Rectangular connectors are one of the common types of connectors used in electronics and related applications. They have a variety of features and applications, and the 3440-5303 is one of the most popular connector types available. This article will provide a detailed overview of the 3440-5303 application field and working principle.

The 3440-5303 is an electrical connector with two rows of 4mm contact pins, designed to provide a secure match-up with two mating connectors. It is typically used in general industry applications such as power plants, transformer rooms, medical equipment, robotics, instrumentation and process control. It is also commonly used in the automotive industry for battery connections, fuel systems, wiring harness connectors, etc.

The 3440-5303 uses a two-piece snap-together design, meaning that it is easily mated and secured to any mate-able connector such as a 4mm mating piece. It uses a unique latching mechanism which allows the device to be easily inserted and securely held in place. The contacts are also designed to provide good electrical contact with a mate-able connector when they come into contact during mating.

The 3440-5303 is constructed from a single piece of die-cast metal. This makes it strong and robust, with a good level of corrosion resistance. It is also insulated, ensuring that it will not cause any electrical shorts or other disruptive effects in related electronics.

The 3440-5303 has two distinct electrical contact designs, a standard and an alternate-gap. The standard contact design features parallel contact pins which are captured in a single piece of insulation material. The alternate-gap design features an alternating-gap in which the pins are not captured in the insulation, but free to move and independently contact any compatible mate-able connector.

The 3440-5303 has a relatively high current rating, typically up to 10A reaching 16A in a single bundle. It also offers a variety of additional features such as color coding and LED status indication. This makes it suitable for a wide range of applications.

The 3440-5303 is designed to meet strict safety standards. It has a high insulation voltage, and its insulation material has a UL certification. It also has an IP67 dust and water resistance rating, and is rated at +125°C.

In summary, the 3440-5303 is a rectangular head connector, with two rows of 4mm contact pins, designed for general industry and automotive purposes. It is constructed from a single piece of die-cast metal, with high insulation voltage, IP67 rating and UL certification. It has a relatively high current rating, and offers a variety of additional features such as color coding and LED status indication. This makes it a suitable and reliable choice for a wide range of applications.
