ELXT05500E

Terminal blocks are crucial electrical components used in countless electrical connections and assemblies. The ELXT05500E terminal block is a multipurpose electrical connector manufactured by Molex, Inc. This part is a high-density board-to-board or board-to-wire interconnect component designed specifically for the aerospace and industrial bus marketplaces. It is a multi-functional terminal block that provides high power and signal integrity, as well as multiple termination options.

The ELXT05500E terminal block is a 5.50 mm (0.217”) pitch terminal block that provides pin-out flexibility. With this connector, up to 32 discrete conductors can be packed densely into 0.0035” space, enabling the user to maximize the space available within a given application. The ELXT05500E is available with starter pin headers or with integrated retainer clips.

The ELXT05500E terminal block provides many features and benefits to users. It is designed to minimize stray capacitance between contacts, providing more efficient signal transmission. The integrated retainer clips also provide a secure hold on both low and high power and signal circuits. This ensures a secure connection even during the most extreme conditions. Additionally, the terminal block offers vibration resistance and is designed to meet UL standards. The insulation structure enabled by the retainer clip also prevents thermal expansion and contraction by completely enclosing the terminal.

The rated current and voltage of the ELXT05500E terminal block depend on the configuration and application. It is typically rated for 5A, however higher ratings are available. The max voltage is also largely dependent on the application. Standard available models are rated for 300V. Higher voltage models, up to 1000V, can be custom ordered.

The ELXT05500E terminal block is primarily suited for aerospace and industrial bus marketplaces. In the aerospace environment, the terminal block could be used to connect remote sensors, actuators, and switches to the main bus. In industrial environments, the ELXT05500E is typically used to connect large control panels to the main buses. The terminal block can also be used to connect multiple PCBs to one another. This could be used in industrial control systems, as well as medical and communication applications.

In terms of working principle, the ELXT05500E is a wire-to-board or board-to-board connector. The terminals are made of brass or copper and typically feature gold plating. The retainer clip is made of thermoplastic, and the insulation is typically made out of polypropylene. The connection is established when the mating pin is inserted into the terminal. The retainer clip then secures the connection, ensuring that the terminal block won’t come loose or vibrate out of position.

The ELXT05500E may seem like a simple electrical component, but in reality it is an incredibly versatile connection solution. Its small form factor, high power and signal integrity, and integrated retainer clips make it a great choice for high-density applications in the aerospace and industrial bus marketplaces.
