Q: For the navigation system of civil cargo ships with weak signals, which connector should be selected to reduce attenuation?

A: Select M12 B-code connectors (4Pin) with gold-plated contacts (thickness ≥5μm), contact resistance <3mΩ, and signal attenuation ≤0.1dB/100 meters. They can ensure stable reception of GPS navigation signals (L1 frequency band 1575.42MHz) and adapt to the ocean navigation needs of cargo ships.
