1. Flush Latch: The Stealth Guardian
Mechanics:
Spring-loaded mechanism creates flush surfaces (gap≤0.3mm) for IP67 sealing when engaged.
Advantages:
Space-saving (15–25mm thin) for compact cabinets;
316 SS + EPDM seals pass 96hr salt spray (ASTM B117);
Damped springs withstand 100Hz vibration (MIL-STD-810G).
Prime Applications:
5G base stations, medical devices, rail transit
Mingyi Innovations:
Magnetic-assisted alignment (40% less operating force);
Self-compensating hinge (Pat. CN2023XXXXXX).
