Nano-SIM Card Socket Connectors

1. Basic Definition


The Nano-SIM card (12.3mm × 8.8mm × 0.67mm) is the smallest SIM standard. The socket connector is used to secure and transmit signals in compact devices like smartphones and IoT products, requiring miniaturization, high reliability, and anti-interference capabilities.

2. Core Structure & Features


- Mechanical Design:  
  - Housing: Made of heat-resistant plastic (e.g., LCP) for lightweight insulation.  
  - Metal Contacts: 6-8 gold-plated copper alloy pins for power, data, and signal transmission.  
  - Spring Mechanism: Side springs or pogo pins ensure stable contact after card insertion.  
  - Dust Protection: Some models include sliding/flip covers to prevent dust ingress.  
- Electrical Performance:  
  - Contact resistance ≤50mΩ, insulation resistance ≥100MΩ, withstand voltage 500V AC.  
  - Supports 2G/5G frequency bands; impedance optimization for high-frequency signals.  

3. Types & Selection Criteria


- Mounting Methods:  
  - SMT (Surface Mount): Space-saving, ideal for consumer electronics (e.g., smartphones).  
  - DIP (Through-Hole): High mechanical strength, used in industrial equipment.  
- Actuation Mechanisms:  
  - Push-Push: Press-to-eject design, cost-effective (e.g., Moarcoon NS125-T1250 ).  
  - Flip-Type: Dust-resistant with intuitive operation (e.g.,Moarcoon NS143-T1151 ).  
  - Tray-Based: Requires a tray for hot-swapping (e.g.,Moarcoon NSKT-Z0000-13 ).  
- Key Selection Factors:  
  - Size: Height typically 0.8-1.2mm; ultra-thin versions for wearables.  
  - Durability: 1,000-5,000 cycles (consumer-grade); ≥10,000 cycles (industrial).  
  - Environment: Operating temperature -40°C to +85°C (automotive: up to 105°C); IP54+ for dust/water resistance.  

4. Typical Applications


- Smartphones/Tablets: Ultra-thin SMT sockets.
- IoT Devices: Low-power, vibration-resistant designs.  
- Automotive Electronics: High-temperature/impact-resistant, AEC-Q200 compliant.  
- Wearables: Miniaturized sockets (<1.0mm height).  

5. Common Issues & Trends


- Troubleshooting: Contact failures often caused by oxidation/dirt—clean regularly; avoid non-standard SIM cards.  
- Future Trends:  
  - eSIM Integration: Compatibility with embedded SIM chips.  
  - Miniaturization: Adaptation for AR glasses and smaller devices.  
  - High-Speed Transmission: Optimized 5G mmWave support.
