Soldering conditions of magnetic latching relay model 973L Automatic soldering260 ± 5 ° C 3-5 seconds (SEC) Solder resistance260 ± 5 ° C for 10 seconds and 350 ± 5 ° C for 3 seconds. After being placed in normal temperature and humidity for 2 hours, the structure and characteristics are normal Overall dimension of magnetic latching relay model 973L Remarks: the size of the lead out leg is the size before pre welding. The dimension tolerance of mounting hole is ± 0.10mm.The overall dimension of the product is not marked with dimensional tolerance. When the overall dimension is ≤ 1mm, the tolerance is ± 0.2mm; When the overall dimension is between 1~5mm, the tolerance is ± 0.3mm; When the overall dimension is >5mm, the tolerance is ± 0.4mm. Order description of magnetic latching relay model 973L 1) When it is used in a polluted environment (including H2S, SO2, NO2, and other dust pollutants), it is recommended to select plastic products and verify them in actual use; 2) After the relay is installed into the PCB board, the whole board needs to be cleaned. Contact our company in time to confirm the appropriate welding method and product specification; 3) For the application scenarios where capacitive load, lamp load and motor load lamps will produce high surge current at the moment of relay connection, it is recommended to use AgSnO2 material contacts; 4) If customers have any special requirements, they can contact our company to select the corresponding product model according to the characteristics after review
