91920-21125

Rectangular Connectors - Arrays, Edge Type, Mezzanine (Board to Board)

The 91920-21125 connector is a modular board-to-board connector made up of an array of 10 connectors designed for daisy-chaining circuits. It is configured with 0.070" spacing, which offers the highest density of any standard rectangular connector. It is designed with both vertical and horizontal standoffs, allowing for higher spacing flexibility.

Application Field

The 91920-21125 application field has a wide range, from high-speed data transmission to signal control terminals and relay connections. This style connector makes it perfect for applying to communication and control systems suitable for computer motherboards, PCI slots, connectors, terminal blocks and many other micro-electronic devices. The compact design of the connector makes it ideal for applications where space is limited or where multiple pieces of equipment must be interconnected.

Working Principle

The 91920-21125 connector operates on the principle of two-directional flow control. When the two connectors are directly plugged into each other, the array is completed, enabling a two-way flow of data and power from the host device to all the connected devices. The connectors can also be daisy-chained, allowing multiple connections from a single host device to multiple connected devices. This style of connector is designed with a lever available on each connector, which is used to quickly disconnect and reconnect a connector from the array.

The connector\'s rigid construction ensures a secure fit, helping to reduce the risk of accidental disconnection or damage to the connector. The use of positive and negative terminals in complicated systems and the two-way flow of data and power make the 91920-21125 especially reliable in the field.

Advantages and Limitations

The 91920-21125 connector offers a number of advantages over other connector types. Its inline array design allows for extremely high density connections, and its small size means that it can fit into space-constrained applications. It is designed to withstand vibrations and environmental conditions, making it especially suitable for mobile and mission-critical applications.

One limitation of the 91920-21125 connector is that it can only be used in a direct line and daisy-chained situations. In cases where a connection is required in a perpendicular direction, another type of connector must be used. Additionally, the design of the connector means that it is more sensitive to handling than some of its counterparts.

Conclusion

The 91920-21125 connector is an indispensable component in applications where high density interconnection is required. Its array design allows for a high number of connections even in tight spaces, and its leakage-free design makes it a reliable option even in high-vibration and mission-critical applications. While being limited to two- direction flow and direct and daisy-chained connections, the 91920-21125 package offers an unbeatable package of features well suited to a variety of applications.
