D-Sub connectors are digital cables designed to transmit data over electronic systems. They are used for a variety of connectivity purposes such as industrial automation, robotic systems, process control, video applications, and multi-drop communication. Their popularity has led to multiple types of D-sub connectors being produced, such as high-density, miniature, and EMI shielded varieties. The 748953-1 connector is a high-density type that features an EMI shielded design.

The 748953-1 connector offers a robust and reliable connection that can carry connections between a variety of electronic components. It has a maximum current rating of 15A at 250V AC and an operating temperature range of -25 to 85 degrees Celcius. The connector is designed to mate with compatible D-sub variants, such as the 748953-2 and 748953-3.

The 748953-1 D-sub connector features 32 total pins and two different levels of shielding. The first level of shielding is made of a shielded metal shell and an o-ring that surrounds the pins and secures the connection. The second layer of shielding is made of plastic and is intended to reduce EMI interference. The contacts are metal-coated to help prevent corrosion and resist corrosion.

The 748953-1 connector is designed for industrial automation, robotic systems, process control, video applications, and multi-drop communication. It is suitable for data transfer between computers and other electronic systems, as well as serial communication between devices. The connector is designed to be easily inserted and removed from panels, making it particularly suited for applications that require frequent connections or disconnections.

The working principle of the 748953-1 D-sub connector is relatively simple. In order to establish the connection, the pins on the male connector must be inserted into their counterparts in the female side. This ensures that the two mating parts fit correctly and create a secure connection. The connection is then reinforced by the shielding layers, which help to protect the data from interference and reduce EMI interference.

In summary, the 748953-1 D-sub connector is a reliable and robust connection solution designed for industrial automation, robotic systems, process control, video applications, and multi-drop communication. The connector has a maximum current rating of 15A at 250V AC and an operating temperature range of -25 to 85 degrees Celcius. It has 32 total pins and two layers of shielding – a metal shell and o-ring combination, as well as a plastic shielding layer – and is designed to easily mate with compatible D-sub variants. The working principle of the connector is straightforward and simple, as all it requires is for the male pins of the connector to be inserted into their counterparts in the female side.
