3. High noise immunity realized by the
card separation structure between
contact and coil
4. Popular terminal pitch in AV equipment field
5. Space-saving slim type
Base area: Width 11 × Length 24 mm
Width .433 × Length .945 inch
6. Conforms to the various safety standards
UL/CSA, VDE, TÜV and SEMKO SEV
approved
1. High sensitivity: 250mW
The power-saving relay is highly sensitive
at the nominal operating power of 250
mW (530 mW power consumption on LK
relays).
2. High insulation resistance between
contact and coil
1) Creepage distance and clearances
between contact and coil: Min. 6 mm .236
inch (In compliance with IEC65)
2) Surge withstand voltage between contact and coil: 10,000 V or more
