The Bioteknix NO TOUCH-SQ-7-K2 is a touchless exit switch designed to enable hygienic, contact-free door release in access control systems. It uses an infrared motion sensor that detects the presence of a hand or object within an adjustable sensing range (typically 1–15 cm). When motion is detected, the device sends an electrical signal to unlock the door or release an electromagnetic lock without requiring physical contact. This reduces the risk of germ transmission and enhances user convenience in high-traffic or sensitive environments such as hospitals, laboratories, offices, and clean rooms. The switch features a durable stainless steel square panel (86 × 86 mm) for corrosion resistance and longevity. Operating on 12V DC power, it integrates easily with most access control systems, providing a reliable and safe hands-free exit solution.
