Are there any precautions for using this relay?

Avoid using the relay under strong magnetic fields as it may change parameters like pull-in and drop-out voltage. Do not subject the relay to strong shocks or drops to maintain performance.

What is the lead time for orders?

The average lead time is one month for both peak season and off-season.
