Rectangular Connectors - Headers, Receptacles, Female Sockets

Rectangular connectors are a type of electrical connector used in a variety of applications that require a small, lightweight solution that can handle higher pin counts. They are available in size ranges with one, two or three rows of pins and in between 10 and 100 pins. The pins are supported by round posts that are straight or slightly angled.The 09-52-3121 connector is a three-row, twelve pin version of this type of electrical connector. It is typically used in PCBs for through-hole and surface mount applications. The connector is available with a straight or right angle termination style. It features anti-mate locking hooks that prevent movement of the header within the socket for secure installation. It has a high current rating and is available in three different gender types – male, female and non-gender.The female version of the 09-52-3121 has three rows of twelve pins. The pins are spaced 0.100” and the body is around 0.100” to 0.150” thick. It has an overall length of 0.670” with a maximum width of 0.611”. The male version of the 09-52-3121 has the opposite orientation and is generally shorter in overall length with a maximum width of 0.618”.The working principle of the 09-52-3121 connector is based on the provided power between pins and receptacle. The pin of the connector is in contact with a corresponding receptacle loaded on the board. Due to high contact pressure between the two elements energy is transferred between them. This creates an electrical connection that enables the flow of current when desired.The 09-52-3121 connectors are typically used in a wide variety of applications including automotive, medical, computer, telecommunications and industrial. They are often used in power supplies, routers, switches and in circuit boards. They have the capability to withstand higher current than other types of connectors and are able to handle greater numbers of pins and can carry up to 5 amps.Rectangular connectors are a very useful and reliable way of transferring energy from one source to another. The 09-52-3121 connectors are particularly useful in higher pin count applications that demand a lightweight design, quick installation and a high current rating. This type of connector is popular in many industries and is becoming increasingly more important in our world.
