Rectangular connectors are a type of electrical connector used for various applications, often in high-density packaging, such as electronics where space is a constraint. SMS9PH4D-28 connectors are one such type and are typically used for high-speed signaling applications.

The SMS9PH4D-28 are headers, male pins, which mate with female sockets to provide reliable electrical connections and superior mechanical performance. These connectors feature a top-entry orientation for soldered systems and are composed of separate pieces of polished machine contacts, a plastic insulator, and integrated support posts for secure mounting in the PCB. The header’s opening and closing operation can be customized according to the customer’s application needs.

The body of the SMS9PH4D-28 is made of thermoplastic UL94V-0 rated material, providing good insulation and protection from electric shock. The contact is machined of brass with nickel plating for superior signal integrity and also for better durability. The contact point is also gold-plated for enhanced corrosion protection. The pins have an insertion force of maximum +1N for easy assembly and are capable of withstanding up to 200 insertions and removals without compromising the connection reliability. Moreover, the insulated top of the male pin prevents short-circuits.

SMS9PH4D-28 connectors are designed for high-speed and long-distance applications where data transmission speed is of utmost importance. They are rated for a voltage of 150VAC, a current capacity of 4A, and a maximum operating temperature of -55℃ to +105℃. This makes them suitable for a wide range of applications, such as computer and telecommunications systems, consumer electronics, and automotive. The contact retention force of 0.3 N ensures reliable long-term mechanical connections.

The SMS9PH4D-28 connector’s working principle is based on the law of electrical conduction. The copper pins allow current to flow through the wiring, while insulating material provides electrical insulation to protect the cable from shorts and open circuits. Connectors act as a medium enabling the transfer of energy from one component to another. It is important that the different components are correctly aligned to avoid short-circuiting and other related problems. The pins are also designed to provide maximum force contact to ensure reliable signal transmission.

In summary, the SMS9PH4D-28 rectangular connectors are suitable for a variety of applications due to their superior performance and reliability. The pins have great electrical insulation, are resistant to corrosion, and are capable of withstanding high temperatures. The connectors provide reliable long-term electrical connections due to their high contact retention force. Connectors allow energy to be transferred from one component to another without short-circuiting or other related problems.
