Engineering Overview & Sizing
A Half Euro Profile Cylinder features an active keyway on one side only, with a solid unbroached rear face. Standard modular dimensions measure 10/30 mm or 10/35 mm, where the nominal 10 mm segment houses the central drive cam.
Primary Commercial Applications
- Fire Exit & Panic Doors: Installed on emergency egress doors where exterior entry is barred while interior panic hardware remains operational.
- Electrical & Server Enclosures: High-voltage substations, elevator panels, and telecom cabinets requiring standard DIN 18252 master keying.
- Roller Shutters: Key-switch housings for motorized warehouse doors.
8-Position Adjustable Cam
Quality half cylinders feature an internal spring-loaded pin allowing the cam to be indexed in 45° increments (8 positions), ensuring positive alignment with diverse electrical microswitches or mechanical linkages.
