Solenoid Locks for Intelligent Lock Systems
Intelligent lock systems are rapidly expanding in applications such as smart homes, access control, and shared economy (bike sharing, car sharing). Cixin Electromagnetic provides custom solenoid lock solutions for intelligent lock systems since 2011, with reliable performance and energy-efficient design.
Key Requirements for Intelligent Lock Solenoids
- Low power consumption: Battery-powered smart locks require solenoids with minimal power draw
- High reliability: Lock solenoids must operate reliably for years with minimal maintenance
- Compact size: Space inside lock housings is limited, requiring compact lock designs
- Secure locking: The lock must securely hold the door/lock in locked position until authorized opening
- Easy integration: Simple electrical interface for easy integration with lock control systems
Why Choose Bistable (Latching) Solenoids for Intelligent Locks?
For battery-powered intelligent locks, bistable solenoids (also called latching solenoids) are the ideal choice. They maintain their position without continuous power consumption, dramatically extending battery life.
| Feature | Bistable Solenoid | Standard Solenoid |
|---|---|---|
| Power Consumption (holding) | 0W (latching) | Continuous power required |
| Battery Life (typical smart lock) | 12-24 months | 1-3 months |
| Heat Generation | Minimal | Significant (continuous current) |
| Position Memory (power loss) | Yes (magnet holds position) | No (returns to default) |
Custom Solenoid Lock Solutions
At Cixin Electromagnetic, we offer full customization to meet your specific intelligent lock requirements:
- Voltage: 3V, 5V, 12V DC (custom available) – matched to your battery or power supply
- Stroke length: 5mm to 20mm (custom available) – sufficient to release the latch
- Force output: 0.5N to 30N (custom available) – sufficient to overcome latch spring force
- Current pulse: Optimized for your power budget (short pulse to switch state)
- Connector type: Wire leads, JST connectors, Molex connectors, or custom
- Mounting: Custom mounting bracket or flange for easy installation
- Environmental protection: IP54, IP65, or custom sealing for outdoor environments
Case Study: Smart Lock Manufacturer
Challenge: A smart lock manufacturer needed a lock solenoid that could operate for 12+ months on 4x AA batteries, while maintaining secure locking and reliable operation in outdoor environments.
Solution: We provided a custom bistable solenoid with 12V DC operation, 10mm stroke, 5N force, and IP65 environmental protection. The solenoid consumes power only during the 50ms pulse to switch states, allowing 12+ months of operation on 4x AA batteries.
Result: The customer’s smart lock system achieved 18-month battery life in field testing, with zero lock failures over 100,000 cycles. The custom mounting bracket reduced assembly time by 30%.
Applications
Smart Door Locks
Solenoid locks for smart door locks, enabling keyless entry via smartphone, RFID card, or biometric authentication. Bistable solenoids extend battery life to 12+ months.
Access Control Systems
Locks for access control systems in offices, apartments, and commercial buildings. Enable user-specific access via smartphone or RFID card.
Shared Economy (Bikes, Cars)
Locks for bike sharing, car sharing, and other shared economy applications. Enable 24/7 automated access with secure locking.
Hotel & Hospitality Locks
Specialized locks for hotel and hospitality applications. Operate reliably in high-traffic, 24/7 environments.

Integration Guide
Integrating our solenoid locks into your intelligent lock system is straightforward:
- Electrical interface: 2-wire connection (polarity matters for bistable solenoids – reversing polarity switches state)
- Driver circuit: H-bridge or relay driver to provide bidirectional current pulses
- Power supply: Battery (3V-12V) or external power supply
- Control signal: Simple pulse control (50-100ms pulse typically sufficient)
- Mounting: Custom mounting bracket or flange (we provide CAD files for integration)
