Rectangular Connectors - Headers, Male Pins

68021-134 Application Field and Working Principle

The 68021-134 is a rectangular connector in the category of headers, male pins. It is a part of the Standard rectangular header series produced by applications such as high-density surface-mounting applications. The Standard rectangular header series also includes items such as the 68020-126 and 68020-112. Capable of being terminated effectively, it provides an ideal solution for superior mating, miniaturization developments, and the demands of larger mating areas.

The 68021-134 is a three-pointed, 2 row, 3.96mm pitch (center to center) male connector. It is rated with a maximum current of 1.2A and a voltage of 125V AC. It is plated with a terminal finish composed of a tin, over nickel plating. This tin plating provides superior resistance to corrosion and the connectors may be soldered to a PCB with ease.

In terms of physical specifications, this male header has a width of 3.97 mm, a height of 1.27 mm and a length of 3.58 mm. The depth of the terminals is 0.5 mm and the number of pins is 30. It provides excellent contact, with a maximum contact resistance of 30mΩ. The 68021-134 is designed for reflow soldering methods as opposed to Wave soldering.

The 68021-134 is designed with a shrouded header housing. The shroud has two types of properties, contact properties and housing properties. Its contact properties include an excellent contact interface, resistance to corrosion and resistance to vibration. Its housing properties include a suitable pitch, a snap-in mounting and strain relief. The shrouded header also provides a secure u-lock by using a retention force of around 70N. This force prevents the connector from coming out during operation.

The working principle of the 68021-134 rectangular connector is quite simple. The two sets of contact pins are inserted into this connector. When the contact pins are mated, the connection is made, allowing for the transmission of current. The contact pin’s bodies are enclosed, providing a much more secure connection than if they were exposed. The contact pins are secured by the use of a retention force, providing protection from any bumps or jarring that may occur during operation.

The 68021-134 has a number of different uses, such as in telecommunication, broadcast, satellite, space, and instrumentation. Due to its superior mating, contact force, and protection from vibration and corrosion, this connector is also suitable for use in automotive, medical, and industrial products.

The 68021-134 is a great connector for applications where a secure, reliable connection is required. It is also ideal for applications that require resistance to vibration and corrosive elements, as well as superior mating. Thanks to its small footprint and variety of usable materials, it can be used in a variety of applications.
