NOTES
1. Soldering
Perform soldering under the conditions
below.
• Within 10 s at 260°C 500°F
• Within 3 s at 350°C 662°F
2. Latching relay
In order to assure proper operating regardless of changes in the ambient usage
temperature and usage conditions, nominal operating voltage should be applied to
the coil for more than 30 ms to set/reset
the latching type relay.
For Cautions for Use, see Relay Technical Information (Page 48 to 76).
