DF3-4S-2DSA(25) Connectors, Interconnects

The DF3-4S-2DSA(25) connector belongs to the group of rectangular connectors - headers, receptacles, and female sockets. It is a multipurpose connector designed for wire to board and board to board applications. It is often used in consumer electronics and appliances.

The connector features high reliability, designed for surface mounting and utilizes friction locks. It has simple, secure press-fit installation, which requires no soldering, and can easily be replaced. It is suitable for a wide range of applications, and can be used in humid environments, as it has superior moisture resistance.

The connector is designed with a dual orientation, which makes it possible to mount two cables of the same size in different orientations. The terminal is designated in 2 positions, which makes it easy to connect two wires of the same size. It has a low contact resistance of 5MΩ which improves signal transmission. It also conforms to the IEC 6051 requirements for safe insulation.

The DF3-4S-2DSA(25) rectangular connectors are composed of a plastic receptacle and male header. The receptacle is made of UL 94V-0 rated thermoplastic and is designed to be flexible enough to account for misalignment. The header is made of high-temperature nylon and has 2 sets of 4 contacts. The contacts offer excellent electrical contact performance, with a current rating of 4A and voltage rating of 250V.

The contacts fit securely into the terminal housing, ensuring that no loosening of the contacts occurs during cable movement. It has a high temperature range, with an operating temperature of -55°C to +125°C. It is RoHS compliant, and the assembly process is fast and easy.

In terms of working principle, the DF3-4S-2DSA(25) connector is designed to be easy to assemble. It is designed with a push-in installation method, whereby the contacts can be connected without the need for soldering. The contacts fit securely into the terminal housing, ensuring that no loosening of the contacts occurs during cable movement. It has a high temperature range, with an operating temperature of -55°C to +125°C and high polarizing forces that is designed to prevent the contact from loosening during use.

When used in combination with a mating connector, the DF3-4S-2DSA(25) connector can provide a tight mechanical and electrical connection between two wires or devices. As a result, this connector is an ideal choice for a wide variety of applications, including consumer electronics, automotive, communication, industrial, and medical applications.
