Furuno CA50B-9B Rubber Coated Transducer, 1kW (No Plug)

The Furuno CA50B-9B Rubber Coated Transducer is a 1kW marine sonar transducer engineered for reliable underwater target detection and navigation in demanding saltwater environments. This 50 kHz transducer delivers consistent performance across a 12×28 degree beam angle, making it the choice for maritime professionals who depend on proven sonar technology for search and rescue operations, hydrographic surveying, and offshore vessel operations.

The CA50B-9B features a protective rubber coating that guards against corrosion and impact damage during deck-mounted installation on patrol boats, research vessels, and tactical watercraft. Rated for 1 kilowatt transmission power, this transducer penetrates through water column clutter while minimizing power draw—a critical consideration for extended operations where electrical reserve matters. The 15-meter cable provides installation flexibility for hull, chest, or tank mounting configurations. The unit ships without a connector, allowing installers to configure termination to match existing Furuno FCV series ecosystems. An optional 75 kHz frequency setting is available on compatible FCV1100/1200 and FCV1200BB systems, expanding operational adaptability.

This transducer serves maritime operators—Coast Guard personnel, naval technicians, commercial fishermen, and hydrographic teams—who operate in salt-air and saltwater environments where equipment failure is not an option. The rubber coating directly addresses the corrosion and galvanic degradation that threaten unprotected transducers in these conditions. At 11.3 pounds and measuring 14 × 5 × 15 inches, the CA50B-9B integrates into compact sonar installations without creating topside weight penalties or structural complications.

Furuno transducers have maintained market presence in professional maritime sonar systems for decades, known for consistent signal clarity and long service intervals in harsh salt-water duty. The CA50B-9B continues that lineage as a replacement or upgrade component for established Furuno fishfinder and navigation sonar suites, ensuring compatibility with proven electronics already installed on working vessels.
