This 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 suitable for photoelectric counting, security, ultra-high vehicle overrun detection etc. Specification * Voltage: 5VDC * Power(Emitter): 30mW * Interface of the receiver: Digital * Directly support Arduino processor * Pointing Angle: 3℃ * Corresponding Time: <5ms * Detection Range: 65M (2559") * Protection grade: IP66 * Size: 65*M18 (mm) Documents * Wiki Shipping List * Laser Emitter(With Wires) ×1 * Laser Receptor(With Wires) ×1 https://elecena.pl/product/22714529/laser-photoelectric-switch-gab100m-ak-5v-discontinued 2023-03-06 https://elecena.pl/product/22714529/laser-photoelectric-switch-gab100m-ak-5v-discontinued 2024-09-19
