Left Connector: * High pin count (likely over 30 pins). * Suitable for high-density signal applications. * Square flange with mounting holes for panel attachment. Right Connector: Lower pin count (approx. 4–6 pins). * Possibly for power or low-signal lines. * Also flange-mounted with bayonet coupling slots. Olive drab cadmium plating**: Corrosion-resistant and EMI shielding. Bayonet coupling: Ensures secure and vibration-resistant mating. Polarization key-ways: Prevent misalignment during connection. Panel gaskets: Likely included for environmental sealing (IP-rated).
