12V DC Fail-Secure Electromagnetic Lock – Reliable security, even during power outages
Need to manage access to an office, apartment block, or commercial space without the hassle of physical keys? This 12V DC electromagnetic lock is the perfect solution. It integrates seamlessly with your existing or planned intercoms, RFID readers, or access control panels.
Note: This lock operates in fail-secure mode — the door remains locked when there is no power and unlocks only when 12V DC is applied. Please verify compatibility with your system before purchase.
Why choose this electromagnetic lock? (Key Benefits):
- Native fail-secure operation — the door remains locked automatically during a power failure, providing enhanced security for sensitive areas.
- Quick installation — includes a mounting guide and a pre-attached 28 cm cable, making setup straightforward for both new installations and retrofits.
- Versatile door compatibility — works perfectly with metal, wood, and PVC doors without requiring structural modifications to the frame.
- Seamless system integration — easily connects to relay outputs on intercoms, RFID readers, and access control units that provide 12V DC.
- Compact design for tight spaces — measuring just 41.3 × 54 × 30 mm, it fits where other locks cannot, eliminating the need for complex milling.
- Heavy-duty construction — the robust housing is built to withstand repeated mechanical stress, making it suitable for both residential and high-traffic commercial use.

Frequently Asked Questions
What type of power does this electromagnetic lock require?
It operates exclusively on 12V DC. Please ensure your system’s power supply provides this exact voltage before installation.
What does ‘fail-secure’ mean in practice?
It means the lock remains automatically engaged when there is no power. The door only unlocks when the system sends a 12V DC signal. This is the recommended setup for offices, server rooms, or any area where an accidentally unlocked door would pose a security risk.
Will it work on my wooden or PVC door?
Yes. The included mounting guide allows for secure attachment to the frame regardless of whether the door is metal, wood, or PVC. No major structural changes are required.
Can I connect it directly to my existing intercom or RFID reader?
Yes, provided your system has a relay output that supplies 12V DC upon activation. This is the standard configuration for most intercoms and RFID readers on the market.
