Slotted Optical Switch

Slotted optical switch, also known as U-shaped photoelectric switch, concave photoelectric switch, travel limit switch, etc., is a type of opposed photoelectric switch. It is an infrared induction photoelectric sensor composed of an infrared emitting tube, an infrared receiving tube, and a circuit board chip. It uses light as the medium and receives and converts infrared light between the emitting body and the receiving body to detect the position of objects. The concave groove type photoelectric switch is commonly used for module limit positioning, shaft rotation reading (reading rotation and speed), detecting the discharge of paper or textile fabrics to be brushed, bearing limit stroke, and so on. It is widely used.

1. The depth of the induction slot is 5mm.
2. Provide two output circuits, NPN/PNP normally open and normally closed.
3. A bright indicator used for output confirmation, visible from multiple directions.
4. All models are equipped with standard cables
5. Provide load short-circuit protection and offer 2-meter pre-wiring option.

1. Slot width: To detect an object, it is necessary to pass through the slot of the slot photoelectric sensor, which cannot be too large to block infrared light. Therefore, the slot width of the U-shaped photoelectric switch should be wider than the detected object and have a certain margin for easy installation.
2. The appearance of groove-type photoelectric devices: with fixed holes, multiple options for external dimensions and installation methods. Please choose according to the actual situation.
3. Installation position: When installing the slot type photoelectric device, the outer diameter of the detection gear should exceed the detection point by 1-2mm. This can effectively block the light.
4. Response speed: If there is a high-speed application, attention should be paid to whether the switching frequency of the slot-type photoelectric meets the usage requirements. Slot type photoelectric can reach an ultra-high speed of 2KHz.
5. Environmental factors: If applied in environments with strong light, bright sunlight, and natural light, attention should be paid to selecting sensors that are resistant to strong light interference. Garantta slotted optical switches have been tested to resist strong light interference of over 20000 Lux.
6. Diversity of groove shapes: U-shaped, F-shaped, R-shaped, K-shaped, L-shaped
