3.5 mm Key B Sealed Plug 33482-6202: Technical Overview The 3.5 mm Key B Sealed Plug (Part No. 33482-6202) is a precision-engineered electrical connector designed for reliable performance in demanding environments. This plug features a 3.5 mm diameter interface with a Key B configuration, ensuring proper polarization and secure mating with compatible receptacles. Its sealed construction provides protection against moisture, dust, and contaminants, making it suitable for industrial, automotive, or outdoor applications where environmental resistance is critical. Key Features 1. Keyed Design (Key B): The plug incorporates a Key B alignment feature, which prevents incorrect insertion by ensuring it only mates with corresponding Key B receptacles. This design minimizes connection errors and enhances safety in complex wiring systems. 2. Sealed Construction: Built with IP-rated sealing (exact rating depends on application), the plug resists water, dirt, and debris. This makes it ideal for harsh conditions, such as automotive wiring, marine electronics, or industrial machinery. 3. Durable Materials: The housing is typically made of high-temperature-resistant thermoplastic or metal, ensuring mechanical strength and longevity. The contacts are often gold-plated or tin-plated for optimal conductivity and corrosion resistance. 4. 3.5 mm Interface: The compact 3.5 mm diameter suits space-constrained installations while maintaining robust electrical performance. It supports low-voltage signals, commonly used in sensors, audio devices, or control systems. 5. Secure Locking Mechanism: Many variants include a threaded coupling, snap-in latch, or bayonet lock to prevent accidental disconnection due to vibrations or movement. Applications - Automotive: Sensor connections, infotainment systems. - Industrial: Factory automation, robotic controls. - Consumer Electronics: Audio equipment, portable devices. - Outdoor/Defense: Ruggedized communication gear. Installation Notes - Ensure proper alignment of Key B before insertion. - Verify sealing integrity (e.g., O-rings, gaskets) for waterproof applications. - Follow torque specifications if using threaded locking. Conclusion The 3.5 mm Key B Sealed Plug 33482-6202 combines precision, durability, and environmental protection, making it a versatile solution for secure electrical connections in challenging conditions. Its keyed design and sealing technology ensure reliability across industries. (Note: Specifications may vary based on manufacturer; always refer to datasheets for exact details.)
