ARINC 4-208973-1 is a type of backplane connector that is becoming increasingly popular for joining electronic components. It’s most commonly used in embedded systems, Fanuc control systems, industrial automation systems, and the aerospace and defense industries. It is recognized for its high reliability, with fast response times, good electrical insulation, and low insertion force. The 4-208973-1 is also distinguished for its versatile application, with the ability to be used in bus-type networks.

Designed to meet the requirements of ARINC 817, the 4-208973-1 is a family of backplane connectors that employ a two-piece design, with the male version having a pair of side locking tabs. This design allows for a secure and easy mating, minimizing the chances of coupling failure. The contact blocks used for the connector are gull wing SMT blocks, which provide an electrical bridge between the two components.

In addition, the 4-208973-1 connector includes an integrated shielding feature that guards against EMI/RFI interference. This ensures signal integrity by reducing crosstalk, connecting faults, and other signal-related issues. Additionally, the connector features signals for ground (GND), power (VCC), and ground Return (EED). Other associated wires can be connected to either the +VCC or GND within the application.

The 4-208973-1 application fields are wide-ranging, as mentioned earlier. It is often used in embedded systems such as automotive, ATM, healthcare equipment, mobile devices, and even home automation systems. due to its high reliability and fast response times, these connectors are excellent for use in industrial systems where precise signals are essential. Additionally, the 4-208973-1 connector is great for aerospace and defense applications as well, due to its shielding and EMI/RFI protection.

In terms of working principle, the 4-208973-1 works using a pin-and-socket connection. Once the connecting pins are aligned properly, the connection is secured with a latch that is easily activated with a short press or slow release. The contact blocks then create an electrical bridge between the two components, allowing signals to be passed from one to the other. The shielding feature then guards against EMI/RFI interference.

Overall, the 4-208973-1 backplane connectors are a highly reliable solution for joining electronic components. Their two-piece design and integrated shielding feature make them perfect for a wide range of applications. With an easy-to-use pin-and-socket connection, these connectors possess the necessary features to ensure secure, fast, and accurate signal transmission.
