Overview
The Amphenol 62GB 37-pin circular connector is a miniature bayonet-lock connector designed and manufactured to MIL-DTL-26482 Series E specifications. This 62GB series offers keyway orientation to reduce mis-mating among multiple connectors. The plug features a robust aluminum shell, gold-plated contacts, and solder bucket terminations, making it suitable for demanding military, aerospace, communications, and industrial applications where secure, vibration-resistant connections are critical.
Key Features
