The FS-N series by Keyence is a series of digital fibre optic sensor amplifiers. This series bring an entirely new concept in setup ease. All it takes is one click to calibrate the sensitivity and resets the display. The automatic maintenance function detects light intensity reduction due to dirt or misalignment. "High power" = "large excess gain" that not only reduces the need for maintenance but also expands sensor head capabilities. We are here to help you find the right sensor for your application, so do not hesitate to contact us with your questions.
