Features

Transparent object detection: The retroreflective configuration supports detection of transparent targets using a sensing head and reflector positioned across the sensing path.
Built-in high-power lens: The integrated lens provides a high-powered beam for stable detection, including environments affected by dust and particles.
Up to 2,025 mm detection: The maximum detecting distance reaches 2,025 mm, with actual range depending on the fiber amplifier, operating mode, and sensing conditions.
Easy M6 nut mounting: The M6 nut-type head can be held with a wrench and secured with a single nut for straightforward installation.
R2 free-cutting fiber: The 2 m free-cutting fiber supports an R2 allowable bending radius, while the side-exit design helps reduce protrusion and cable snagging.
