Slot-type photoelectric switch is also called U-type photoelectric switch, which is a photoelectric product that works through infrared induction. Its slot width determines the strength and distance of the receiving model. It uses light as a medium to detect the position of an object through infrared light. Slot-type photoelectric switches are widely used. Slot-shaped photoelectric switches are used in elevators, conveyor belts, packaging machinery, stamping machinery, unmanned vehicles, automatic assembly machinery, etc. There are three main considerations for the selection, 1. slot width, 2. light slit width, and 3. fixing method.
 

      1. The width of the groove, the detection object needs to pass through the groove of the groove-type photocoupler to block the infrared light, so the groove width of the photoelectric sensor should be wider than the detection object, and there must be a certain margin for easy installation. (Slot-shaped photocoupler ITR8402 slot width 6.0mm)

      2. The width of the light slit of the slot-type photoelectric switch (photoelectric switch), if the test object is a toothed disk, the width of the toothed disk is d, the width of the toothed disk slot is f, and the slot-type photoelectric switch is a slotted optocoupler The width of the optical slit should be less than d and less than f, so as to ensure that the infrared light can be effectively blocked and conducted. Under the above conditions, choose a slot-type optocoupler with a wide optical slit.

　　3. Groove-type optocoupler (photoelectric switch) shape: with fixing holes and fixing posts, please choose according to the actual situation.

　　4. Installation position: When the photoelectric sensor is installed, the outer diameter of the detection gear should be 1-2mm beyond the optical axis of the grooved photocoupler. This can effectively block the light.

Slot-type photocouplers, U-type photocouplers, slot-type photoelectric switches, U-type photoelectric switches, slot-type photoelectric interrupters, U-type photoelectric interrupters are widely used in: card readers, game machines, ATM machines, currency detectors, and currency counters Machines, printers, paper inspection devices, copiers, fax machines, scanners, barcode readers, automatic vending machines, automatic ticket vending machines, and other optoelectronic products
