WECO Group: Product of the month

With two new pin strips WECO extends its product range of connectors suitable for the reflow soldering processes in true SMD technology with 5.0 mm pitch.

In contrary to the well-known pin strips 971-SLK and 971-SLR-THR, for which drillings in the PCB are necessary, the SMD types of WECO base on true surface assembly. Soldering expanses at the end of the pins guarantee optimal detention characteristics on the printed circuit board.

The pin strips of the series 971-SLR-SMD are available with two different pin diameters. The choice of the respective pin diameter depends on the numbers of poles of the used counterpart (plug connectors). So the pin strip 971-SLR-SMD-1,3 with the pin diameter of 1.3 mm is for example rather suitable for the small numbers of poles of the plug connector series 950-FL, 950-TFL, 950-NAF, 950-RFL and 950-NFL as well as for the series of 115-F for all numbers of poles. The obtained plug-in and pull-out forces are comfortable.
The WECO type 971-SLR-SMD-1,1 with pin diameter 1.1 mm, however, is rather suitable for higher numbers of poles, in order to minimize the arising putting and withdrawal forces here. This is not in connection with the series of 115-F.

Just like all THR versions of WECO also the housings of the SMD series are made out of high temperature resistant plastic material and exhibit a very high CTI value.

For the automatic assembling process both pin row versions are packed Tape-on-Reel and are equipped with high temperature resistant pick caps, which can comfortably be removed after the soldering process.
