Notes: 1) Energizing coil with rated voltage is basic for normal operation of a relay. Please make sure the energized voltage to relay coil have reached the rated voltage. 2) In case 5V of transistor drive circuit, it is recommended to use 4.5V type relay, and 3V to use 2.4V type relay. 3) For monostable relays, if you need to drop down voltage and hold mode after reliably operating, make sure that the effective value of holding voltage is not less than 60% of the rated voltage. 4) Maximum voltage refers to the maximum voltage which relay coil could endure in a short period of time. 5) When user’s requirements can’t be found in the above table, special order allowed.

4. 주문 코드


Notes
: 1) R type (Tape and reel) packing is moisture-proof which meets requirement of ML-3. Please choose R type packing for SMT products. For R type, the letter “R” will only be printed on packing tag but not on relay cover. Tube packing is normally not available for SMT products unless specially requested by customer. But please note that tube packing is not moisture-proof so please bake the products before use according to description of notice 11 herewith. In addition, tube packing will be adopted when the ordering quantity of R type is equal to or less than 100pcs unless otherwise specified. 2) The customer special requirement express as special code after evaluating by HANDOUK. 3) Standard tube packing lenth is 580mm. Any special requirements needed, please contact us for more details. 4) For products that should meet the explosion-proof requirements of “IEC60079 series”, please note (EX) after the specification while placing orders. Note all products have explosion-proof certification, so please contact us if necessary, in order to select the suitable products.

Notes: 1) Temperature profile shows Printed Circuit Board surface temperature on the relay terminal portion. 2) Please check the actual sodering condition to use other method except above mentioned temperature profiles.

8. 특성 곡선

NOTES

1). this relay is highly sensitive polarized relay, if correct polarity is not applied to the coil terminals; the relay does not operate properly.

2). To avoid using relays under strong magnetic field which will change the parameters of relays such as pick-up voltage and drop out voltage.

3). Relay is on the “reset” status when being released from stock, with the consideration of shock risen from transit and relay mounting, it should be changed to the “set” status when application(connecting to power supply). Please reset the relay to “set” or “reset” status on request.

4). Energizing coil with rated voltage is basic for normal operation of a relay, please make sure the energized voltage to relay coil have reached the rated voltage. Regarding latching relay, in order to maintain the “set” or “reset” status, impilse width of the rated voltage applied to coil should be more than 5 times of “set” and “reset” time.

5). For a monosteady state relay, after the relay is reliably operated, if itneeds to be kept under pressure, make sure that the effective value of the voltage is not less than 60% of the rated voltage.

6). For 2 coil latching relay, do not energized voltage to “set” coil and “reset” coil simultaneously.

7). The relay may be damaged because of falling or when shocking conditions exceed the requirement.

8). For SMT products, validation with real application should be done before your series production. If the reflow-soldering temperature curve is out of our recommendation. Generally, two time reflow-soldering is not recommended for the relay. However, if two time reflow-soldering is required, a 60-min. interval should be guaranteed and validation should be done before production.

9). Please use wave soldering or manual soldering for straight-in relay. If you need reflow welding, please confirm the feasibility with us.

10). Contact is recommended for suitable condition and specifications if water cleaning or surface process is involved in assembling relays on PCB.

11). Regarding the plastic sealed relay, we should leave it cooling naturally below 40 after welding, then clean it and deal with coating, remarkably the temperature of solvents should also be controlled below 40. Please avoid cleaning the relay by ultrasonic, avoid using the solvents like gasoline, Freon, and so on, which would affect the configuration of relay or influence the environment.

12). Relays packaged in moisture barrier bags meet MSL-3 requirements. The relays should be stored at ambient condition of 30 and 60% RH after they are removed from their package, and should be used within 168 hours. If the relay cannot be used within 168 hours, please repack them or store them in a drying oven at 25±5, 10% RH. Otherwise, relays may be subjected to a soldering test to check their performance, or they may be used after keeping them in an oven for 72 hours at with 50℃±5, 30% RH.

13). When applied with continuous current, the heat from relay coil will age its isolation. Thus, please do not ground connected the coil to reduce electrical erosion if possible. And please provide protection circuit to avoid broken wire and losses.

14). Please make sure that there are no silicon-based substances (Such as silicon rubber, silicon oil, silicon-based coating agents, silicon fillers, etc.) around the relay, because it will generate silicon-containing volatile gas, which may cause poor contact in case of silicon-containing volatile gas sticking on contact.

15). About preferable condition of operation, storage and transportation, please refer to “Explanation to terminology and guidelines of relay”.
