3-87961-4

Rectangular Connectors - Headers, Receptacles, Female Sockets are important parts of any electric device or machine. Steady power transfer and signal connection are required when these products are utilized, thus it is important for the user to fully understand its application field and working principle. This article will explain in detail about the application field and working principle of 3-87961-4.

3-87961-4 is a type of rectangular connector. It has pin contacts and requires two pc-board involved in mating. This product utilizes IDC connection technology and is suitable for ribbon cables. It Connects and disconnects with a cable tie.

The 3-87961-4 connector can be used for home appliances, security systems, control panels, audio/visual equipment, computers, and other applications for signal or power transfer. It is compliant with RoHS directive and UL94V-0 standards.

The 3-87961-4 features a 1 mm pitch, a 3R or 5R to 10R wire range, and a pull rating of 4.1 kgf (min). It is also electromagnetic interference (EMI) shielded and has low electrical resistance with good heat resistance and good solderability. It has a high current carrying capacity of 10A. It is commonly available in two different color, black and green.

In order to use the 3-87961-4, a couple of requirements must be met. The use of a flexible flat cable is necessary as flexible wires require special insulation. Also a dual-row, 40-position connector receptacle and header will have to be utilized, as well as two pc-board. The header contacts come in two different sizes, 0.64mm and 0.5mm.

The 3-87961-4 operating principle is fairly straight forward. When the connectors are mated, the insulation displacement contact (IDC) is triggered. This triggers the inner contacts in the connector to move and make electrical contact with the edge of the ribbon cable conductor. When the connector is removed from the pc-board, the contact is released and the connection is broken.

Additional features of the 3-87961-4 are its resistance to temperature variations, electrostatic discharge (ESD) protection, and good electrical shielding. The temperature range for the 3-87961-4 varies from -40°C to +105°C, depending on the wire size and the current processed. In terms of ESD protection, the 3-87961-4 meets the requirements stated in IEC-950, ensuring that electrostatic charges are safely discharged away from sensitive components.

The 3-87961-4 rectangular connector is a versatile device used for transferring power and signals and making connections with neutral terminals. Its application field and operating principle are well understood by users who can properly configure the connectors to satisfy their desired needs.
