Rectangular Connectors - Headers, Receptacles, Female Sockets

The SMM-120-02-S-S-20-TR is a 120-pin, top-mount connector that covers a broad range of uses and applications. These rectangular connectors—also called headers, receptacles, and female sockets—are found in a range of devices and products and can be used as a versatile connection solution. The parts are easy to install and maintain, and offer consistent performance.

Application Fields and Working Principle

The most common applications for this type of connector are in computers and other devices with high-density connector requirements. It is suitable for wire-to-board, wire-to-wire, and board-to-board connections. It is also ideal for applications in industrial control, communication systems, computer hard drives, military equipment, and in-vehicle applications. The 120 pins offer excellent contact reliability in environments with vibration, shock, and moisture.The working principle of a female socket is fairly simple—it consists of a housing that includes 120 terminals and contacts that are either soldered into a PCB or soldered directly onto wires. An additional protective sheet is then inserted to secure the contacts in place. The pins on the mating male connector fit into the female socket’s contact cavities to create a secure connection. This design ensures optimum signal and power transmission.

Design and Materials

SMM-120-02-S-S-20-TR connectors are designed to last and feature many of the same features as standard DIN-rail mounting. The terminals are gold-plated over phosphor bronze for reliable electrical and mechanical connections, and the contacts are rated at 2 amp. The body is made from a durable plastic material that has a WV1 flammability rating, and it also includes strain relief to reinforce the wire connections.The mating male connector is designed to fit securely into the female socket. It has 120 pins that are constructed from phosphor bronze and plated in gold. The pins are sealed to provide protection from dust and moisture, and the body is made from tough plastic.

Benefits

One of the main advantages of using this connector type is that it is a reliable connection and can sustain high connection loads. The male connectors provide stable electrical and mechanical performance over a wide temperature range, and they are designed to be consistent to ensure effective performance. Additionally, these connectors require minimal space for installation, which helps reduce the overall cost of the product. Another benefit of using this type of connector is that it is easier to maintain than other types of connectors. It can be cleaned in a variety of ways such as ultrasonic or alkaline baths, and it is easy to replace parts. Furthermore, it is designed to be cable-tie resistant to ensure a secure fit. Finally, the 120-pin design makes it easy to configure the pins for various applications. This, in turn, makes the connector suitable for a range of devices and products.

Conclusion

The SMM-120-02-S-S-20-TR is a highly reliable and versatile rectangular connector with many uses. It is easy to install and maintain and provides consistent performance. Its 120-pin design allows for a wide range of configurations and makes it suitable for high-density connections in computers and other devices. It is also resistant to cable ties for added security, and features a design that provides protection against dust and moisture. It is a great choice for a variety of applications.
