The Omron EE-SY169B is a panel-mounted limit switch with a silver-chrome-plated, die-cast housing and a contact rating of 12A and 250VAC. It features a momentary two-circuit switch, with one normally closed and one normally open circuit, and a built-in lever for greater switching accuracy and long life. The contact blocks and head type are easily swappable, and the contact block supports non-contact sensing. It also includes an audible click sound for easy recognition and a high IP66 rating for protection against dust and water ingress.
