Rectangular Connectors - Headers, Male Pins are one of the most common types of electrical connector used to connect wires to printed circuit boards. The 3440-6203 header is a type of two-row, straight inline connector developed and manufactured by Samtec, Inc. and is part of their Tiger Eye™ product family. In this brief, we will discuss the application field and working principle of the 3440-6203.

This specific series of headers come in a variety of pin counts, ranging from 6 to 80 positions. Each pin is a specific length and is outfitted with a locking latch that allows for secure connection and loading. The total thickness of the connector is 0.8mm. The connector is designed and manufactured with gold flash plating over soldered tail pins that reduces cost and improves wear characteristics. The connector is designed to carry 2.0 amps of current and features an operating temperature range of -55°C to +125°C.

One of the primary use cases for the 3440-6203 header is in the automotive industry. Due to its small form factor and reliable locking, it is commonly used on automotive connector components, such as dashboards, door locks, and power windows. The 3440-6203 is also commonly found in other industries, such as consumer electronics, medical, and industrial.

The 3440-6203 operates using the principle of dual beam connections. The top and bottom rows of the header feature two rows of soldered tail pins which make direct contact with the printed circuit board. The center row features two rows of spring steel contacts which are inserted into the center pin of the header. When the center pin is inserted into the printed circuit board, the spring steel contacts make contact with the board and establish an electrical connection.

The 3440-6203 is designed with a simple but efficient locking mechanism in order to ensure proper connection and loading. The part features steel locking tabs that cling to the printed circuit board when the part is inserted. The tabs then pull the connector firmly onto the board and ensure that it is locked in place.

The 3440-6203 is an efficient and reliable two-row, straight inline connector that is made with a gold flash over soldered tail pins and features a steel locking latch. Its small form factor and reliable locking make it an ideal choice for a variety of applications, such as automotive, consumer electronics, medical, and industrial. The connector operates by using the principle of dual beam contacts, with two rows of soldered tail pins making direct contact with the board and two rows of spring steel contacts providing an electrical connection.
