5. ORDERING INFORMATION

Notes 1). 2A means that relay is on the "reset" status when delivery; 2B means that relay is on the "set" status when delivery.
            2). Contact is recommended for suitable condition and specifications if water cleaning or surface process is involved in
                  assembling relay on PCB

6. OUTLINE DIMENSIONS AND WIRING DIAGRAM


 
 

  Notice
1. Relay is on the ¡°set¡± status when being released from stock, with the consideration of stock risen from transit and
Relay mounting, relay would be changed to ¡°reset¡± status, therefore, when application (connecting the power supply),
please reset the relay to ¡°set¡± or ¡°reset¡± status on request.
2. In order to maintain ¡°set¡± or ¡°reset¡± status, energized voltage to coil should reach the rated voltage, impulse width
Should be 5 times more than ¡°set¡± or ¡°reset¡± time. Do not energize voltage to ¡°set¡± coil and ¡°reset¡± coil simultaneously.
And also long energized time (more than 1 min.) should be avoided.
3. When choose the relay with PCB termination, the recommended welding temperature range and duration is 240¡É to 260¡É, 2s to 5s; Please do not use the reflow welding method, if the reflow is really required, please do the normal recommended wave soldering temperature is 250¡É within 2s; the below chart is the wave soldering temperature distribution chart we recommended for your reference.

4. Relays used for metering measuring applications are usually made with dust proof structure, while most relays could be made specially per customer¡¯s specific requirements. No longer than 6months¡¯storage time is recommended for this kind of relay, and please pay attention to the storage environment. To insure contact reliability, we will keep contact status be closed when delivery if no special required by customer.

Disclaimer

The specification is for reference only. Specifications subject to change without notice.
We could not evaluate all the performance and all the parameters for every possible application. Thus the user be in a right position to choose the suitable product for their own application. If there is any quiry, please contact HANDOUK for the technical service. However, it is the user¡¯s responsibility to determine which product should be used only.
