905nm laser ranging distance sensor 1200m

Model: LRF1200A2-01
The LRF1200A2 is a professional-grade 905nm laser rangefinder module designed for precision and durability in demanding applications. With a Class 1 eye-safe rating and ≤6mrad divergence, it delivers accurate measurements from 5m to 1200m (on a 3m x 3m target) with 0.1m display resolution and ≥98% reliability. The compact Φ25mm × 40mm housing (≤18g) integrates seamlessly into systems, while its -20°C to +55°C operating range and IP67-rated head ensure resilience in harsh environments. Featuring low power consumption (≤1W operating, ≤400mW standby), UART (TTL 3.3V) interface, and CE/FCC/RoHS2.0 compliance, it excels in industrial automation, robotics, and surveying. Additional ruggedness comes from 1200g impact resistance, 1000g/ms anti-vibration, and 6kV/8kV ESD protection, making it a reliable choice for critical operations.

LRF1200A2 laser rangfinder module is a new lightweight and compact ranging module, operating at a wavelength of 905nm. The maximum range of the product is ≥1200m, using a UART-TTL interface and supporting test software, which is convenient for users to further develop. This laser  rangefinder module has the characteristics of small size, light weight and reliable performance. It can be used in aviation, communications, geology, police, outdoor sports and other occasions.
