Electric Strike ORNO OR-EZ-4027, symmetric mini with memory and lock, low-current 280 mA for 12 V DC

Electric Strike ORNO OR-EZ-4027 is a symmetric mini low-current lock release designed for 12 V DC systems. The device incorporates a memory function and a mechanical lock/block feature while drawing 280 mA in operation. Its compact dimensions make it suitable for installation in narrow door frames and retrofit applications where space is limited. The product is intended for access control systems, intercoms and other low-power installations requiring a reliable electric strike solution.

Advantages

The compact symmetric design allows fitting into narrow frames and both left- and right-hand doors without modification. Low-current operation at 280 mA for 12 V DC reduces power requirements compared with higher-consumption strikes. Integrated memory preserves the strike state for controlled release sequences, and the mechanical lock/block provides an additional physical locking option. The product's straightforward construction supports easy integration with intercoms and access control panels.

Suitable for

• Access control doors with limited frame space
• Apartment and office intercom systems
• Retrofit installations in narrow or older frames
• Low-power or battery-backed door release systems

Key specifications

• Operating voltage: 12 V DC
• Current consumption: 280 mA
• Symmetric mini design suitable for left- and right-hand doors
• Memory function to retain release state
• Mechanical lock/block mechanism
• Compact dimensions for narrow frame installation

How to use

Install the electric strike into the door frame in the prepared mortise, ensuring correct alignment with the latch or bolt. Connect the power supply and control wiring according to the access control or intercom system documentation, observing polarity for the 12 V DC input. Use the memory function and mechanical lock/block as required by the access control logic: the memory keeps the strike in its last commanded state while the mechanical lock/block can be engaged for manual securing. Verify operation by actuating the control circuit and confirming correct release and re-locking behavior.

Usage recommendations

For reliable operation, use a stable 12 V DC power source capable of supplying at least the rated current plus margin for wiring losses and system peripherals. Ensure the mounting surface and frame are structurally sound and that the strike is aligned with the door latch to avoid excessive wear. Regularly inspect mechanical parts for debris or wear, and perform electrical checks on wiring and supply voltage during routine maintenance.
