Rectangular Connectors - Headers, Male Pins - 146261-8 Application Field and Working Principle

146261-8 is a type of rectangular connector with two rows of pins. It consists of two headers, each with two rows of vertical pins perfectly fit with a mother board. The headers have passivated finish to resist corrosion and dust, which make it suitable for most modern applications like computers, low-voltage and medium-voltage electronic boards, automotive and industrial process control systems.

The application field of 146261-8 includes computers, low/high voltage electronic boards, automotive and industrial process control systems. The working principle of 146261-8 is quite simple. The two headers are lined up with two rows of pins that are fit into an appropriate port in the mother board. Each pin performs a specific task or role based on the power supply, data signal and voltage provided from the board. The pin is connected to the conductor that transports the current from power supply or data signal from the source and the receiver of the signal.

The most commonly used connector in the 148261-8 application field is the EIA/JEDEC rectilinear connector. EIA/JEDEC conform to the EIA/JEDEC standards that determine the physical dimensions and outlines of electronic components. The EIA/JEDEC rectilinear connector is made to withstand the rigors of repeated mating cycles and harsh environmental conditions. This connector provides superior contact performance, resistance to nuisance disconnects, and protection against contact failure due to various environmental conditions such as shock, vibration and temperature extremes.

The EIA/JEDEC rectilinear connector has surface mount and through hole mounting pads that depend on the board design. The EIA/JEDEC rectilinear connector is soldered to the mother board at the appropriate location. The connector also has special markings that indicate the orientation of the connector pins that need to be plugged into the header with proper alignment. This ensures the correct usage of the connector, eliminates waste of time and money due to improperly inserted connectors.

The types of conductor materials used in the 146261-8 application field includes copper, brass, nickel and tin plating. The copper conductor has low electrical resistance, low impedance and offers high thermal conductivity. The nickel conductor has low electrical resistance and offers high surface conductivity. The brass conductor has excellent electric and air resistance and offers good wear and fatigue properties. The tin plating allows improved solderability and contact resistance.

In summation, the 146261-8 is a type of two row rectangular connector with two headers. This connector is widely found in computers, low/high voltage electronic boards, automotive and industrial process control systems. The connector is manufactured following the EIA/JEDEC standards and is soldered onto the mother board at the appropriate location. The material used for the conductor may be either copper, brass, nickel, or tin plating. The 146261-8 connector is superior in contact performance and reliable in withstanding shock and vibration.
