  SMS4PHGE4 is one of the most widely used rectangular connectors used in the electronics industry. It is a low-cost connector with two basic components, the header and the male pin. This connector is available in different configurations to meet specific application needs. For example, some designs have more pins in order to accommodate multiple digital devices, while other designs have fewer pins and are used for single devices or less complex electrical systems.

  The header of the SMS4PHGE4 is an insulated plastic block with two rows of terminals. Each terminal has a central pin which fits into the corresponding male pin. On each side of the block, there is a keyed slot to ensure the correct mating and positioning of the pins. The block is designed with an alignment slot to assist in the proper insertion of the male pin.

  The male pin is a cylindrical metal part which slides into the header and engages with the keyed slots. It is often made of brass or copper for superior conductivity. The pin is also protected from corrosion and outside influences by an insulated plastic sleeve. The sleeve is attached to the pin via crimped or threaded connections and also provides strain relief.

  The SMS4PHGE4 connector is designed to meet the needs of a wide range of application fields including telecommunications, computer systems, automotive electronics, and medical electronics. Its low cost makes it a popular choice for many applications. Its strong, reliable electrical connection is another factor that makes it highly attractive.

  The working principle of the SMS4PHGE4 connector is based on the mating of two dissimilar materials. The first is the insulated plastic block that houses the terminals and the other is the male pin which engages with the terminals. When the two are inserted into each other properly, the terminals make contact with the pin which creates an electrical connection. The pin and block are designed to remain securely connected, ensuring reliability and durability.

  The SMS4PHGE4 connector is an ideal choice for many applications due to its versatility and simplicity. Its low cost and reliable connection also make it attractive to users. While it is essential to use the proper installation techniques to ensure the connector’s performance, its design features make it relatively easy to install and integrate into many electronic systems.
