KJRF-A4 High-Frequency Laser Ranging Sensor
✨Features
Product Introduction
This High-Speed Dynamic Laser Distance Sensor is designed for automation applications requiring rapid response and versatility. With a lightning-fast 0.5ms response time, it excels in dynamic environments, reliably tracking objects moving at speeds exceeding 2 meters per second.
The sensor's advanced optical system overcomes common detection limitations, allowing it to measure black targets (such as coal and rubber), semi-transparent materials, and even black mirror-like surfaces that confuse traditional lasers. It offers a measurement range of up to 10m (on high-reflectivity targets) and remains operational in outdoor environments with ambient light up to 100,000 Lux.
Housed in a compact, lightweight shell (80g), it provides unmatched integration flexibility with built-in RS485, 4-20mA, NPN, and PNP interfaces. Standard IP65 protection ensures durability, with an IP68 option available for submersible or washdown applications.
