Product overview
The ERDILRF SPD1200D03 is a 905 nm laser rangefinder module designed for integration into OEM equipment. Its body measures 10.7 × 16.8 × 22 mm, with a UART interface using TTL 3.3 V signaling and a supply voltage of 3.3–5 V. The module provides an adaptive measurement frequency of 2–15 Hz. Each module is assembled, aligned, calibrated and accepted in-house in Chengdu.
The SPD1200D03 provides a maximum range of ≥1,200 m against a building target with 70% reflectivity when visibility is ≥6 km. Its minimum range is 0.2 m against a 90% reflectivity whiteboard. Ranging accuracy is ±0.3 m at distances ≤100 m and ±(0.4 + 0.006×D) m at distances greater than 100 m.
