Rectangular Connectors - Headers, Male Pins, used in a wide variety of applications and projects, are made of hard-wearing and sturdy materials. The 641121-2 series feature dual-row headers, machined from brass with gold-plated durable terminals and with either male or female pins.

The 641121-2 connectors are designed for use in harsh environments with high slip and vibration, making them ideal for use in aerospace, medical, industrial, and automotive applications. The 641121-2 has a Termination Force of 45N, an Insulation Resistance of 50MΩ, a Dielectric Withstanding Voltage of 250V, a Contact Resistance of 20mΩ, and an Electrical Endurance of 1000 cycles.

The 641121-2 series is easier to mate with devices thanks to its Push-In design. It also offers improved shielding compared to standard Push-In connectors, reducing EMI/RFI. The dual-row arrangement of contacts also gives superior durability to single row versions, making the 641121-2 ideal for high-vibration and high-reliability applications. The high quality insulation compensates for temperature change, while the high number of mating cycles ensures reliable connections.

The 641121-2 takes vertical placement in a straight line with a 30-degree angle that helps secure the second row of terminals. Six sizes of this connector are available between 4 and 12 pins with an insulation rating of 300VAC. It is also offered with snap or leded box mounting formats. The board spacing on the 641121-2 is 2.54mm, while the connector spacing is 5.08mm. This spacing feature secures signal integrity, saves board space, and reduces crosstalk.

The 641121-2 series also offers a choice of 2 grounding systems. The first system consists of a slotted aluminum end plate plus a grounding post that simplifies mounting the assembly on a ground plane. The second system includes a grounding plate connector which helps to avoid spurious EM radiation.

The 641121-2 is highly resistant to vibration and shocks, while its ability to rotate allows for simple mounting on circuit boards, providing extra space for other components. This connector is also reliable and cost-effective, and durable enough for high vibration environments.
