The YB-31NO/NC is a surface-mountable, medium-sized plastic door contact. It features a reed relay with NO/NC contacts (3 screw terminals), meaning it detects both normally open and normally closed states. This allows for detecting if the door is closed, disconnected, or short-circuited. It is ideal for access control systems to provide feedback on door status.
