5km Industrial-Grade Laser Distance Sensor 38400bps Class 1 Compact Outdoor Laser Rangefinder Module with RS422 Serial Interface

The industrial-grade 5km laser rangefinder module(model: ETYS-50X), configured to a 38400bps baud rate with an RS422 interface and 1535nm Class 1 eye-safe compliance represents a highly specialized category of long-range electro-optical hardware. These range finder sensor modules are engineered primarily for security applications, UAV/UGV drone payloads, and maritime patrol tracking systems. 

Core Architecture and Hardware Features

At a 5,000-meter range baseline, manufacturers utilize 1535nm Erbium-glass solid-state lasers. This wavelength operates safely within the Class 1 human eye-safety threshold while delivering enough energy to punch through atmospheric noise. 

Communication Stack: Features a differential RS422 serial protocol for long-distance, high-noise data immunity. The factory default baud rate is hardcoded to 38400 bps, transmitting with a standard byte frame architecture: 1 start bit, 8 data bits, no parity, and 1 stop bit. 

Target Dynamics: Typically rated for 5,000 meters against standard NATO targets (2.3m x 2.3m vehicles) and up to 7,700 meters against high-reflectivity targets like buildings, if person up to 3,000m. 

Form Factor: Optimized (Size, Weight, and Power) for lightweight aerial integration. Modules typically weigh between 75g to 85g with compact outer dimensions (e.g., approximately 62mm×43mm×32mm).
