Laser Photoelectric Switch GAB100M-AK-5V Shipping:4-6 Days for closed-loop speed control usingThis is a photoelectric switch that is composed of emitter and receptor. The emitter consists of a laser diode,and the laser has the characteristics of high precision, good orientation etc. The receptor consists of a photoelectric element. When receiving the laser pulse, the built in light conducting. The emitter and receptor can assemble a detector. It can be directly compatible with Arduino to develop related products. Of course, it is also very
