Thanks to an innovative manufacturing concept using modular tooling applied to the insulation structure, ERNI is able – just six weeks after receiving the order – to supply versions with 12 to 140 pins and heights of 1.0 mm or 2.0 mm for male connectors and 4.0 mm, 6.0 mm and 8.0 mm for female connectors.
MicroCon connectors are designed for parallel (board-to-board and mezzanine), orthogonal (90-degree), and coplanar connections to the printed circuit board. Versions with varying heights for the female and male connectors allow for different board spacings of 5 to 10 mm (up to 20 mm later) for mezzanine applications. For longer distances, IDC ribbon cable connections for AWG 34 wire are available.
The MicroCon dual-row series with a 0.8mm pitch is ideal for a wide range of demanding applications in the industrial, medical, lighting, automotive, and consumer electronics markets. It complements the existing 1.27mm pitch dual-row SMD family and the 0.8mm pitch hermaphrodite MicroStac family. Despite its compact design, it remains as robust and reliable as ever. Even the basic version features reinforced outer faces. In addition to coding, a 'blind connection' guide with an extended clamping range further enhances the connection.
In the MicroCon family, ERNI Electronics has retained two fundamental design features in the miniaturized 0.8mm pitch. One feature unique to connectors of this size is the use of double-sided spring contacts for a secure connection and a high level of reliability.
Therefore, despite their miniaturized design, MicroCon connectors offer high joint tolerance with permissible misalignment tolerances on the longitudinal and transverse axes of +/- 0.7 mm. The tolerance for angular tilt is +/- 4 degrees.
While many manufacturers join male connectors by the rough-stamped printed side, which minimizes circuit capacity and the number of connection cycles, ERNI also stamps the contacts but rotates the contact tip 90 degrees. This allows for connection on a smooth surface and ensures reliable contact as well as high current capacity.
Automatic assembly:
MicroCon connectors are designed for automatic SMT assembly. For this purpose, in addition to the SMT connection, the female connector features a robust plastic housing that can also withstand the high temperatures of lead-free reflow soldering. Furthermore, MicroCon connectors are suitable for double-sided reflow soldering. The connectors are supplied on ribbons and reels for easy automatic assembly. These robust connectors are specified for >500 connection cycles and can achieve a current capacity per contact of up to 2.3 A at 20°C. The solder terminal is tin-plated.
