91911-31221 Application Field and Working Principle

Rectangular connectors are in wide use in electronics industry in the form of edge type, mezzanine and array connectors. The 91911-31221 rectangular connector is a high quality, widely used product, suitable for various devices and applications. This article will discuss the application field and working principle of the 91911-31221 rectangular connector in more detail.

Application Field

The 91911-31221 high quality rectangular connectors are mainly used for a wide range of electronic devices, especially those with advanced signal processing capabilities. The connectors can be used to connect boards, I/O devices and communicate with other systems. The 91911-31221 also offers great resilience to dust and high temperatures, making it suitable for industrial environments. In addition, it maintains a high level of data integrity and supports Gigabit Ethernet speeds, making it suitable for high speed data communication.

Working Principle

The 91911-31221 rectangular connector consists of two identical halves, joined at the centre. Both halves of the connector contain multiple contact pins which are arranged in parallel so that they line up with the corresponding pins on the mating connector. When two connectors are joined, each contact pin on one connector is lined up with a corresponding contact pin on the other connector, forming an electrical circuit.

The two halves of the 91911-31221 connector are designed to fit together perfectly, with a slight overlap between the contact pins on each half. The format of the connector allows for a snug fit when the two halves are joined. This ensures that a reliable and secure connection is formed.

The 91911-31221 rectangular connector has an operating temperature range of -30℃ to +85℃, and a contact current rating of 2A per pin. The operating voltage is rated at max. 50V. The contact resistance is typically 50mΩ max, and the insulation resistance is 5000MΩ min. It has a dielectric strength of 1500VAC for 1 minute and 500 MΩ min at 500V DC.

Conclusion

The 91911-31221 high quality rectangular connectors are designed for a wide range of devices and applications. They are reliable connectors that provide a secure connection with minimal contact resistance. They are suitable for communication at Gigabit Ethernet speeds and also resilient to dust and high temperatures.
