George Risk Industries 4613 2 in. Gap Curtain Door Contact

Detect the open or closed position of an aluminum curtain door in a security circuit with a magnetic switch set built around a 2 in. gap. The SPDT output provides a changeover contact for alarm inputs that require either normally open or normally closed signaling. An armored cable carries the switch lead from the protected door area toward the fixed wiring path. George Risk Industries 4613 fits curtain-door applications where the moving door and fixed mounting surface need a contact arrangement that tolerates separation up to its stated 2 in. gap. Aluminum construction suits installations requiring a metal-bodied contact assembly. The switch-set format provides the sensing components used to create a door-position circuit rather than supplying a general electrical cable alone. What distinguishes this configuration is its combination of a 2 in. operating gap, armored cable lead, aluminum construction, and SPDT switching. These details matter where the contact must follow a moving curtain door while maintaining a defined alarm-circuit state. Connect the SPDT contact to the appropriate monitored input arrangement and route the armored lead to protect it from movement, abrasion, and accessible cable damage.
