Cornell 4560-016 Rollerball Door Contact

Description:

For locations where visual appearance is important. Once installed, these devices are concealed within the door frame, and are hardly visible unless the corresponding door is opened. Rollerball Contacts require a relatively large hole to be bored into the Door Frame for installation. They are customarily installed on the Hinge Side of the Door Frame, such that when the door is closed, the integral “roller plunger” is depressed into the housing by the edge of the door. The Contact Housing and associated Field Wiring are hidden within the Door Frame / Mounting Hole. This type of Contact is somewhat less secure than Magnetic Types – because the door must usually be opened to a considerable arc / swing before the internal switch will be actuated.
