Rectangular Connectors - Headers, Receptacles, Female Sockets generally come in various shapes, sizes and characteristics. Their primary purpose is to mate multiple circuit elements, such as wires, cables, or other components, to provide the desired electrical and mechanical connection between two or more elements. The DF3-4S-2DSA (55) connector is a field-installed and rated female connector with a soldered-in, polarized, four-lug terminator design and four receptacle pins. It provides a reliable connection for use in harsh environments and is commonly used in the military, medical, and aerospace industries.

The connector features a polarized design, which allows for a correct orientation of the connector when it is mated with another mating part. The silver-plated brass shells are designed to reduce electrical and radio frequency interference to provide a higher level of reliability. The shell and tubes are gold-plated to maintain electrical continuity and to provide a low-impedance path to ground. The connections are made using an integrated four-pin design that maintains improved contact alignment for a secure fit.

The DF3-4S-2DSA (55) connector is constructed with a pocket cable release which allows for easy installation and removal of the connector, minimizing the risk of damage to the electrical circuits. The connector is rated to withstand up to 550VAC, 400VDC with a temperature range of -45 to +90 degrees Celsius. The connector is also certified for use with medical devices, as it meets the UL requirements and is RoHS compliant.

In terms of its working principle, the DF3-4S-2DSA (55) connector provides an effective electrical connection by allowing the current from each pin on the connector to flow without any interference to the next pin in the contact assembly. It also provides a secure mechanical connection between two or more circuit elements, such as wires or cables, which can be reused multiple times. It is important to ensure that the connectors are firmly attached before applying power to the circuit, as any loose connection could result in a malfunction of the connected device.

Overall, the DF3-4S-2DSA (55) rectangular connector is a reliable and durable connector which is suitable for a variety of applications in harsh environments. It is designed to provide a secure connection to ensure the uninterrupted and reliable flow of power between two elements. Its high temperature rating and RoHS compliance make it an ideal choice for applications in the medical, military, and aerospace industries.
