Equipped with a 1535nm laser source, the ERDI LRF0405C complies with Class I eye-safety standards, balancing long-range detection capabilities with operational safety. The module offers a measurement range of 15 to 5,000 meters, achieving stable detection of a standard 2.3m × 2.3m target at 4,000 meters with an accuracy exceeding 98%; it supports the simultaneous identification of up to three targets and can distinguish between signals from near and far targets.
The hardware features an ultra-compact design, measuring 48 × 30.5 × 21 mm and weighing just 32 g, making it suitable for integration into various small-scale devices. It operates reliably across a wide temperature range—from -40°C to +70°C—and offers shock and water resistance, ensuring suitability for demanding outdoor industrial environments. Equipped with a TTL serial interface, it supports both single and continuous ranging modes with adjustable frequencies, and includes built-in self-test and temperature monitoring capabilities. Thanks to its compact size and reliability, it is widely used in applications such as drone-mounted optoelectronic pods, perimeter security patrols, and portable observation equipment.
