver

Position the transmitter and receiver directly opposite each other and at the same height. Adjust them until the receiver continuously receives the infrared beam.

Step 3 – Select NO or NC Output

Use the jumper provided on the receiver PCB to select the required relay output:

• NO – Normally Open
• NC – Normally Closed

Select the position that matches the input requirement of the connected door, gate, alarm, or access-control controller.

Step 4 – Test the Beam

After alignment, interrupt the infrared beam by placing an object between the transmitter and receiver. Check that the receiver changes its relay/output state.

Step 5 – Connect to the External Controller

Once the sensor operates correctly, connect the receiver's COM and output terminals to the compatible control equipment and test the complete system.

Step 6 – Secure the Installation

After successful testing, tighten the mounting screws and ensure that neither the transmitter nor receiver can move out of alignment. 

Operation

Step 1 – Power On
Supply the transmitter and receiver with the required 12–24V power. The transmitter begins emitting an infrared beam toward the receiver.

Step 2 – Normal Beam Detection
When the transmitter and receiver are correctly aligned, the receiver continuously detects the infrared beam and remains in its normal operating state.

Step 3 – Beam Interruption
When a person, vehicle, door, gate, or other object passes through and breaks the infrared beam, the receiver detects the interruption.

Step 4 – Relay Output Activation
When the beam is interrupted, the receiver changes its relay output state according to the selected NO (Normally Open) or NC (Normally Closed) configuration.

Step 5 – Connected Equipment Responds
The relay signal is sent to the connected automatic door, gate, barrier, alarm, or access-control system, which performs the action configured on that equipment.

Step 6 – Beam Restored
When the obstruction moves away and the infrared beam is restored, the receiver returns to its normal detection state and the relay output changes accordingly.
