Description
The Fotek CDM-2MX retro-reflective photoelectric sensor, supplied with the dedicated MR-1 optical reflector, delivers high-accuracy presence detection tailored for industrial automation, conveyor sorting, and high-speed packaging machinery. Built on an M18 standard cylindrical footprint with robust IP66 ingress sealing, the sensor utilizes specialized optical polarization filtration to eliminate false triggers caused by specular reflection from high-gloss, metallic, or shrink-wrapped targets.

INDUSTRIAL APPLICATION & SOLVED ISSUES
Standard diffuse sensors often experience false switching when detecting reflective packaging materials, polished aluminum tooling, or wet surfaces. The Fotek CDM-2MX paired with the MR-1 reflector solves this issue by rotating polarized light waves, ensuring the internal receiver only triggers when light is returned via the specialized corner-cube prism array. This makes it ideal for automated bottling lines, clear container tracking, logistics palletizing, and metal stamping stations.
