An infrared Request to Exit (REX) switch is a component commonly used in access control systems to provide a hands-free and contactless method for allowing egress from a secured area. The infrared REX switch utilizes infrared technology to detect motion or the presence of a person within its detection range. When an individual approaches the exit, the infrared sensor triggers the release of the door lock, allowing the person to exit without the need to physically touch a button or handle.

This technology is particularly useful in situations where maintaining a hygienic environment is important, such as in healthcare facilities, clean room environments, or during times of heightened concern for the spread of germs. Additionally, it provides convenience and accessibility for individuals with disabilities or those carrying items that make it difficult to manually operate a traditional exit button or lever.

Infrared REX switches are designed to integrate seamlessly with access control systems, enhancing security while also ensuring a smooth and efficient flow of authorized personnel in and out of protected areas.
