Product Descriptions from the Supplier

As an authorized partner of JONHON, MXTD is proud to present the YMA/YMB Series Marine Anti-Corrosion Waterproof Electrical Connectors— the ultimate interconnection solution for the most extreme marine and offshore operating conditions. Designed exclusively for marine scenarios, this dual-series product line is optimized for uncompromising reliability, with YMA’s bayonet lock for ultra-fast mating and YMB’s threaded lock for enhanced vibration resistance.

Crafted to exceed marine industry demands, the YMA/YMB Series delivers an impressive 50m waterproof rating after mating, far surpassing standard marine connectors. Its five-position orientation mechanism eliminates misplugging risks in complex shipboard systems, while the high-performance double-curved wire spring contact system ensures minimal contact resistance and consistent connectivity under strong marine vibrations and shocks. Available with stainless steel (passivated) or copper alloy (gold-plated)/aluminum alloy (chemical-plated) housings, the series offers exceptional corrosion, mold, and dust resistance—ideal for long-term use in saltwater and humid offshore environments.

Backed by MXTD’s professional technical support and global supply chain, we provide customized solutions for the YMA/YMB Series, including tailored contact configurations and installation adapters, to perfectly match the unique needs of your marine engineering, offshore oil, and shipbuilding projects. Every unit undergoes rigorous testing to ensure compliance with Q/21EJ814 and meets the strictest performance standards for marine applications.

Description

The YMA/YMB Series Marine Anti-Corrosion Waterproof Electrical Connectors are professional-grade interconnection components developed by JONHON specifically for marine and offshore harsh environments, divided into two sub-series to meet different connection speed and stability requirements. The YMA series adopts a bayonet quick-connect structure, enabling one-click fast mating/unmating for scenarios requiring efficient installation and maintenance; the YMB series features a threaded quick-connect design, providing a more secure lock for high-vibration marine equipment.

Engineered with marine-specific durability in mind, the connectors achieve 50m deep-water sealing after proper mating, effectively isolating seawater and moisture to protect internal electrical components. The five-position precise orientation design fundamentally prevents misplugging and wrong connection, avoiding equipment damage caused by incorrect wiring in complex marine systems. The core double-curved wire spring contact system uses gold-plated copper alloy contacts, ensuring ultra-low contact resistance, excellent conductivity, and resistance to fretting corrosion—even under long-term marine vibration and salt spray erosion.

The housings offer flexible material options: stainless steel with passivation treatment for maximum corrosion resistance, or copper alloy (gold-plated) / aluminum alloy (chemical plating) for lightweight and cost-effective solutions. The insulators are made of heat-resistant materials, and the sealing lines/ rings use high-quality silicone rubber, ensuring stable performance in the extreme temperature range of -55°C to +200°C. With multiple socket installation modes (flanged, perforated, pluggable) and a mechanical life of 10,000 mating cycles, the YMA/YMB Series is the first choice for reliable electrical connections in marine engineering, offshore oil platforms, shipborne systems, and underwater detection equipment.
