Backplane connectors are used in a wide range of PCB assemblies. The 70238-197LF is specifically designed to provide improved signal integrity in backplane assemblies. It includes a push-pull connector system with 2mm pitch and is available in a variety of configurations. Its function depends on application, like supporting a control unit or monitoring system, but its general principles are the same. This article will discuss the general principles of the 70238-197LF and its application field.

Properties

The 70238-197LF is a two-pole micro-lock push-pull type connector system. Its features include:

• Stagger stacked contacts
• 22 circuits
• 2mm pitch
• Available in surface-mount or through-hole configurations
• Polarization to ensure correct mating
• High reliability

Working Principle

The 70238-197LF is a backplane connector, meaning it interconnects multiple printed circuit boards within a single system. It does not connect the boards with one another but with each other\'s internal circuits. When mated or connected to another connector, the contacts within the 70238-197LF create a secure electrical connection that reliably transfers signals and power between the boards. This allows for efficiently passing signals between devices with minimal signal interference or loss.

The 70238-197LF has two configurations, surface mount and through-hole. In both configurations, the connector includes a series of staggered stacked contacts that are engaged when the connector is mated or connected to another connector. These contacts are precision machined to ensure reliable, low-resistance contact and minimized signal interference. The connector also includes a positive locking mechanism and polarization to ensure correct mating during assembly. This ensures that the signal transfer is performance optimized and is consistent between components.

The 70238-197LF also includes several features that focus on robustness and dependability. These features include dust sealing, shrouded contacts, strain relief features, and ESD protection. These features help the connector provide reliable electrical connections even in harsh environments where dust, moisture, and mechanical stress may be present.

Application Field

The 70238-197LF is most commonly used in backplane assemblies in applications such as communications, industrial systems, and automation control. Its push-pull connector system, with its 2mm pitch, is ideally suited for use with high-speed signal transmissions, and its 22 circuits provide high-density signaling for complex backplane architectures. In addition, the connector’s dust sealing and ESD protection features make it a viable solution for use in harsh environments.

The 70238-197LF is also suitable for use in backplane assemblies that use multiple cables. The connector’s push-pull design ensures that the cables remain securely mated to the connector while providing reliable electrical connections regardless of cable type and size. Additionally, the use of strain relief features helps to protect the life of the cables and ensure that they remain securely mated to the connector.

The 70238-197LF is an ideal solution for applications requiring high-speed, high-density backplane assemblies. Its features ensure reliable, low-resistance electrical connections between boards and, when combined with the dust sealing and strain relief features, make the 70238-197LF an ideal choice for even the harshest environments.
