Introduction

DF1E-12P-2.5DS(05) is a two-position rectangular connector which belongs to the Headers, Male Pins category of rectangular connectors. Engineered to satisfy specific demands for power and/or signal connections, these connectors are ideal for use in a wide range of applications such as automotive electronics, industrial, scientific and medical (ISM) applications, and consumer electronics. This article will provide an overview of the application field and working principle of the DF1E-12P-2.5DS(05) connector.

Application Field

The DF1E-12P-2.5DS(05) connector is a two-position, nondetachable rectangular connector which is ideally suited for providing signal and power connections in a variety of applications. These connectors are typically used in telecommunications, automotive electronics, consumer electronics, aerospace and defense, instrumentation, and industrial applications. For example, they are extensively used in medical equipment, automotive, control systems, broadcast, wiring harness, and instrumentation. In addition, these connectors are compatible with SCSI, Ethernet, and USB connectors.

Working Principle

The DF1E-12P-2.5DS(05) connector is designed to operate under the power and signal transmission principles of a two-conductor system. The system consists of an inner pair and an outer pair of contacts which are paired together. The inner pair works as the power contacts, and the outer pair are the signal contacts. The inner contacts are designed to carry higher currents and are capable of withstanding larger contact pressures. The outer contacts are suitable for significantly smaller currents and carry the signal.At the contact, the DF1E-12P-2.5DS(05) connector is equipped with two electrical pathways, one for the power leg and the other for the signal leg. The electrical pathway for the power leg includes an insulator which separates the two contacts. This is done to prevent any cross or short-circuiting that may occur between the two contacts. The electrical pathway for the signal leg is a single-armor insulated construction which limits the transmission of interference between the two contacts.

Conclusion

The DF1E-12P-2.5DS(05) connector is a two-position rectangular connector which is designed for providing power and signal connections. It is commonly used in a number of applications in the automotive, consumer electronics, aerospace, and instrumentation industries. The connector is engineered to work under the principles of a two-conductor system and is able to provide reliable power and signal transmission without interference.
