Device	Series	Advantage
GPS (Portable or vehicle-mounted）	K,E	Socket waterproof, anti-shock and vibration, a perfect shield.
High-pressure experiments	M（high-voltage Or mixed）， B（mixed）	Comprehensive protection measures (locking ring, positioning tag, the internal switch), a simple plug, solid and reliable.
Instrumentation， Power，	B, M, EX-PLS,	Swapping reliable, different colours and pin inserted to avoid misuse. At the same time can be mixed-core and high-power transmission, low-frequency signals.
Meteorological sensors	K,E	Seal protection can be used for outdoor. Mixed-core configuration (low / high-pressure, coaxial, optical fiber), to reduce the number of connectors.
Quality Control	B, M	Multi-Core and mixed (low / high-pressure, coaxial, optical fiber) needle-core configuration, space-saving connections to reduce the number of connectors
