641938-9

Rectangular connectors are designed to provide a reliable and secure mating solution for a variety of applications from industrial to military and aerospace. Within this category, header connectors provide a more cost effective and flexible solution when it comes to efficiently connecting a range of components.

641938-9 is a type of header connector with male pins. This connector is used in a wide variety of applications, from medical to electronic. It features 3.96mm pitch, 80 contacts, double rows of pins with polarizing keys for reliable mating, and a sealed enclosure made of high temperature thermoplastic for protection against moisture, dust, and oil.

This connector is suitable for both power supplies and data transmission applications, with an operating voltage range of 0.5A to 3.5A. As for environmental conditions, the connector is designed to work in temperatures ranging from -40˚C to 125˚C, relative humidity of up to 95%, and a maximum operating pressure of 5,000 mbar.

The connector’s principle of working can be divided into three main parts:

• Primary Contact: This is the first part of the connection process and refers to the physical contact of each pin by using either a press-fit or crimp connection.

• Secondary Contact: After the pins and sockets are securely connected, the secondary contact is secured using a pivoting latch. This latch is used to ensure the two components are correctly mated by spring-loaded contacts.

• Tertiary Contact: Finally, the tertiary contact occurs with the polarized keys, which are used to ensure the connector is perfectly aligned in order that the connection works correctly.

The 641938-9 connector is a versatile and reliable solution for connecting a wide variety of components. It is cost effective and easy to install, making it a great option for various applications and industries. In addition, its operating temperature range and moisture/dust/oil resistance make it suitable for rigorous and harsh conditions.
