Beam sensor

Begin by deciding between wired and wireless configurations, then check the supply voltage compatibility and the type of output. Wired options commonly run on 12V AC/DC with a relay output (NO/NC) for door or gate control, while wireless models emphasize alarm compatibility and easier installation. The catalog includes wired 12V sensors for gates and doors and wireless models designed to integrate with intrusion alarms, giving you options based on installation complexity and control needs.

The most complex attribute is how voltage range and output interfaces match your control system. Some sensors operate at 12V AC/DC with a relay NO/NC output, while wireless variants specify a broad input voltage range and compatibility with alarm functionality. Understanding whether your existing door controller or alarm panel expects a digital signal, a relay contact, or a wireless link helps you pick a sensor that communicates reliably with your system.

For fixed, high‑reliability setups, a wired beam sensor with a NO/NC relay is ideal because it delivers a direct, robust control signal to the gate mechanism. If you need easier relocation or non‑invasive installation, a wireless infrared beam sensor offers flexible placement and simpler integration with alarm functionality, reducing wiring runs while maintaining security coverage.

Install beams at points where the protected area can be clearly monitored, such as gate or door openings, with a clear line of sight between emitter and receiver. For external gates, choose devices with robust mounting hardware and secure cable routing to avoid interference. The best sensors are those designed for automatic gate or door applications and can switch the connected control system reliably without false triggers.

Wired sensors typically require a 12V AC/DC supply and provide a relay output (NO/NC) for direct integration with controllers. Wireless sensors rely on their own signaling protocols and are designed to connect with alarm or security systems without hard wiring. Some modules in the broader beam family offer Arduino‑friendly interfaces or TTL outputs, expanding compatibility with DIY automation and microcontroller projects.

Yes. Some beam-related modules are designed for Arduino-like platforms, offering straightforward VCC, GND, and OUT connections. These modules enable speed sensing, counting, and basic motion detection in DIY robotics and automation projects, allowing you to read beam interruptions directly with microcontrollers and trigger custom responses in your code.
