Overview

The AXT438154 is a rectangular connector for arrays, edge type, mezzanine board to board. It is a robust armada of signal contacts designed for harsh environments, with its low profile allowing usage on small footprints and dense arrays needing a minimal number of board layers. This connector offers various customizable option configurations.

Primary Application

The AXT438154 is primarily used in board to board connections but can be used in many other applications as well. Its shape makes it a designated suitable solution for edge type applications, for instance, to incorporate board to board and mezzanine or daughterboard type connection. The AXT438154 is also commonly used in combination with press-fit designs, namely allowing easy interconnection.

Connection Specifics

The AXT438154 features a 2.00mm pitch and a single row connector with 100 pins. It provides a strong connection and high retention force between the two socketed connectors, guaranteeing secure connections even in harsh environments. The AXT438154 also makes sure the matched mating height is kept intact for low profile and reliable mating.

Connection Requirements

The AXT438154 uses a 3.60mm row-to-row distance, matching the requirements of tight-space applications. The connector also features an operating temperature range from -55°C to +125°C, providing a wide coverage with temperature-sensitive applications. The connector’s rated voltage is up to 250V, allowing it to be used under strenuous electrical system conditions.

Working Principle

The AXT438154 connector makes use of a connection system with two panels. One panel, the plug, features several metal pins coming out from its configurations, while the other panel, the receptacle, features apertures where the pins are inserted. Together they form a strong, secure, and reliable connection. The two connector halves are then connected with either mechanical solder mount, surface mount, or press fit technology.

Contact Testing

The AXT438154 is rigorously tested for the performance of its contacts, providing accurate measurements that prove the connector’s stability and reliability. The contacts are tested for continuous currents, voltage and temperatures, and impedance ratio. The electrical contact resistance is measured in a continuous cycle from 250V for 2 hours at 250°C.

Conclusion

The AXT438154 is a highly robust rectangular array and edge-type connector for board-to-board connections, capable of withstanding the harshest of environmental conditions. It is complete with customizable options and applicable with a wide range of technologies. Its reliable contact resistance, precise operation, and compact size make it an excellent choice for many applications.
