The ML100 sensor combines all advanced photoelectric functional principles in a simple, rectangular miniature housing design to solve all kinds of demanding automation tasks. It features M3 metal threaded mounting holes, a bright emitter LED and a highly visible LED status indicator. A sensitivity adjuster and a light-on/dark-on changeover switch allow greater flexibility and increased control of the sensing or detection range. The sensor housing is cULus listed and CE, UKCA, and CCC certified. Due to its ruggedness, the ML100 series can easily withstand cold-storage applications with temperatures down to −30 °C. All optical versions come cabled or with M8 connectors, as well as with NPN and PNP outputs. This helps users meet the requirements of any installation.

Technologies: PowerBeam vs. BlueBeam

ML100 series with BlueBeam technology

PowerBeam Technology

The PowerBeam technology is known to have the highest operating reserve among competitors, ensuring the most stable and reliable operation. The highly visible emitter LED allows for easy alignment and convenient setup of the sensor. Its large, bright and uniform light spot is especially useful for retroreflective sensors, even for those with small reflectors.

BlueBeam Technology

The BlueBeam technology is similar to the PowerBeam technology, but features a blue LED with a wavelength of 470 nm. It has an equally powerful and uniform light spot. This can be used to solve some of the most difficult tasks in the electronics industry, including the detection of blue solar wafers and printed circuit boards (PCBs).
