Rectangular Connectors - Headers, Receptacles, Female Sockets

Rectangular Connectors are one of the most commonly used connectors in the electronics industry for both Signal and Power applications. They are most commonly used to transfer power, data, and signals between two different boards or components. 89891-440HLF Connectors are a type of rectangular connector specially designed for use in the military and aerospace industries. This type of connector is well-suited for military and aerospace applications due to its rugged design, small size, and superior electrical properties.

Description of 89891-440HLF Connectors

89891-440HLF Connectors are a type of high reliability, highly rugged rectangular connector manufactured by Amphenol. The 89891-440HLF series are designed to meet the requirements of MIL-C-24308. The connector is configured as a Male Header Receptacle and features three pins, which are made of brass with gold plating. The connector also has a snap-on shell made of polycarbonate which provides a secure connection when mated with a compatible Female Socket. The 89891-440HLF Connector has an operating temperature range of -55°C to +105°C, making it suitable for both extreme cold and hot environments. The connectors have a mechnical life expectancy of 500 mating cycles and a maximum voltage rating of 2000 VDC, making them highly reliable and suitable for applications that require high voltage.

Applications of 89891-440HLF Connectors

89891-440HLF Connectors are designed and manufactured for use in high reliability, mission critical applications in the aerospace, defense, and medical industries. * The small size and rugged design of the connector make it ideal for use in space constrained applications that require dependable connections. In addition to aerospace and defense applications, 89891-440HLF Connectors are also used in medical equipment. The connectors can withstand high speed data transmissions often required in medical imaging and diagnostics, such as MRI and CAT scanning. The connectors are highly reliable and have an operating temperature range of -55°C to +105°C, making them suitable for applications in extreme temperatures.

Working Principle of 89891-440HLF Connectors

The 89891-440HLF Connector is designed to provide reliable connections in high reliability, mission critical applications. The connector features three gold-plated pins which mate with a compatible Female Socket. A polycarbonate shell provides a secure connection when mated and prevents dust and moisture from getting inside, which can lead to unreliable connections or even equipment damage. The connector features mechanical and electrical keying mechanisms which prevent reverse connections and maximize signal integrity. When two of the connectors are mated, the pins create an electrical connection while the polycarbonate shell compresses to provide a secure connection. This allows secure and reliable data and signal transmission while preventing dust, moisture, and other environmental contaminants from getting inside and damaging the connection. The 12-pitch design of the connector prevents reverse connections which can damage the equipment.

Conclusion

In conclusion, 89891-440HLF Connectors are a type of high reliability, highly rugged rectangular connector designed for mission critical applications in the aerospace, defense, and medical industries. The connectors feature an operating temperature range of -55°C to +105°C and a mechanical life expectancy of 500 mating cycles. The three gold-plated pins provide a reliable electrical connection, while the snap-on polycarbonate shell prevents dust and moisture from getting inside and damaging the connection. The 89891-440HLF Connectors are an ideal choice for critical applications, where reliable and secure connections are essential.
