1. Soldering should be done under the
following conditions:
250°C 482°F within 10s
300°C 572°F within 5s
350°C 662°F within 3s
Soldering depth: 2/3 terminal pitch
2. External magnetic field
Since DY relays are highly sensitive
polarized relays, their characteristics will
be affected by a strong external magnetic
field. Avoid using the relay under that
condition.
3. When using, please be aware that
the A contact and B contact sides of
1 Form A and 1 Form B types may go
on simultaneously at operate time and
release time.
