MCBHRA5F 5-Pin Female Right-Angle Bulkhead Underwater Connector – Miniature Circular L-Type Series
Product Overview
The
HYSF SUBSEA MCBHRA5F 5-Pin Female Right-Angle Bulkhead Underwater Connector is a compact subsea electrical connector designed for underwater equipment requiring reliable five-channel connectivity and space-efficient installation.Belonging to the HYSF Miniature Circular Right-Angle Connector Series, the MCBHRA5F features five female electrical contacts and an integrated 90-degree right-angle configuration.Unlike conventional straight bulkhead connectors, its right-angle design directs the internal cable leads sideways from the connector mounting interface. This helps reduce axial installation clearance and simplifies cable routing inside compact underwater housings.The five-pin configuration provides a practical electrical interface for power, signal, control, and instrumentation applications.With a compact Ø15.7 mm body, the MCBHRA5F is designed for installations where available space is limited and multiple underwater electrical connections need to be integrated into a small equipment housing.The connector features IP68 waterproof protection and pressure capability up to
60 MPa (approximately 6,000 meters of seawater depth).The standard bulkhead cable configuration is approximately 0.3 meter, with customized lead lengths and mounting configurations available according to project requirements.The MCBHRA5F is particularly suitable for ROVs, AUVs, underwater cameras, marine sensors, sonar systems, subsea monitoring equipment, and compact underwater electronic modules.
Key Features and Benefits
1. Five-Pin Female Electrical Configuration
The MCBHRA5F features five female electrical contact positions arranged in a compact miniature circular connector interface.Its five-pin configuration provides multiple electrical channels through a single bulkhead connection.Typical applications include:
