Introduction:1-1744426-9 are rectangular connectors - headers, male pins designed and developed by 3M for applications in the industrial, automotive, aerospace, and telecommunication industries. They are designed to provide reliable and secure connection between electronic devices and modules, whether in the same enclosure or in different ones.Features:1-1744426-9 connectors are highly flexible, provide a variety of common industry standard connector configurations, and are designed to meet tight space requirements. The contact design has a very low force of spring contact points that provide a good electrical connection. The contact forces with pin mating force are designed to ensure reliable contact mating. The connector also provides excellent EMI grounding and a secure EMC for harsh environments. The connectors are also resistant to moisture, vibration, and extreme temperatures.Typical Applications1-1744426-9 connectors are widely used in various industrial, automotive, aerospace, and telecommunication applications. Examples include enclosures, power supplies, controllers, monitors, panels, computers, instruments, and appliances. They are also used in wiring for motor control, factory automation systems, automated machine manufacturing, and medical systems.Working Principle:The 1-1744426-9 connectors are designed to provide secure connectivity between two components. The contacts on the connector have a unique geometry that allows for very low mating forces with pin mating; this ensures secure connectivity between the two components. The contact forces are adjustable and can be customized depending on the application. When a plug is inserted into the connector, the spring-loaded contact force ensures a reliable and secure connection. The contacts are also designed to reduce the risk of EMI and RFI interference. The connectors also have a low mating force which helps to reduce the force required to mate two connectors.Conclusion:1-1744426-9 are highly reliable, secure, and efficient rectangular connectors - headers, male pins that are widely used in industries such as automotive, aerospace, and telecommunication. They are designed to provide a secure connection between electronic devices and modules, while providing excellent EMI and RFI shielding. The low mating force helps to reduce the force required to mate two connectors, while the adjustable contact forces ensure a secure connection. The connectors are highly resistant to harsh environmental conditions such as moisture, vibration, and extreme temperatures.
