Rectangular connectors are a broad class of components used in a wide variety of applications including computers, telecommunications, industrial, consumer electronics and more. They are typically either edge connectors, pin connectors or mezzanine connectors. The 91931-21169 is a two-row, right-angle header array connector with a common pitch of 2.54mm.

Edge connectors are used to connect two printed circuit boards or other devices together in an electrical signal path. The 91931-21169 features gold contacts with receptacles and is rated for up to 10A. It has both through-hole or surface mount configurations and is RoHS compliant. The physical properties of the 91931-21169 are as follows: Pitch – 2.54mm, Number of Contacts – 20, Contact Resistance – 10 mΩ, Current Rating – 10A, Duty Cycle – 1.4 cycles/minute for 180˚ rotation, Operating Temperature – -55˚C to +105˚C, and Total Height – 8.3 mm.

Mezzanine connectors are typically used to make connections between two printed circuit boards. Unlike edge connectors that connect PCBs in a vertical arrangement, mezzanine connectors allow for a variety of stackable and grid-style arrangements. The 91931-21169 is a suitable mezzanine connector with a shallow total height of 8.3 mm, making installation easy. The 91931-21169 mezzanine connector is designed to be as durable as it is reliable. With its gold contacts, it offers superior electrical conductivity and corrosion resistance, while still providing the reliability and flexibility of a right-angle, two-row header array connector. Additionally, its two-row configuration allows for higher flexibility in terms of signal routing and space utilization.

The 91931-21169 can be used in a variety of applications due to its wide operating temperature range and 10 A current rating. It can be used in telecommunications, industrial, automotive, medical, and aerospace applications. The 91931-21169 is suitable for use in both digital and analog circuits, in both prototype and production environments.

The working principle of the 91931-21169 is simple and straightforward. The connector is designed to bridge a signal path between two or more PCBs through electrical contact between pins in one row and their corresponding contacts in the other. The contacts are arranged to locate and retain the connector during the normal assembly process, allowing even force to be applied for high electrical reliability.

The 91931-21169 is a versatile connector that is suitable for a wide range of applications. Its two-row, right-angle, header arrangement makes it ideal for use in shallow spaces, while its gold contacts provide superior electrical conductivity and corrosion resistance. Additionally, its low profile and secure latch mechanism make it easy to install and reliable in operation. Its wide operating temperature range, current rating, and corrosion resistance make the 91931-21169 the perfect choice for a variety of applications.
