Sensor Beam | 10m / 30ft Detection Range | Automatic Door Safety

This dual beam photoelectric sensor gives reliable object detection for automatic doors, gates, and security systems. It creates an invisible infrared barrier up to 10 meters (about 30 feet) long. If an object breaks both beams, the sensor sends a signal to stop or reverse motion. Features and Benefits - Dual infrared beams - Reduces false alarms from falling leaves or rain, since both beams must be broken at the same time to trigger. - IP55 weatherproof housing - The sealed enclosure protects the internal electronics from dust and water spray, making it suitable for outdoor use. - Wide alignment angle - The transmitter and receiver can rotate 180° horizontally, simplifying installation and aiming. - NO/NC relay output - Offers flexible wiring options to integrate with almost any automatic door, sliding gate opener, or alarm system. Applications - Automatic Sliding Gates: Stops the gate from closing on a vehicle or person by detecting their presence in the pathway. - Garage Door Safety: Adds a layer of safety by stopping the door from closing if a child, pet, or object is in the way. - Perimeter Security: Works as a tripwire for an alarm system to detect intruders crossing a property line or walkway. How They Work Photoelectric sensors, also known as optical sensors or light sensors, operate by emitting a light beam and detecting changes in the reflected or interrupted light. For this Sensor Beam, the single dual white beams are used to detect objects within its 10m detection range. When an object breaks or reflects the beam, the sensor triggers a response, such as opening or closing an automatic door. This process happens quickly, with a response time of less than 30ms. 3 Main Types of Photoelectric Sensors There are three primary types of photoelectric sensors. Through-beam sensors have separate emitter and receiver units, detecting an object when the beam between them is broken. Retro-reflective sensors combine the emitter and receiver in one unit and use a reflector to bounce the light back. Diffuse-reflective sensors also have the emitter and receiver in one unit but detect light directly reflected off the target object itself. Common Applications Photoelectric sensors are widely used in industrial and commercial settings for various detection tasks. For this specific Sensor Beam, the primary application is for automatic doors. This means it is designed to detect the presence of people or objects approaching or in the path of a door, ensuring safe and efficient operation. Other common uses include counting items on a conveyor belt, position sensing, and security systems. The Core Components A photoelectric sensor, like this Sensor Beam, comprises several key components. It includes a light emitter, typically an LED, which sends out the light beam. A light receiver, often a phototransistor or photodiode, detects the emitted light. The sensor also has internal processing circuitry to interpret the received light and trigger an output. These components work together to provide reliable detection within the 10m range. The 3 Main Operating Modes Photoelectric sensors generally operate in three main modes. The "dark-on" mode means the output is activated when the light beam is interrupted or blocked. Conversely, "light-on" mode activates the output when the sensor detects light. Some sensors offer a selectable mode, allowing the user to choose between dark-on and light-on operation depending on the application requirements. This Sensor Beam is designed for auto-door applications.
