644970-4 is a type of rectangular connector in the Headers, Male Pins category. It is used to provide a secure connection between two circuits by using the male pins on the connector and the matching female cavity on the board or panel. This type of connector is suitable for high-density applications where the connector-mounting density is a priority.The 644970-4 connector is comprised of two injection-molded plastic cover halves containing electrical contacts that mate with corresponding electrical contacts on the male pins. The connector is then mounted onto a printed circuit board or panel, with the pins being inserted into the female cavity. The connector halves contain a set of locking clips that secure the male pins in place, which ensures a reliable connection between the two circuits. Once the pins are locked into the connector, the connection is permanent and the contacts cannot be removed without manipulating or displacing the clips.The 644970-4 connector provides a reliable connection by using advanced technology and high-quality materials to ensure consistent performance in the most demanding applications. The contacts are made from high strength material that ensures a reliable connection under high temperatures and vibration. The contacts are designed to prevent corrosion, which ensures the connectors will last for many years with minimal degradation. The connector housing is also designed to resist wear, tear, and moisture, providing maximum durability in challenging environments.The 644970-4 connector is compliant with a range of industry standards, offering customers a reliable and cost-effective solution. The connector is rated for use in temperatures ranging from -55 to +125 degrees Celsius, and is suitable for use in a variety of applications. Additionally, the connector has been designed to comply with UL1977, CSA 22.2 No. 209-92, IEC 61984 standards, providing assurance of quality and reliability.In conclusion, the 644970-4 connector is a reliable, cost-effective solution for high-density applications. The connectors use advanced technology and high-quality materials to provide a secure connection between two circuits. The connector is rated for use in a range of environments and is compliant with UL1977, CSA 22.2 No. 209-92, and IEC 61984 standards.
