KEYENCE IL-300 Intelligent-L Laser Sensor

Keyence IL-300 CMOS Laser Displacement Sensor Head
 

1. Product Overview

IL-300 is a long-range laser distance measuring sensor head from KEYENCE IL series intelligent analog laser displacement sensors, paired exclusively with IL-series amplifiers (IL-1000 / IL-1500 / IL-1050 / IL-1550). It delivers stable high-precision non-contact distance detection over a wide 160–450 mm measurement window, designed for long-distance thickness, height, gap and position inspection in automation equipment, machinery, logistics and processing lines.
This unit adopts high-speed CMOS receiving chip and aspherical optical lens, supports diffuse reflection measurement for metal, plastic, wood and rubber workpieces. IP67 waterproof/dustproof housing adapts to harsh workshop environments with coolant mist, dust and splashing liquid. Abundant new original, surplus and fully calibrated refurbished units are available for OEM assembly and equipment maintenance replacement.
