Slim / Narrow Profile: Designed for mounting on narrow door frames (mullions) or tight wall panels where a standard-sized plate will not fit. Faceplates are typically stainless steel (often Grade 304) with a brushed finish for durability and a professional look .
Touchless Infrared (IR) Operation (Sensor Models): Many "slim" exit buttons are touchless, using an IR sensor to detect a hand wave from a short distance (typically 3–15 cm). This reduces the spread of germs and is ideal for high-traffic public buildings. Note that direct sunlight or reflections can affect sensor sensitivity .
Physical Push Button (Mechanical Models): Other slim models use a physical button (often 19mm or 25mm in diameter) that is nearly flush with the plate. These are designed for vandal resistance and reliable mechanical operation .
LED Status Indication: Most models include a dual-color LED to indicate status—typically Green for standby/active and Blue (or Red) for working/active mode, depending on the manufacturer's configuration .
High Durability Ratings: Quality units are tested for longevity, with mechanical life ratings ranging from 100,000 to 2,000,000 operations and infrared sensor life rated up to 100,000 hours .
Weatherproof Options: Some slim stainless steel models are rated IP65 for weatherproofing, making them suitable for both indoor and outdoor installations, while others are specified for indoor use only .
Contact Outputs: Standard models provide NO/NC/COM dry contact outputs for integration with access control panels and electric locks. Operating voltages are typically 12–24 VDC .
