Through our unremitting efforts, we have successfully developed a fan-shaped laser ranging obstacle avoidance sensor with wide voltage 9-30v power supply, support switching value NPN output and PNP output, support RS232, RS485 serial output and can bus output. The baud rate, device address, output mode, output speed and other functions can be set quickly through the accessory software provided by our company. It supports 68 protocol, MODBUS protocol and can bus protocol, and can realize fast connection and communication with MCU and PLC.
