JC21EJ2-BRB20E

Memory Connectors – PC Card Sockets are a type of electrical connector, an interconnected network of components used to interface electronic devices and systems. They enable a connection between two components with difference electrical properties, allowing data to be exchanged between them. The JC21EJ2-BRB20E is a memory connector which falls into this category – here, we look at the application field and working principle behind this important device.

Applications for the JC21EJ2-BRB20E

Memory connectors are generally used in the integration of electronic systems, and this particular model is no different. It is commonly used in a wide range of applications due to its durability, low profile, as well as its reliable functionality. These include, but are not limited to, automotive, medical, military, industrial, instrumentation and aerospace systems. In automotive applications, for example, this connector can be used in seat heating and climate control systems, in order to connect the power supply to the sensors and controls.

This same connector has also become increasingly integral to portable computing devices in military, industrial and commercial use. Its low profile design allows it to be used in laptop and PCMCIA (Personal Computer Memory Card International Association) type cards, as well as a variety of the latest MIL-STD interfaces and systems. This makes the JC21EJ2-BRB20E well suited to rugged applications in military and aerospace systems when compared to standard memory connectors.

Working Principle Behind the JC21EJ2-BRB20E

The key feature of the JC21EJ2-BRB20E is its reliable mechanical and electrical performance. It is rated up to 6.6Amps continuous current at 50 Volts, and has a contact resistance of 30mΩ (maximum). This connector is capable of up to 500 insertions and extractions, and has also been subjected to salt spray and harsh vibration tests to ensure it is able to withstand harsh environmental conditions.

The connector also has a two-step mating operation, which allows for a precise linear connection between two components. When mated, the contact spring internals are engaged, which ensures that the maximum amount of connection is achieved. On connection, the spring inside each connector grabs onto the contact pins, holding them in place and providing a reliable connection.

The JC21EJ2-BRB20E also features a two-pin grounding system that helps with emission control and environmental protection. This ensures that no electromagnetic interference (EMI) is created by the connectors. In addition, the connector also features a unique locking mechanism, which is designed to prevent accidental decoupling during operation.

Conclusion

Memory Connectors – PC Card Sockets contribute to the reliability and performance of a wide range of electronic systems, and the JC21EJ2-BRB20E is a prime example of this. Thanks to its durable construction and reliable electrical performance, this connector is well suited for automotive, medical, military, commercial, industrial and aerospace applications. This connector also offers a variety of features, such as its two-pin grounding system, locking mechanism and two-step mating operation, which all contribute to its overall reliability and performance.
