Inside the datasheet the reader can find information regarding beam sensor, collimated beam sensor, and resistance. The datasheet gives the reader discussion related to circuit diagram, measurement, and laser sensor.
Lots of explanation around laser, laser beam, and response time are explained in the datasheet. These are some excerpt from the datasheet:
Laser Collimated Beam Sensor ‘Class 1’ Laser Beam Sensor Safe for Your Eyes Marked Conforming to EMC Directive (Excluding LA-C1) Safe Laser Beam Precise Sensing in Wide Area Easy Laser Beam Alignment This laser collimated beam sensor conforms to the Class 1 laser stipulated in IEC Publication 825 and JIS C 6802. Hence, safety measures such as protective gear are not necessary. Sensing area: 15 500mm Minimum sensing object: “0.1mm Repeatability: 10!m or less Four monitoring LEDs help you to easily align the emitter and the receiver.
Furthermore, this datasheet explains info about circuit, laser sensor controller, and sensor.
