Through-bulkhead connector - 5/16"-18 studs (Red)

The BLUE SEA 2202-BSS watertight bulkhead connector is designed to allow safe passage of high-current cables through bulkheads, firewalls, hulls, and decks. It provides a robust solution to protect cables from abrasion and ensure strain relief, preventing premature wear and short-circuit risks.

This connector is fitted with 5/16"-18 UNC (Unified National Coarse) studs at two locations, designed for reliable connections.

The BLUE SEA 2202-BSS connector is rated for a maximum current of 250 amperes (A).

The maximum operating voltage for this connector is 48 volts DC.

Yes, this connector is designed to be waterproof. Its design includes a mounting face for a gasket or seal to ensure a watertight installation, meeting IP66 standards. This standard provides protection against dust and powerful water jets, including those in rough seas.

The connector's base material is reinforced thermoplastic (Zytel PA66 FR50NC010), which insulates the stud from the bulkhead. The studs are made of tinned copper alloy, providing superior corrosion resistance and high conductivity.

The connector ensures a reliable connection thanks to the use of serrated flange nuts. These nuts provide robust and secure connections, essential for managing power electrical circuits on board.

This specific BLUE SEA bulkhead connector model is red in color.

Unlike simple grommets, the 2202-BSS connector provides a robust and secure connection for high-current cables. It includes connection studs and serrated flange nuts for reliable terminations, while also offering abrasion protection and strain relief, which a standard grommet does not.

Yes, the connector’s base material is reinforced thermoplastic, which insulates the stud from the bulkhead it is mounted on.

Tin-plated copper alloy studs provide superior corrosion resistance, which is critical in marine environments, and high electrical conductivity for optimal performance.

This connector is ideally suited for applications requiring reliable power distribution management onboard vessels, particularly for high-power electrical circuits where connection robustness and safety are critical.

Installation involves drilling holes for mounting studs and screws in the bulkhead, firewall, or deck. The mounting face of the connector is designed to allow the application of a sealant or caulking to ensure IP66 waterproofing compliance. Cables are then connected to the studs using serrated flange nuts.

The connector requires clearance for #10 or M5 screws for mounting. The technical drawing specifies a clearance of 0.21 inches (5.2 mm) for these screws.

To ensure watertightness, the mounting surface of the connector is designed to be used with a suitable gasket or sealant during installation. This achieves compliance with IP66, protecting against dust and powerful water jets.

The connector is designed to be mounted on bulkheads, firewalls, hulls, and decks, allowing safe cable routing through these surfaces in a marine environment.

Yes, the dimensional drawing shows a spacing between the centers of the mounting holes. The horizontal spacing is 2.00 inches (50.8 mm) and the vertical spacing is 1.31 inches (33.3 mm) between the centers of the mounting holes.

This connector is compatible with cables whose terminals match the 5/16"-18 stud size. It is specifically designed for high-current cables requiring a robust and secure connection.

Yes, this connector is specifically designed for marine environments. Its corrosion-resistant materials (tinned copper studs, reinforced thermoplastic base) and compliance with IP66 standard make it ideal for nautical applications, including those exposed to spray and powerful water jets.

The BLUE SEA 2202-BSS connector is rated for a maximum voltage of 48V DC (direct current). It is not recommended for alternating current (AC) applications unless the AC voltage and current specifications are clearly defined and below the DC ratings, which is not the case here.
