Balluff’s new wafer mapping sensor, BOH00EZ, uses a precise photoelectric sensor for quick and reliable detection of semiconductor wafers and slotting errors in FOUPS – front opening unified pods.
Especially designed for use with extremely thin end effectors, it features a controlled and focused light spot, allowing it to detect wafers even just a few μm thick with extreme precision.
Based on photoelectric Micromote technology, it features the smallest LED sensor on the market in a small sensor head – measuring just 2.4 x 1.5 x 7 mm. This allows it to deliver precision in even the smallest spaces.
In addition to wafer mapping, this sensor delivers capabilities that can be used for a variety of applications that require through beam sensors in a small area, such as life science and food and beverage applications.
