Relays are packaged in magazine cases for shipment.

When some relays are taken out of the case and space is freed inside, be sure to secure the relays in the case with a stopper. If the relays are not well secured, vibration during transportation may cause problems.
 

If an individual relay falls from the work table, etc. a shock of 1000 G or more can be applied to the relay, possibly causing functional problems. Even if the shock is apparently weak, confirm that there are no functional abnormalities before using the relay.
