Rectangular Connectors - Arrays, Edge Type, Mezzanine (Board to Board) such as 74217-101, provide excellent strain relief and mechanical resistance. These connectors are a perfect solution for connecting two or more printed circuit boards together in a single board application.

74217-101 types are constructed with two identical plug and socket halves, each containing a plug-and-socket array of male and female pins arranged in a straight line along the edge of the connector. The arrays have a typical staggered length configuration, and each plug and socket half housing can contain up to 50 pins. This makes them well suited for applications with a large number of pins, while ensuring that the connection is securely fastened, and that strain relief and mechanical stress are minimized.

Connectors of this type come in several standard sizes ranging from 7 to 39 pins in 2.54mm pitch, and feature multiple mounting options including: front-panel mounting, surface mount, and DIN-rail mount. They provide fast, reliable, and secure connections, and are resistant to moisture, dust, and vibration.

74217-101 types are typically used in applications such as embedded systems, consumer electronics, automotive and industrial control systems, industrial automation, automatic photo booths, communication and telecommunication systems, computer-aided designing (CAD), instrumentation, medical imaging, and military applications.

In terms of specific working principle, 74217-101 connectors, extensively used in low-voltage, low-power applications, use a simple design to ensure reliable current and voltage transfer. Inside the plug and socket half of the connector is a mating row of pins which is either brought directly into contact with each other or that is brought into contact through the use of a connecting pin. Every contact pin is electrically connected to the device’s internal circuitry. When the two halves are plugged together, power is supplied to whatever device is being powered. This ensures reliable and safe current and voltage transfer.

Moreover, the plugs and sockets of 74217-101 rectangular connectors are designed with a unique anti-rotation feature, which prevents the connector halves from unscrewing even during extended periods of vibration. This allows for secure connections in applications with heavy vibrations and ensures that the connection between the devices remains intact.

In conclusion, 74217-101 connectors provide a dependable, low-cost solution for connecting multiple printed circuit boards in high-connectivity applications. They are ideal for applications that require a relatively high number of pins, and due to the anti-rotation feature they provide a secure connection even when exposed to extended periods of vibration.
