Voltage: 5VDC
Composed of Emitter and Receptor
Power (Emitter): 30mW
Detection Range: 65M

The 5V 30mW Laser Photoelectric Switch 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 conducts. It can be directly compatible with Arduino to develop related products. Of course, it is also very suitable for photoelectric counting, security, ultra-high vehicle overrun detection etc.

Wiring:

Blue: Ground
Brown: 5VDC
Black: digital signal (receptor only)

Eye Hazzard

This product is a Class IIIB laser, but does not have any labeling or warnings to tell you that. Even a split second of direct contact with your eye can cause permanent damage, as well as direct reflections off shiny surfaces. Apart from that, the sensor works well. Although the power supply is 5V, the output is actually 3V PNP which means it cannot be used directly as an Arduino input, so I am using it to activate a relay instead.
