I. NLM9500A 1535nm DPSS Advanced Industrial Telemetry Core

Bridging Massive Spatial Gaps for Autonomous Networks

The NLM9500A is a precision 9.5km laser rangefinder module developed to provide objective distance data for industrial automation, surveying, and security monitoring. Operating with a Class 1 eye-safe 1535nm DPSS laser, this sensor achieves a maximum measuring range of 9500m against large structural targets, maintaining a consistent accuracy of ±1m. To support stable target acquisition, the device is configured with a ≤80m near-field blind zone and a distance resolution of ≤50m. It executes single-shot and continuous measurements (1Hz, 5Hz) with a success rate of ≥98%, specifically engineered to eliminate false values or sudden zero readings during sustained tracking. The physical architecture is highly restricted, keeping the overall mass to just ≤102g within an IP67-rated enclosure. This ensures the module remains fully operational across -40°C to +60°C temperature variations. By integrating programmable range gating and a cumulative emission counter, it delivers a straightforward, reliable non-contact measurement solution for autonomous vehicles and infrastructure systems.
