Electromagnetic Lock Factory
Whether you're designing the next generation of shared mobility solutions, upgrading vending machine security, or building intelligent storage systems, the locking mechanism is the heartbeat of your product. That's where the KR-S822 Series Mini Electromagnetic Lock from KERONG comes in—a compact, reliable, and versatile solution trusted by engineers and manufacturers worldwide.
Small in Size, Big on Performance
Don't let its miniature footprint fool you. Measuring just 54 × 23.7 × 29.7 mm, the KR-S822 series is engineered for space-constrained applications where every millimeter counts. But beneath its sleek, well-designed exterior lies a robust solenoid-driven mechanism capable of delivering 2000N of holding force with a 10mm stroke—more than enough to secure cabinets, lockers, equipment panels, and automated systems with confidence.
The lock's carbon steel nickel alloy electroplating construction ensures long-term durability, while its proven rotary latch design provides vandal-resistant security that stands up to real-world abuse.
Built to Last, Certified for Trust
Reliability isn't just a feature—it's a promise. The KR-S822 series has been rigorously tested to exceed industry standards:
Working Life: 200,000+ cycles, dramatically reducing after-sales service and replacement costs
Salt Spray Resistance: Passed 96+ hours of salt spray testing, ensuring excellent corrosion resistance even in harsh environments
Operating Temperature: -20°C to +60°C, making it suitable for both indoor and outdoor applications
Certifications: CE, RoHS, and FCC compliant, meeting global regulatory requirements for safety and environmental standards
Energy-Efficient & Cost-Effective
One of the standout features of the KR-S822 series is its instantaneous power consumption design. Unlike locks that require continuous power to maintain a locked state, this electromagnetic lock uses power only during the brief moment of actuation. Operating on 12V or 24V DC with a power consumption of just 19.2W, it helps reduce energy costs and extends the life of your power systems—an increasingly important consideration in battery-powered and solar-powered applications.
Flexible Integration for Any Project
Engineers love options, and KERONG delivers. The KR-S822 series supports:
Multiple lock hook directions: Left, Right, Up, and Down configurations to accommodate various door and panel orientations
2-6 wire input options with the ability to handle multiple input signals
Customizable wires and connectors to seamlessly integrate with your existing control systems
Whether you're building a smart locker network, an automated production line, or a next-gen shared bicycle station, the KR-S822 series adapts to your design—not the other way around.
