Backplane connectors are specialized connectors that provide a mechanical interface for communication between backplane boards and daughter boards in electronic systems. 0461121203, also known as Positronic, is a backplane connector from Molex, Inc. that is typically used in harsh environment applications. This article will provide an overview of 0461121203, including its application field and working principle.

Backplane connectors play an important role in the design of electronic systems by providing a reliable connection between backplane boards and daughter boards. 0461121203 is a high density vertical backplane connector that can accommodate up to 32 signal contact pairs at the same time. It is a single-row connector with 4 rows of contacts with 8 positions on each row. The contacts are rated for 5A current carrying, making it suitable for applications with high DC power requirements. It is also designed with a polarized header, which prevents improper connection due to mismatched polarities. In addition, it is equipped with a locking feature that ensures a strong connection between the mating halves and prevents them from being accidentally disconnected.

0461121203 is designed for use in harsh environment applications, such as off-road vehicles and industrial equipment. It is rated for a temperature range of -55°C to +125°C and provides durable, reliable performance in extreme temperature environments. It is constructed from a rugged Polyamide compound, which makes it resistant to dust, moisture, and various chemicals. In addition, the connector is RoHS compliant and is UL 94V-0 rated, ensuring it meets industry standards for safety and quality.

The working principle of 0461121203 is similar to that of other backplane connectors. When the plug and the receptacle are mated, the contacts on both sides make electrical connections. The signal pins are connected to the traces of the backplane board, while the power pins are connected to a power source. As the current flows through the connector, it creates an electromagnetic field around the contacts, creating a return path for the current. This allows the connector to transfer electrical energy between the mating components.

0461121203 is a high-performance backplane connector that is suitable for use in harsh environment applications. It is designed to meet industry standards for safety and quality, and is capable of handling up to 5A of current. It is a reliable and durable solution for connecting backplane boards and daughter boards in applications with extreme environmental conditions.
