91601-317

Rectangular Connectors - Headers, Receptacles, Female Sockets are extremely diverse in their designs and functions. An example of the most popular of this connector type is the 91601-317. This type of connector is mainly used in industrial and automotive applications, and this article will explain the purpose, working principle, and applications for the 91601-317 connector.

Purpose

The 91601-317 is a rectangular connectors header that is used primarily in industrial and automotive applications. It is designed for maximum current carrying capability, with a terminal pitch of 1.27mm and a centerline of 18.2mm. This connector can also withstand high vibrations, which makes it ideal for industrial and automotive applications.

Working Principle

The 91601-317 header works by having two rows of 10 connections that are connected to each other through a metal tab. The first row consists of 10 male contacts, while the second row consists of 10 female contacts. The two rows are connected to a metal housing that provides electrical insulation. The header operates on a simple principle: when a male contact is inserted into a female contact the connection is completed and current is directed through the contact pair.

The two contact rows can be used to accommodate small power signals and devices, such as LEDs and relays. The contacts are also designed to provide protection against short-circuiting. The header is also designed with a keying mechanism, which ensures that the correct contacts are chosen for the application at hand.

Applications

The 91601-317 header is mainly used in industrial and automotive applications. Due to its design, this type of connector is well-suited for applications where vibration or physical stress may be an issue. In industrial applications, this header is typically used to connect sensors, relays, and other such devices. In automotive applications, this type of connector is often found in high-fidelity audio systems, as well as engines and engine management systems.

The 91601-317 header is also suitable for applications requiring a high degree of protection from dust, moisture, and other environmental elements. Due to its metal housing, the connector is water-resistant and dust-repellent.

Conclusion

The 91601-317 is a popular type of rectangular connector header mainly used in industrial and automotive applications. It offers maximum current carrying capability, with a terminal pitch of 1.27mm and a centerline of 18.2mm, and is also designed to provide protection against short-circuiting. The header is also water-resistant and dust-repellent, making it an ideal choice for applications in tough environmental conditions.
