ELECTRICAL INTERFACE

- Power Supply Voltage: DC 22V-34V

- Average Power Consumption: ≤ 10W

- The laser rangefinder utilizes a J30-9ZK connector receptacle, which integrates both the power supply for the rangefinder and communication signals. It employs a standard RS422 communication interface for data exchange with the host system. The corresponding plug connector on the system side is model J30-9TJ. The pinout definitions for these connectors are as detailed in the accompanying Table 2.
