Backplane connectors are essential in the modern electronics world. The contact types are an important component of the connectors, as they establish the connection between the components of the circuit. QR/P-XC-121(12) is an example of such a contact. This particular series of contacts is designed for use in industrial and telecommunications applications. It is a 2.5mm contact type, and consists of a male and female pair of contacts.

The QR/P-XC-121(12) is primarily used in multi-module and multi-slot backplanes where flat, watt density power and control lines need to be connected. The combination of the device\'s small size and flexibility makes it ideal for a variety of applications, including I/O, LED and other high-current applications.

In terms of performance, the QR/P-XC-121(12) can provide a reliable connection in either an industrial, communications or automotive environment. It has a temperature range of -55 °C to +125 °C, and can withstand vibrations up to 10g. The contacts also provide a good EMI/RFI shielding, which helps reduce any potential interference that may be caused by the device.

The QR/P-XC-121(12) connector utilizes a unique insulator design and an innovative contact construction. The insulator has a two-piece design in which the two halves interlock to ensure a secure fit. This design also allows for a higher mating and unmating force, while still providing low insertion and extraction forces. The unique contact construction features four contact elements that provide a controlled deflection and excellent durability, as well as excellent electrical performance. The contact elements are plated with gold to help increase their corrosion resistance and electrical conductivity.

The working principle of the QR/P-XC-121(12) is relatively simple. As the connector is mated, the four contact elements come into contact with each other. The contact elements provide a controlled deflection, allowing them to withstand a higher mating and unmating force. Once the contact elements have been mated, the insulation between the two halves ensures that the electrical connection is secure and uninterrupted.

In summary, the QR/P-XC-121(12) is a versatile and reliable contact type from the Backplane Connectors series. It has a unique insulator design and contact construction, providing a secure connection that is capable of withstanding a high thermal and vibrational environment. The contact elements are plated with gold to resist corrosion and provide superior electrical performance, and the robust design ensures the device is durable and reliable.
