The Yokogawa KN-004G is a marine-grade gyrocompass repeater connection box manufactured by Yokogawa Denshi Kiki Co., Ltd. (Yokogawa) in Japan. Designed as a dedicated signal distribution and cable junction box, the KN-004G interfaces Yokogawa master gyrocompass systems (such as the CMZ-500, CMZ-700, and CMZ-900 series) with various bridge heading repeaters, including bearing repeaters, steering repeaters, and digital heading indicators.

Housed in a rugged metal enclosure, the KN-004G contains internal terminal barrier strips that allow clean, reliable splitting and termination of heading data lines (such as step signals, synchro feeds, or NMEA 0183 serial outputs). Equipped with heavy-duty cable glands, it protects heading transmission lines from electrical noise, moisture, and mechanical strain on commercial vessel bridges.

Key Features:
• Multi-Channel Heading Distribution: Reliably routes and branches master gyro compass signals to multiple remote bearing, steering, and wing repeaters.
• Yokogawa CMZ System Compatibility: Purpose-built for seamless integration with Yokogawa CMZ series master compasses and distribution units.
• Signal Isolation & Noise Protection: Internal barrier terminals provide clean connection paths that minimize signal attenuation and electromagnetic noise.
• Rugged Wall/Bulkhead Mount Housing: High-durability metal enclosure constructed to withstand shipboard vibration, humidity, and temperature shifts.
• Secure Cable Strain Relief: Fitted with multiple watertight cable entry glands to ensure secure, splash-resistant cable termination.
