What are the three types of latches

- Jul 21, 2025-

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).
