399-40-126-10-009000

Rectangular Connectors - Headers, Male Pins, known as 399-40-126-10-009000, are widely used components in electrical systems owing to their defining feature: it does not require soldering to attach it and can be detached and reattached easily. This type of connector comes with a printed circuit board and is specifically designed for circuit board assemblies in computers, cars, and home electronics. It also serves as an adapter for different connectors with distinct shapes.

The 399-40-126-10-009000 connector features a right angle header type, and consists of two rows of 40 single pins. The spacing between the two rows is 2.54mm (one 0.100"), and the spacing between the pins is 0.1”. It is copper-plated, and the top case is made of a thermoplastic material for insulation and to protect components. The package itself is SMT-type, ensuring that it is easy to mount on circuit boards.

This connector is designed to work in an environment with a temperature ranging from -20℃ to 85℃. The contact is 1.5A/contact while the contact resistance is less than 50mΩ. While the insulation resistance can stand up to 500V, the maximum voltage threshold is 250V. Its current capacity is also within a safe range, limited to 1.5A/contact.

It also operates with a mating cycle of 5000. Manufacturing wise, this type of connector is rated to be UL 94V-0 compliant, and is compliant with RoHS standards.

The working principle of this type of connector is simple. In the mating process, each single pin makes contact with one complementary pin, and the contact is assured by an elastic pressure. This also allows for an effective tension as well as a low tweezing force.

In order to ensure safety and security, each contact in the 399-40-126-10-009000 connector is designed with an additional bent pin with an extra length to ensure the firmed and complete contact.

The connector is widely used in many different industry, owing to its reliable performance in connecting two systems or circuits together with minimal interference. It is commonly used in medical equipment, 3D printers, and cars. Its ability to work in higher temperatures also makes it a great choice for heat-generating devices such as motors and automotive parts.

Overall, the 399-40-126-10-009000 connector is featured with excellent performance and reliability, making it a great choice for applications that requires secure connection between two systems or circuits.
