Frequently Asked Questions (FAQs)
1. What is a Photomicrosensor?
A Photomicrosensor is a small photoelectronic sensor with an amplifier built into it that is used primarily as a component for building into equipment. Like any ordinary photoelectric sensor with a built-in amplifier, it is used, for example, in applications to detect passing objects or in positioning applications.
2. How does a slot sensor work?
Working principle of slot photoelectric sensor The illuminator can emit infrared light or visible light, and the light receiver can receive light without obstruction. But when the detected object passes through the slot, the light is blocked, and the photoelectric sensor starts to work.
