| Product Introduction
The WCPX300 series slot-type photoelectric sensor, also known as a slot-type photoelectric switch, U-shaped photoelectric sensor or opposed-type photoelectric switch, is a photoelectric detection device that integrates an infrared or visible light emitter and receiver face to face on both sides of a U-shaped slot. When a target object passes through the slot opening, it blocks or changes the light beam, and the receiver outputs a switching control signal based on the change in light intensity.
The WCPX300 series slot-type photoelectric sensor uses a non-contact detection method with no mechanical wear, featuring fast response, high repeat positioning accuracy, strong anti-interference and easy installation. Different slot widths, output modes, housing materials, cable or terminal interfaces can be selected according to application needs, with NPN/PNP and normally open/normally closed output forms supported. It is widely used in automation equipment such as SMT, printing, LED equipment, electric gates, loading/unloading, vibration bowls, modules for limit, counting, positioning, speed measurement and edge detection.
| Features
1. High-accuracy positioning: U-shaped opposed structure with a short optical path, suitable for small object, edge and position detection.
2. Fast response: suitable for high-speed counting, speed measurement, pulse signal output and similar applications.
3. Non-contact detection: no mechanical contact, no wear, long service life.
4. Strong anti-interference: modulated infrared light design, minimally affected by ambient light and electromagnetic interference.
5. Flexible output modes: NPN/PNP output selectable;
6. Multiple slot widths available: meets the needs of objects of different sizes and installation spaces.
7. Compact structure: integrated U-shaped housing, convenient installation and commissioning.
