Rectangular Connectors - Headers, Male Pins

70246-2621 Application Field and Working Principle

The 70246-2621 rectangular connector is a popular choice amongst engineers and end-users alike for its versatile use in different applications. This connector is a surface mounted board-to-board connection with a half-pitch 2.54 mm system that is specifically designed for high-density applications. As part of the Molex family, it features a simple, efficient, and secure push-in terminal connection with polarized and keyed housings. It is commonly used in a variety of different settings, including automation, embedded systems, and instrumentation.The 70246-2621 rectangular connector features two distinct parts – a male header, and a female header. The male header is designed to fit into the female header, and creates an electrical connection between external elements. This particular model has a single row of 26 terminals on each side. The terminals are made out of tin-plated phosphor bronze and have a snap-in retaining feature to ensure the terminals and wires do not come out. These snap-in retainers also help maintain correct positioning of the terminals. The terminal side of the connector is coated in a thermoplastic material to protect it from short circuits and oxidation. The male pins are made out of brass, and have a 0.8mm profile to ensure that they fit securely into the female header.The working principle of the 70246-2621 rectangular connector is relatively simple. The male header is first inserted into the female header. This places the male pins into corresponding channels on the female header, which makes the connection secure. When the two halves are plugged together, the two sets of terminals make contact and an electrical connection is made. The internal contacts are designed to resist shock and vibration, which ensures a stable connection throughout its life cycle.The 70246-2621 rectangular connector is highly reliable and is made to withstand demanding environmental conditions. It is rated for up to 10A and 30VAC/1A and 40VDC, and its small size makes it suitable for use in tight spaces. This connector is also available in variety of colors to help differentiate between different systems and components.Overall, the 70246-2621 rectangular connector is an ideal choice for a variety of different applications. It is well suited for high-density designs due to its small size and robust terminals. Its optimized design for shock and vibration environments make it a reliable, long-lasting solution for any engineer.
