💡 What is a through-beam break beam sensor used for in automation projects?

Here's a handy, concise answer.

• High accuracy object detection across a 50 cm gap for conveyors and robotics
• Easy integration with Arduino, STM32, PLCs for counting, timing, or motion sensing
• Low-voltage operation (3-5 V) and NPN normally open output simplify wiring
• Fast 2 ms response improves timing and reduces missed detections
