The variation of the load direction should be less then 0.3 mm (see Fig. 2). ±0.3 2N Fig. 1 Fig. 2 • When soldering make sure to have a minimum distance of 5 mm (8.5 mm), use a soldering iron with 50 W and solder for maximum 7 (2) seconds at 340 ˚C (350 ˚C). If you plan to cut the lead wire shorter than the above minimum distance please contact us. The values in brackets are for AT-5.
