performance infrared beam Transmitter and receiver pair create a stable, invisible infrared beam up to 20 meters. When the beam is interrupted, the relay emits a switching signal. Advanced security technology Enhanced protection and safety for your site. When the infrared beam is interrupted, the gate automatically stops to protect your safety and property. Easy installation and alarm function Install each sensor opposite each other to form an infrared monitoring zone between the detectors. When someone crosses the zone, the detector sends an alarm signal. Versatile compatibility and applications Compatible with all gate openers. Suitable for use in various areas such as access control systems and parking lots. Ideal for security in schools, office buildings, and private grounds. Use scenarios Residential or multitenant gates: Integrates with gate operators to halt movement if the beam is breached, reducing injury risk and property damage. Parking facility entrances: Pairs with access control to monitor vehicle entry, trigger alarms, and prevent unauthorized access. School, office, and private premises security: Protects restricted entry points by creating a reliable infrared monitoring zone between detectors.
