Molex Straight Edge Connector 4-Contacts 12.9mm Pitch Through Hole, 2 Row, Solder, 250V, 40A 45719-0004

The Molex 45719-0004 Straight Edge Connector is a high-performance, through hole Edge Connector designed to provide robust connectivity in demanding electronic and industrial environments. This connector utilizes a 12.9 mm pitch with a 2 row, 4-contact configuration, making it particularly suited for applications requiring a secure dual-edge interface with reliable current carrying capabilities.

Engineered to handle a rated current of up to 40 A and voltage of 250 V, the Molex 45719-0004 is suitable for rigorous power and signal requirements. Its gold over nickel plating on copper alloy contacts ensures outstanding conductivity and long-term corrosion resistance, critical for applications where reliability is non-negotiable. The connector's through hole mounting and solder tail termination deliver a strong mechanical retention on PCBs and enable straightforward, permanent assembly during production.

This connector is designed to mate with 1.58 mm (0.062 inch) double-sided card edge or bus bar tabs, providing broad compatibility with existing board designs. The dual edge contact system features isolated segments on opposing contacts, rated for current interruption and true hot-swapping, which enhances safety and flexibility during equipment servicing or upgrades. The housing, made from liquid crystal polymer, is engineered for both mechanical stability and high-temperature durability, allowing the device to operate reliably from -40°C up to 105°C.

Typical applications of the Molex 45719-0004 connector include use in power distribution assemblies, server and data processing equipment, industrial automation modules, and as card-to-board connectors in control systems. Its stackable end-to-end design and straight orientation support versatile configurations within both compact and large-scale electronic assemblies.

Whether employed within manufacturing facilities, laboratory instruments, or advanced telecommunications infrastructure, the Molex 45719-0004 provides engineers and designers a practical solution that combines high electrical rating, mechanical stability, and proven material performance. Its robust construction, reliable solder tail connection, and compatibility with a range of card edge PCB types make it a trusted choice for demanding environments.
