ER8-120S-0.8SV-7H Application Field and Working Principle

ER8-120S-0.8SV-7H is a mezzanine-style edge type rectangular connector, which is commonly used to interconnect two printed circuit boards (PCBs). This connector has 8 poles, a contact spacing of 0.8 mm, with a rated current of 0.30A and a rated voltage of 150V AC. It also features a rated insulation resistance of 500MΩ, a housing that is made of 25Cr6Ni2Mo Steel, and a tin-plated brass contact. Its locking mechanisms include a retaining mechanism, a TPA (tape peen off) snap lock, and a tilt lock.

This connector has a wide range of applications, from telecommunications and computer systems to medical devices and industrial automation. It is also suitable for use in both dry and damp environments and can be mounted both horizontally and vertically. For added convenience, the connectors are available in various plated and unplated varieties.

Working Principle

The ER8-120S-0.8SV-7H mezzanine-style rectangular connector works by connecting two printed circuit boards directly, ensuring a strong and reliable connection. The connection is enabled by the abrasion-resistant contacts on each side of the connector. The contacts protrude from the connector and are designed to provide an electrical connection between two PCBs when they are connected. This ensures that signals and power are passed between the two boards in an efficient manner.

The ER8-120S-0.8SV-7H features a unique locking mechanism that allows it to hold two boards together securely. This locking mechanism works by using two pins that fit into one another, ensuring that the connectors are firmly held in place. The locking mechanism also prevents the connectors from loosening due to vibrations, ensuring that they remain tight at all times.

Conclusion

The ER8-120S-0.8SV-7H is a mezzanine-style edge type rectangular connector that offers a reliable connection for two printed circuit boards. Its wide range of applications, from telecommunications and computer systems to medical devices and industrial automation, makes it ideal for many applications. Its abrasion-resistant contacts and locking mechanisms ensure that the connection remains secure, preventing signal loss and power interruption.
