Rectangular Connectors - Headers, Male Pins

The 961111-5500-AR-PT series of connectors is specifically designed for applications that require a high contact density and compact size. It is a discrete header and male pin combination that is well suited for a variety of applications. The connector has a total of 55 pins spread across a 2 row package and the maximum operating temperature is 125°C.

Application Field

The 961111-5500-AR-PT is designed to be used in many industrial and commercial applications. It has been tested to meet the requirements of MIL-PRF-55850F and UL94V-0 specifications, making it ideal for applications that require these standards. Additionally, the connector can also be used in transportation, communications, power supplies, computers, and other applications.

Working Principle

The 961111-5500-AR-PT uses a staggered polarized header and male pin configuration. This ensures that the connector is always inserted in the correct orientation without the need to align connector pins. This facilitates easy mating and improved electrical performance when connected. The male pins are plated with gold plating for improved corrosion resistance and better electrical performance. The header has a minimum length of 10.5mm, allowing the connector to be used in tight spaces.

The connector is constructed with high-quality materials to ensure a long service life. It features strain relief on the soldering points which helps protect the header-pin assembly from the stresses and strains of normal operation. The header is made of UL 94V-0 rated flame retardant materials and is designed with an extra wide solder tail to help ensure maximum contact during soldering.

The connector is RoHS compliant and UL recognized, meaning it meets the standards for environmental compliance. The use of a solderless quick-connect system also allows for fast and easy wiring.
