🎯 High-Speed Precision Detection with IR Break Beam Sensor : This photoelectric switch delivers ultra-fast 2ms response time, far outperforming traditional PIR sensors for reliable, accurate motion detection without false triggers. The infrared sensor's consistent 30cm through-beam range ensures precise object detection, making it ideal for robotics speed measurement, assembly line counting, and smart device positioning where real-time feedback is critical.
🔌 Broad Compatibility for Seamless Project Integration : Our photoelectric sensors feature a wide DC 3-5V operating voltage, compatible with Arduino, STM32, 51 microcontrollers, PLCs, and relay modules. The NPN normally open output simplifies wiring, letting you connect directly to microcontroller I/O ports with just a 1K pull-up resistor, perfect for hobbyists and engineers building smart robots, industrial control systems, or educational models.
📦 Cost-Effective 4-Piece Set for Multi-Project Needs : Unlike single-unit options, this complete 4-pack of ir sensor modules delivers unbeatable value for builders needing multiple sensing points. Each split through-beam photoelectric switch comes with a 30cm/11.8inch pre-wired cable, ready to install for multi-zone motion detection, conveyor counting, or robotics competition setups, eliminating the need for repeated purchases.
⚙️ Stable, Interference-Resistant Performance : Engineered with anti-interference technology, this break beam sensor maintains consistent performance in complex electrical environments, ensuring reliable object detection for industrial control, smart home automation, and educational robotics. The compact 20108mm through-beam heads fit easily in tight spaces, with low 1mA current draw for energy-efficient operation in long-term projects.
🛠️ Versatile Applications Across Use Cases : This ir break beam sensor detects any object that interrupts the infrared beam (not just metal), making it suitable for a wide range of projects: counting inventory on production lines, triggering smart door alerts, measuring robot speed in competitions, and building educational sensing models. The easy-to-use design lets makers of all skill levels integrate reliable photoelectric switch functionality into their builds.
