Precautions


It is recommended to reset the relay by applying the rated pulse voltage prior to installation.

Avoid dropping the product in order to maintain the performance parameters.

Ensure that the rated voltage is reached for Set or Reset operation, and that the pulse width is 5 times the operating time.

Do not supply power to the Set and Reset coils at the same time. Do not supply power to the "Set" and "Reset" coils at the same time.


The FH35L-40 latching relay is the best choice for a lot of tough switching tasks since it works so well and is so reliable.  For additional information about the technical aspects or to make changes, please get in touch with the experts at Zhejiang Fanhar Electronics Co.
