Description
Fork sensors have a collimated laser beam with a very small diameter of 0.35 mm over the entire fork width. As a result, they’re capable of detecting extremely small parts down to a size of just 40 µm and even transparent objects at high speeds of up to 10 kHz. The innovative layout of the fork sensors in hygienic design permits various fork widths within a range of 50 to 220 mm, and allows contamination and cleaning agents to flow off of the surface in an ideal manner.
