The unit uses proximity sensing to detect a hand gesture, triggering the door operator without physical contact. This makes it well suited for installations where hygiene, accessibility compliance, or high-traffic flow is a priority. The CM-221M\/42 is installed by licensed electricians or door system technicians as part of a complete automatic door or access control assembly.\u003c\/p\u003e\n\u003cp\u003eThe CM-221M\/42 is used in commercial and institutional settings including healthcare facilities, food service environments, offices, and public buildings where touchless entry is required.
