Rectangular Connectors - Arrays, Edge Type, Mezzanine (Board to Board) are part of the big family of electrical connectors. The 91900-31511 series is an Italian naval submerged type that’s been in use for many years. It’s used to ensure reliable electrical connections between two or more systems, often in a submerged environment. The 91900-31511 is often used in applications such as fuel systems, electrical and hydraulic systems, and others in which a reliable connection is more important than ensuring long-term integrity.

Long-Term Connector Durability

The 91900-31511 Connector has been specially designed for increased durability, so it can withstand harsh marine environments. The part is made from a corrosion-resistant material and is hermetically sealed with an additional polyethylene coating for added protection. This ensures reliability and extended lifetime use. The components of the connector are constructed of reinforced plastic and incorporate double locked screws, which give the part a high degree of sealed tightness.

Key Features

The 91900-31511 Connector has a number of distinct features that make it suitable for submerged applications. The part has a molded construction with an impact-resistant polyurethane which resists abrasion and offers superior resistance to oil and other chemical agents. The part also features a latch for easy installation and secure locking and a shielded protection system to prevent accidental disconnections.

Operation and Connections

The 91900-31511 Connector series consists of two types of connectors, the SUB-M and the SUB-B. The SUB-M is the traditional type of connector for submerged applications, while the SUB-B is an alternative for submerged applications as well as dry-environment installations. Both types of connectors typically have two sets of pins, one for each system being connected. The pins are connected via the arced contact board, which has a protective cover. Once the pins are connected, each system connection is completed by screwing in the connectors.

Safety and Reliability

One of the primary advantages of the 91900-31511 Connector is its ability to provide reliable and safe connections. The connectors are equipped with two integrated seals that prevent water and dust from entering the system. This ensures that the connection is secure and free from moisture, dust, and other contaminants, ensuring maximum efficiency and reliability.

The 91900-31511 Connector Series is made to be highly reliable and durable, allowing them to be used in a wide range of applications. They are suitable for use in submerged applications as well as dry environments. Their robust construction and reliable sealed connections ensure safety and long-term reliability.
