The 45-degree cone angle window is maximized to provide a wide coverage of radiation area for detection objects in a wide range of industrial applications. The control box integrates DB9 button, power socket and indicator light for easy operation, and uses serial port to connect digital communication, which has high reliability and meanwhile also has imperceptible responsiveness. The large KV value realizes super penetrating power to objects, and the excellent heat dissipation capability ensures high-power operation. The external structure considers the installation methods in various scenarios, and is truly user-friendly.
