The reflective photoelectric switch (USW1IR_A) is a customizable USB button that functions as a standard HID USB keyboard and mouse. The switch can be programmed to act as any key, key combination, mouse function, or string using the provided software. Once configured, no additional software is required during operation.This device is commonly used in printers, copiers, game consoles, factory testing, instrumentation, and industrial equipment. It is also suitable for mobile monitoring, proximity detection, and applications where mechanical switches are impractical, helping to improve efficiency.The switch operates using a reflective photoelectric sensing method. An infrared emitter on the panel sends out invisible infrared light. When an object approaches, the light reflects back to the sensor, triggering the switch. The activation distance can be adjusted via the configuration software, with an effective range of approximately 030 mm.For optimal performance, use with materials that have good reflective properties, such as white paper. Avoid use in environments with strong ambient light, such as outdoor areas or balconies, to prevent false triggering.Product name: Reflective Photoelectric Switch Rated voltage: 5 V Operating frequency: 3600 times/hour Applications: Office, gaming, industrial, accessibility Color: Black Material: ABS Size: 2 m Package Contents: 1 x HID Reflective Photoelectric Switch Note: The package includes only the items listed above.
