Rectangular connectors are widely used in today’s electronic industry for the processing and exchanging of information. This type of connector includes arrays, edge types, mezzanines (board-to-board), and other types of connectors. One of the most popular among such connectors is 2-1658012-5. This article will explore 2-1658012-5’s application field and working principle.

2-1658012-5 is an edge type rectangular connector, designed for power/signal transmission. It is widely used in communication, automotive, medical, aerospace, audio/visual, and other industries. Its unique design features two rows of 50 pins spread over a 2.00 mm pitch. The connector is surface mountable, and can be used with corner, middle, and as a right angle connector. It can also be used as a low profile and scratch-resistant connector. This makes it a great choice for applications where clearance is limited, or where the environment is prone to scratching or environmental wear and tear.

The connector’s contact system comprises of a housing which supports two rows of 50 pins. The main material used to make the housing is dielectric material such as LCP (liquid crystal polymer). This material has excellent heat resistance and mechanical properties, thus allowing for high reliability and contact performance. The contact mating parts are made of beryllium copper and phosphor bronze which improves the mating and unmating force while ensuring superior electrical contact performance.

2-1658012-5 has superior signal integrity. Its transmission characteristics such as insertion loss, near-end crosstalk and return loss are excellent. The insertion loss is 0.02 dB, return loss is 18.82 dB, and crosstalk is -53.31 dB. These facts are approved by major certification standards, such as UL, CSA, VDE and others.

When using 2-1658012-5, it is important to note that the contact force should be between 0.8N and 1.2N. The connector should also be mated and unmated in a horizontal direction. Finally, the connectors should be reflow soldered at (240 – 250)℃, and the soldering time should be between (5 – 15) seconds. Doing so will ensure the connector life expectancy is hundreds of thousands of cycles, ensuring excellent performance and longevity.

In conclusion, 2-1658012-5 is an edge-type rectangular connector designed for power/signal transmission. It is widely used in many industries, and its transmission characteristics such as insertion loss, near-end crosstalk and return loss are excellent. It is important to note that the contact force should be between 0.8N and 1.2N, and it should be mated and unmated in a horizontal direction. The connector should also be reflow soldered at(240 – 250)℃, and the soldering time should be between (5 – 15) seconds. Doing so ensures the connector’s life expectancy is hundreds of thousands of cycles, thus ensuring excellent performance and longevity.
