SMM-125-01-S-D Connectors, Interconnects

The SMM-125-01-S-D is a type of rectangular connector that is typically used in applications where space is limited and high reliability performance is required. It is a header for printed circuit boards and is generally used in applications such as telecommunications, datacom, PC/104, industrial, instrumentation, and medical equipment. The connector can be mated with an SMM-125-01-R-D receptacle, an SMM-125-01-S-D female socket, or a SMM-125-01-S-D male header.

The SMM-125-01-S-D is a single-row, straight, polarized connector with a 1 mm pitch and a maximum current rating of 0.5 Amp. The connector’s design resists against push-out and low-contact resistance. The contact system is designed to ensure both secure mating and reliable connection over the lifecycle of the product. The connector is also resistant to temperatures from -65°C to +125°C.

The working principle of the SMM-125-01-S-D connector is based on the phenomenon of electric conduction through contact between two metals. In this case, the connector’s positive and negative contacts are made of gold-plated copper with a layer of palladium and nickel beneath it. This combination of materials is corrosion-resistant and ensures good electrical current flow. When the connector is plugged in, the contact inside the receptacle contacts with the contact on the male header and completes the circuit, allowing electricity to flow and power the device.

The SMM-125-01-S-D connector is a reliable and durable connector that is suitable for applications where space is limited and high reliability performance is required. It offers maximum current ratings up to 0.5 Amp and resilient against a wide range of temperatures. Its corrosion-resistant contact system ensures good electrical current flow and long-term reliability. The combination of features makes the SMM-125-01-S-D perfect for telecommunications, datacom, PC/104, industrial, instrumentation, and medical equipment applications.
