Introduction

Rectangular connectors are generally classified into four main types: arrays, edge type, mezzanine (board to board), and subminiature. The application area and working principles of 91910-21421 rectangular connectors explain why they are a suitable solution for many applications.

Applications

91910-21421 rectangular connectors are mainly used for the following types of applications:- Power Supply Connectors: The powerful 91910-21421 connectors are suitable for power supply applications that require a reliable connection in a highly compact form-factor. - Heater Connectors: 91910-21421 connectors are often used as heater connectors due to their high current carrying capacity and insulation resistance.- Computer peripherals: These connectors are also suitable for computer peripherals, offering good shielding from electrical interference.- Industrial Automation: A wide variety of 91910-21421 connectors are also suitable for use in industrial automation applications due to their durability and reliability.

Working Principle

The working principle of 91910-21421 rectangular connectors is based on conducting electrical current between the two mating connector ends. The connectors feature a diecast aluminium mating head and a Zinc die-cast shell, which allow them to securely mate and provide a high degree of electrical shielding.The connectors are also designed with a number of metal contacts that are press-fitted into the connector. These contacts spring out to make contact with the mating end when the two parts are mated, thus carrying the electrical current. A durable spring contact ensures reliable contact and low contact resistance in all operating temperatures.

Conclusion

91910-21421 rectangular connectors are a reliable, low-cost solution for many applications. They offer good shielding from electrical interference, feature a durable spring contact that ensures reliable contact and low contact resistance, and are suitable for use in power supply, heater, computer peripheral, and industrial automation applications.
