The Force Behind Modern Access Control
When it comes to electromagnetic locks, not all designs are created equal. Since 1983, SDC’s EMLocks® have defined what the industry expects from a magnetic locking solution—reliability, simplicity, and uncompromising performance. In fact, the term “EMLock” is often used synonymously with premium electromagnetic locks across the industry. This isn’t just branding—it’s earned authority.
1. Proven, Failsafe Security
Electromagnetic locks are inherently failsafe, meaning doors unlock during power loss—critical for life safety and fire compliance. SDC EMLocks® deliver instantaneous release without mechanical delay, ensuring safe egress in emergencies.
Unlike mechanical locks, there are no moving parts to bind or wear out, making them exceptionally reliable over time.
2. Patented Design That Changed the Industry
SDC revolutionized electromagnetic locking with its interlocking EZ mount assembly—a breakthrough that simplified installation and reduced labor time. Key innovations include:
This modularity allows EMLocks® to be stocked, installed, and serviced with unmatched efficiency.
