Connectador passamurs de born - Passadors 3/8"-16 (Negre)

A bulkhead connector is a device designed to allow the safe passage of electrical cables through a bulkhead, hull, or deck while maintaining circuit integrity and protecting the cable. It is used to connect equipment on either side of a wall, ensuring a reliable and watertight connection.

The primary function of the BLUE SEA 2203-BSS through-bulkhead connector is to secure the passage of high-current cables through hulls, decks, or bulkheads. It prevents cable abrasion and provides strain relief for large-section cables, ensuring reliable and protected electrical distribution.

The BLUE SEA 2203-BSS through-bulkhead connector body is made of black reinforced thermoplastic. Specifically, this material is ZYTEL PA66 FR50NC010, which provides insulation for the bulkhead stud and offers good resistance.

The connection studs of the BLUE SEA 2203-BSS bulkhead connector are made of tinned copper alloy. The tin plating ensures high conductivity and excellent corrosion resistance, which is particularly important in a marine environment.

This specific model, the BLUE SEA 2203-BSS, is black in color. It is identified as the black version of the small through-bolt connector.

The BLUE SEA 2203-BSS through-bolt connector is rated for a maximum continuous current of 250 amperes (DC).

This bulkhead connector is suitable for systems operating at a maximum continuous DC voltage of 48 volts.

The BLUE SEA 2203-BSS bulkhead connector has an IP66 rating.

The IP66 rating means the connector is fully protected against dust ingress (first digit 6) and protected against powerful water jets from any direction (second digit 6). This makes it suitable for harsh marine environments and water spray exposure.

Yes, the connector’s studs are made from tinned copper alloy, providing excellent corrosion resistance essential for reliable use in a marine environment.

For optimal installation, a Ø 24 mm or Ø 7/8" (approx. 22.2 mm) hole is recommended for mounting this connector.

The connector is designed to be mounted using #10 or M5 screws.

The recommended torque for the studs of the connector is 11.3 Nm (Newton-metres) or 100 in-lb (inch-pounds) to ensure secure connections.

The mounting face of the connector is designed to be gasketed or coated with a suitable sealant to ensure a perfectly watertight installation through the bulkhead.

Available information does not indicate that mounting screws are included with the connector. It is generally necessary to source #10 or M5 screws separately.

The connector body is approximately 33.3 mm (1.31 inches) thick. The studs have a total length of about 79.4 mm (3.13 inches). This means there is approximately 23 mm of threading available on each side after passing through the body. The connector can pass through a bulkhead thick enough to secure the nuts and terminals on each side.

This connector is ideal for installations requiring the passage of high-current power cables, particularly for equipment such as windlasses, electric winches, or other energy-intensive marine devices.

The connection studs of this connector have a 3/8"-16 UNC thread. This means a nominal diameter of 3/8 inch with 16 threads per inch, unified coarse thread type (UNC).

The 3/8"-16 studs are designed to fit large-section cable terminals, typically used for high currents. Compatibility depends on the terminals used, which must match a 3/8 inch hole for the stud and be sized for the cable gauge.

This specific product is model 2203 (black). There is also a red variant, identified by part number 2204, although this product is the 2203-BSS black.
