The 91910-21151 is a rectangular connector that falls under the category of Arrays, Edge Type, Mezzanine (board to board) connectors. With so many types and sizes of electronic connectors available, it is useful to classify them by their application and mode of operation. This article will cover the 91910-21151\'s application field and working principle.

The 91910-21151 is suitable for a wide variety of applications, such as semiconductor testing, data communications networks, medical diagnostics equipment, avionics, and industrial machinery. It is a 4 row, 2.54mm (.100") pitch, non-surface-mount, rectangluar connector. It is a shrouded header that provides insulation and protection against EMI/RFI. The connector comes with a polarization feature to ensure proper mating.

The 91910-21151 features high-temperature thermoplastic insulation and contacts made from copper alloy and gold-plated. It offers low contact resistance and high durability, enabling reliable contact over the long term in various types of equipment. The connector is also versatile, as it is available in jumper headers, strip headers, and board-plug receptacle housings.

The working principle of the 91910-21151 is to conduct electrical current between two points by means of a contact. The contact, or pin, is embedded in an insulation material, such as thermoplastic. When the connector is inserted into its mating part, the pins come into contact with its corresponding contact on the mating part, creating an electrical connection between the two parts. The insulation on the pins and housing help to minimize the risk of short-circuit or leakage.

The 91910-21151 is designed for top-entry mounting, and features a 9mm depth for reliable securement. The connector is also RoHS compliant, which assures safety from hazardous substances and environmental pollutants. Its high-reliability design makes it a popular choice for a wide variety of electronics applications.

In conclusion, the 91910-21151 is a 4 row, 2.54mm (.100") pitch, non-surface-mount rectangualr connector designed for a variety of applications. It features high-temperature thermoplastic insulation and copper alloy contacts with gold-plating, as well as a polarization feature for proper mating. The working principle of the connector is to conduct electrical current between two points with contact pins embedded in an insulation material. Its securement and RoHS compliance make it a reliable and safe choice for the electronics industry.
