The 5278 touchless proximity switch utilizes optical infrared technology, and the embedded sensors pick up motion within a 4-in. range. A simple wave of the hand activates the switch; no hand contact is required. The 5278 greatly decreases the potential to spread contagious diseases since no actual hand contact is required to activate. These switches are often utilized with electronic locks and automatic door operators. The 5278’s illuminated LED ring allows for visibility under low-light conditions.
