The WY‑09B is a best‑in‑class lightweight laser ranging module from Wanyan Technology, purpose-built for OEM integration. Featuring a 905 nm eye‑safe semiconductor laser, it delivers accurate distance measurements up to 2000 m for large targets, yet maintains ultra‑compact dimensions and a feather‑light weight (≤ 14 g). Its enclosure‑free design allows direct embedding into custom housings—perfect for stealthy or space‑limited applications.

Measures from 5 m to 2000 m on large targets.

TTL serial interface for easy connection with micro-controllers and embedded platforms.

Compact dimensions of ≤ 32 × 25 × 20 mm, weighing ≤ 14 g

Operates on 3–5 V and consumes ≤ 1 W standby power; can fully shut down to zero power

RS-422 and TTL serial available for seamless host connectivity

Operates reliably between –20 °C to +60 °C
