E3S-GS15 slot-type photoelectric switch sensor for position detection
Working Principle
The U-shaped photoelectric switch has a 'U' shaped structure, with an infrared LED (emitter) and a phototransistor or photodiode (receiver) installed on both sides. The infrared beam emitted by the emitter passes through the U-shaped slot to the receiver. When an object enters the U-shaped slot and blocks the light beam, the light intensity received by the receiver changes, causing a change in the internal circuit state and outputting the corresponding switch signal.
Product Features
1. U-shaped through-beam structure, no alignment required, easy to install, strong anti-interference
2. 15mm standard slot width, highly versatile, suitable for most automation scenarios
3. High-speed response (≤1ms), suitable for high-speed counting and positioning
4. Wide voltage (12–24V DC), compatible with mainstream industrial control systems
5. IP65 protection, dustproof and waterproof, suitable for industrial environments
6. Red/green indicator lights, intuitively display working and stable status
7. Adjustable sensitivity at the back, adaptable to different materials and thicknesses
8. No mechanical contacts, long lifespan, maintenance-free
application scenarios
1. Automated Production Line: Part counting, in-place detection, origin positioning
2. Packaging / Printing: Paper / label counting, color mark detection, correction
3. Logistics / Sorting: Material in place, belt speed measurement, material shortage alarm
4. 3C / Electronics: PCB inspection, component positioning, terminal in place
5. Textile / Rubber & Plastic: Roll counting, material break detection, tension control
6. Elevator / Door Control: Leveling, door in place, safety edge
