Product Description
1. A trough photoelectric sensor is a trough photoelectric sensor in which a light emitter and a receiver are installed face to face on both sides of a trough. The emitter can emit infrared light or visible light, and the light receiver can receive the light if there is no obstruction. But when the object to be detected passes through the slot, the light is blocked, and the photoelectric switch operates, outputs a switch control signal, cuts off or turns on the load current, thereby completing a control action. The detection distance of the slot switch is generally only a few centimeters due to the limitation of the overall structure;
2. Slot type sensor, the shape is similar to U-shaped, and the transmitter and receiver are installed in the same U-shaped housing;
3. No calibration and alignment is required during installation, and wiring is convenient;
4. Miniature slot sensor: slot width 1.8-5mm, no built-in amplifier;
5. Standard slot sensor: slot width 10-220mm, red light and infrared light optional;
Product Features
Economical and practical, suitable for various purposes
Available in multiple series specifications such as K type, L type, T type, R type, Y type, etc.
All models are equipped with two independent outputs: 0N when light enters and ON when light is blocked.
The display light is clear and easy to confirm the action.
Large range voltage output type with power supply voltage DC5-24V

How to Use
Cautions
The resolution of the groove type optical coupler. If the detection object is a toothed disc, the width of the toothed tooth of the toothed disc is d, and the width of the toothed tooth slot of the toothed disc is 3, then the width of the optical slit of the grooved optical coupler must be less than d and less than f. , so as to ensure that infrared light can be effectively blocked and conducted. When the above conditions are met, choose a groove-type optocoupler with a wide light slit. Pay attention to the selection of slot width. The detection object needs to pass through the slot. The slot width of the electric sensor should be wider than the detection object, and there should be a certain margin for easy installation. Installation location. When the sensor is installed, the outer diameter of the detection gear plate should exceed the optical axis of the grooved optical coupler by 1-2mm. This can effectively block light. Trough-type optocouplers are available with or without fixing holes, which can be selected according to the actual situation.
