The 3440-5603 is a very versatile rectangular connector belonging to the Headers, Male Pins type. It is specifically designed for use in high-density applications and provides a quick, secure connection between two devices and is capable of enduring high-voltage and high-current applications. The 3440-5603 is a standard Black Zinc-plated interconnect that is also environmentally sealed for extra protection from the elements.The main features of the 3440-5603, within the context of rectangular connectors, include:- High current and voltage handling capabilities: rated up to 2 Amps, 600 Volts- Durable NiSold Gold plated terminals to ensure a secure, efficient connection- Environmental seal: the connectors are sealed for maximum protection against shock, vibration, corrosion and environmental extremes- Quick and easy to install for cost-effective application- Mates with standard rectangular and square connectors- High temperature rating allows for use in applications up to 125 degrees CelsiusThe 3440-5603 is a relatively simple device and thus its working principle is straightforward. The device is composed of a few basic components and components: a housing, contacts, a crimping system, and a sealing mechanism. The housing has four sides with a series of slots cut into the sides which allows the contacts (usually made of NiSold Gold) to be inserted into the housing. The crimping system is used to secure the contacts to the housing. It is achieved by squeezing the crimping lug onto the contact using a specially designed tool. This ensures an electrical connection between the contact and the housing and a physical connection due to the crimping forces. The contact is housed in the connector body, and the sealing is achieved by a rubber or plastic seal that sits between the contact and the connector body. This seal prevents dust, dirt, and moisture from entering the connector.The 3440-5603 is typically used in a wide variety of electrical and electronic products due to its reliable performance and secure fit. It is suited for high-current, high-voltage applications and is most commonly used for power distribution in automotive and industrial control systems, medical equipment, fire protection systems, and telecom systems.In conclusion, the 3440-5603 rectangular connector is an ideal choice for high current and voltage applications. It is a quick and secure connection device, with high current and voltage ratings and durable NiSold Gold plated contacts that provide an efficient electrical connection. Its environmental seal also makes it a great option for external applications in harsh environments. The 3440-5603 is a reliable, cost-effective solution for many electrical and electronic devices.
