Rectangular Connectors - Headers, Male Pins, are typically used in many different applications. 104894-3 specifically is widely used due to the design, materials, and construction that make it a reliable connector in many situations. By understanding how the 104894-3 works and what fields and environments it can be used in, you can ensure that your own application will be successful.

Physical Characteristics

104894-3 is an eight-position, two-row rectangular, surface-mount connector. In total, the connector has sixteen contacts made of brass, which is gold plated for high-frequency applications. The housing material is SMC, which is a high-performance plastic that is low weight and also UL recognized. The contacts are held in place by two integral hinges, and the entire connector measures just 4.90 x 19.05 x 13.97 mm, so it is considered one of the smallest connectors available. The mated connectors also have two floating points that ensure full contact when joined.

Operating Environmental Considerations

The operating temperature range for the 104894-3 connector is -55°C to +105°C, and it has a current rating of up to 3A. Other environmental considerations to be aware of include max shock ratings of 10g and max vibration ratings of 5g. This makes the connector suitable for most standard applications, and able to withstand normal day-to-day use.

Applications and Suitability

104894-3 connectors are used in a variety of applications, including industrial, automotive, and aviation electronics. This connector is well-suited for applications that need a very small, lightweight, and reliable connector. It is especially well-suited for telecom applications, due to the gold plating and the wide range of operating temperatures. The ability of the connector to handle up to 3A of current also makes it a good choice for applications where higher power is needed.

Working Principle

The working principle of the 104894-3 connector is simple in that it uses soldered contacts to join two mating connectors. The contacts are inserted into the connector from the rear, and then soldered into place on the mating connector. This ensures a tight connection with no air or other particles getting in between the connectors. The two floating points mentioned earlier also help provide additional reliability by ensuring that contact is established between the two mating connectors.

Conclusion

The 104894-3 connector is a reliable connector for many applications due to its size, weight, and operational capabilities. It is suitable for use in electronic applications such as industrial, automotive, and aviation, and is well-suited for telecom applications due to its gold plating and wide operating temperature range. Its working principle is quite simple, as it uses soldered contacts to join two mating connectors.
