552118-1 Connectors, Interconnects

D-Shaped Connectors – Centronics

D-shaped connectors have been around for decades, and are still found in many electronics applications. The 552118-1 is an example of a standard Centronics connector, also called an IEEE-488 or 488.2 connector. Originally popularized as an expansion interface in personal computers, the Centronics connector is still widely used for data transfer and power cable connections.

Application Field and Working Principle

The 552118-1 is a classic D-shaped connector with two complete sets of 37 conductors. The primary usages of these connectors are for data connections, either as a direct interface or within devices, and for power connections between external power sources and the device. The D-shaped connector is attached to the device by four allen screws and then plugged into the power source that will provide the needed voltage for the device.

The 552118-1 connector includes male pins on one end that are used to connect the device. In most cases, they are inserted into an interior socket that typically has 37 female contacts. When the pins are connected, the device will get a corresponding electrical signal. From the source side, the connector is typically connected to a power transformer to provide a consistent voltage to the device. The integrated circuits of the device then use the transformed voltage to run the application.

Not only does the 552118-1 connector accommodate a large number of conductors, but it is also designed for reliable signal transmission. This is accomplished through an array of pins that are specifically located on the circumference of the connector, which prevents crosstalk or signal interference between two circuits. The snug fit of the connector also ensures reliable contact between the two sides. The contacts are designed to be corrosion-resistant, and the pins are spring-loaded into the interior socket to ensure a tight fit.

The 552118-1 is also designed for easy installation. A notch is provided on the circumference of the connector to ensure the pins are properly aligned with thesocket of the device, and guiding notches are provided on the face of the connector. This allows for quick and adequate insertion and connection of the device.

In addition to power and data connections, the 552118-1 connectors can be used in a variety of situations. They are commonly used in medical imaging systems, testing and monitoring equipment, and communications systems. They are also often employed in audio-video equipment, motor controls, and electrical controls.

D-shaped connectors have been around for a long time and, due to their durability and reliability, they remain a popular choice for many applications. The 552118-1 is a versatile connector that is widely used in power and data connections, and is designed for easy installation and reliable performance.
