Fischer Elektronik grows mixed technology connector offering

Responding to the design challenges brought about by connectors being increasingly exposed to high levels of vibration, Fischer Elektronik has added a 2.54mm grid pattern to its portfolio of connectors.

The mixed surface-mount, through hole design combines the two technologies in one insulating body which can be processed simultaneously using the reflow soldering process. The first row, which is through hole, provides a high level of stability against vibration via the contacts angled at 90 degrees. The second, surface mount, row, makes contact with the respective conductor tracks on the surface of the PCB.

There are three plug-in dimension options for the two-row male header. The three options are SL 28 SMD THR 058, SL 28 SMD THR 083 and SL 28 SMD THR 109. They are offered in a horizontal version and available with four to 40 contacts. There is also a choice of contact surface – customers can choose tin-plated or gold-plated designs.

A copper-tin alloy (CuSn) is used as a contact material. This can transmit a nominal current of up to 3.0A per contact. The insulating body is made of a high temperature-resistant thermoplastic. This enables the connector to withstand the temporary high temperatures of up to 260 degrees C during the reflow soldering process.

This material is dimensionally stable and has good mechanical properties when using filler materials, adds Fischer.

The materials used comply with EU Directive 2015/863 / EU (RoHS) and the requirements of Regulation (EC) No. 1907/2006 (REACH).
