Rectangular Connectors - Housings

The SMA12PD3 is a modern rectangular connector designed for a range of applications where secure connections are required. The SMA12PD3 is a three-pole rectangular connector which is designed for the robust mounting and electrical interconnecting of a variety of cable assemblies. The connector has proven itself to be reliable and robust in a wide range of industrial and commercial applications, whether it be used for machines, equipment, or even consumer products. It is highly reliable and durable due to its metal housings and inner contacts, and also features a unique protective metal backshell design.

Application Field

The SMA12PD3 is ideally suited for the building and connecting of panel mount assemblies, domestic and commercial equipment, audio visual equipment, industrial equipment, consumer electronics, and computers. It’s also often used for the connection of motor control panels, surge protection, and signal processing equipment. Additionally, its design features allow it to be tightly connected even in the harshest environments.

Working Principle

The SMA12PD3 operating principle relies on the rotation of a spring clip, found on the inner body of the connector. As the spring clip is rotated, it is then pushed outward by the inner contacts. This increases the contact pressure while allowing for easy assembly and removal. Additionally, the spring clip keeps the contacts in place ensuring excellent reliability with a tight and secure connection.

The inner contact of the SMA12PD3 is constructed of high quality metal. This ensures a high degree of resistance to electrical and mechanical shock, as well as providing surprisingly high levels of water and dust resistance. The external design features a PVC sleeve for protection, which is itself fitted with a removable front cover with a positive locking mechanism.

In conclusion, the SMA12PD3 is an excellent example of a modern rectangular connector housed in a robust metal shell with a protective PVC sleeve. It is ideal for the building and connecting of applications where secure connections are required. With its reliable contact design and secure receptacles, the SMA12PD3 provides a solid and highly durable connection in all conditions.
