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. The nominal operating voltage should be applied to the coil for more than 10 ms to set/reset the latching type relay. 2. Coil connection When connecting coils, refer to the wiring diagram to prevent mis-operation or malfunction. 3. External magnetic field Since RA 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. 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 alcoholic solvents be used. 5. Soldering Manual soldering shall be performed under following condition. Tip temperature: 280C to 300C .536F to 572F Wattage: 30 to 60W Soldering time: within 5s In case of automatic soldering, the following conditions should be observed 1) Position of measuring temperature 1.0mm .039inch B A A: Surface of PC board where relay is mounted. B: Above the PC board surface. 2) IR (infrared reflow) soldering method A: B: T5 T4 T3 T2 T1 t1 T1=150C 302F T2=160C 320F T3=183C 361F T4=245C 473F T5=270C 518F t2 t3 t4 t5 t2 - t1 = 80 to 120 s t5 - t3 = 30 to 40 s t4 = 170 to 190 s Temperature rise of relay itself may vary according to the mounting level or the heating method of reflow equipment. Therefore, please set the temperature of soldering portion of relay terminal and the top surface of the relay case not to exceed the above mentioned soldering condition. It is recommended to check the temperature rise of each portion under actual mounting condition before use. The soldering earth shall be performed by manual soldering.
