Pepperl + Fuchs: Divergent beam photoelectric sensors detect transparent, small, glossy targets without a reflector

With the ability to independently detect clear shrink wrap film, PET plastic bottles, glass and other transparent objects without a background, Pepperl+Fuchs’ ML100-8-W divergent beam sensors eliminate the time, cost and machine space associated with installing reflectors.

ML100-8-W sensors can also reliably detect small objects such as wires, yarns or pins over a large area.  This facilitates reliable parts detection with a forgiving set-up, and without the need to precisely align a laser or small light spot fiber optic head to the object. Effective sensing solution for glossy materials such as foil pouches or shiny PCBs.  ML100 series sensors feature multi-color LEDs that are visible from 360° over long distances for immediate sensor status detection.  They are also highly resistant to ambient light, and feature cross-talk protection.  Unique PowerBeam alignment with an intense light spot and an industry-standard mounting pattern reduce set-up time, and fully metal bushings provide extremely durable operation even in extended temperature environments from 30° C to +60° C (-22° F to +140° F).  These UL and cUL listed sensors are said to reduce energy costs by up to 43% compared with competitive models. 

Divergent sensing, also known as wide beam sensing, covers a larger surface area of the target to optimize the likelihood that some part of the object is perpendicular to the light beam and minimize the occurrence of sensing voids.
