NOTES 1. Soldering conditions Please obey the following conditions when soldering automatically. 1) Preheating: Within 120°C 248°F and within 120 seconds 2) Soldering iron: 260°C±5°C 500°F±41°F and within 6 seconds 2. Cleaning For automatic cleaning, the boiling method is recommended. Avoid ultrasonic cleaning which subjects the relays to high frequency vibrations, which may cause the contacts to stick. It is recommended that a fluorinated hydrocarbon or other alcoholic solvents be used. 3. External magnetic field Since DY relays are highly sensitive polarized relays, their characteristics will be affected by a strong external magnetic field. Avoid using the relay under that condition. 4. Coil operating power Pure DC current should be applied to the coil. The wave form should be rectangular. If it includes ripple, the ripple factor should be less than 5%. However, check it with the actual circuit since the characteristics may be slightly different. 5. When using, please be aware that the a contact and b contact sides of 1 Form A and 1 Form B types may go on simultaneously at operate time and release time. For Cautions for Use.
