Rectangular Connectors - Headers, Receptacles, Female Sockets, are essential components used to join two systems or subsystems for the purpose of communication, exchanging data or power. They come in varying shapes and sizes and can be made from a range of materials. Of particular interest is the 3-535542-4 rectangular connector, a standardized device used mainly in the telecommunication industry. In this article, we’ll examine the application field and working principles of the 3-535542-4.

The 3-535542-4 rectangular connector is a type of through-hole plug connector favored in the telecom sector. Its 9-contact configuration allows for reliable connection and controlled impedance matching when used in combination with a corresponding 9-pin male header. The connector also features two pre-stripped leads that are terminated and sealed into the backshell. This part is manufactured to DB9_CISPR11 electrical specifications, which makes it suitable for use with low/medium signal frequencies of up to 4GHz. Its thick-wall construction helps protect the contacts and ensure reliable signal integrity.

In terms of applications, the 3-535542-4 is suitable for a variety of tasks, ranging from data transmission to power distribution. It can be found in a variety of telecom relationships, such as wired telephone lines, cell phones, cable TV, and satellite systems. It’s also used in industrial applications, including pneumatic systems, audio equipment, and computer systems. Additionally, apart from having a long service life, the connector offers precise engineering dimensions for easy assembly within complex systems.

The principle of operation for the 3-535542-4 is quite simple. The connector is inserted into a mating receptacle or header and the rear cable is secured by a pair of pre-stripped wires. Inside the contact area, each metal contact is spring-loaded and receives electrical signals from pins on the associated printed circuit board (PCB). When the signal passes, the connector enables signal transduction between the two systems or subsystems.

In terms of performance, the 3-535542-4 offers impressive levels of signal "strength" and interference protection. As mentioned previously, this connector is produced to DB9_CISPR11 electrical specifications. This utilizes a combination of design elements, including a stiffened backplate, partially insulated contacts, heavy-duty contact retention, and integral cross-talk protection for minimized internal interference. This combination ensures reliable signal transmission between the two systems.

Due to its reliability, easy installation, and a long service life, the 3-535542-4 has come to be a popular choice among telecom businesses and industrial settings. Its 9-contact configuration allows for maximum data and power transmission while its sturdy build and protective features ensure signal integrity. In terms of cost effectiveness, the connector is on par with other similarly sized, DB9_CISPR11-compliant parts. All things considered, the 3-535542-4 is well-suited to a wide range of applications.
