WECO Group: Product of the month

With the 140-A-126-SMD, WECO has improved the well-known PCB connector 140-A-524-SMD in genuine SMD technology with further developments and supplements of useful features.

Just as the 140-A-524-SMD the layout-compatible 140-A-126-SMD is a surface-mountable screw terminal 1,5 mm² in elevator clamping style with a pitch of 5 mm, whose solder pins are exactly aligned parallel to the printed circuit board.

A distinguishing characteristic to the 140-A-524-SMD, however, are the soldering cylinders on either side of the housing, the so-called "floating anchors". They are movable in vertical direction and thereby they obtain 100% coplanarity between solder pins and soldering cylinders. They were transferred more to the front in comparison to the connector centre in order to keep the retaining strength, where the wires are connected. Thus, the force, acting on the solder pins, is reduced in a very important way.

The mobile flange element is smaller than the stational soldering cylinders of the predecessor model and will need less space on the printed circuit board. Because the center of the soldering cylinder is in the same place there is no change of layout necessary on the PCB and thus make this products also suitable for those customers, who already use the 140-A-524-SMD products successfully and would not abandon this advantage.

Furthermore the housing is equipped with spacers, so-called "stand offs" at the base side, which ensure a better air circulation during the Reflow soldering process and thus an optimal soldering result.

Packed in magazines or equipped with high temperature resistant Pick Discs in Tape-on-Reel, this genuine SMD terminal is suitable for the automatic assembly with Pick&Place machines.
