FEATURES
• Approved to the supplementary insu-
lation class in the EN standards
(EN41003).
The insulation distance between the con-
tact and coil meet the supplementary in-
sulation class of the EN41003 standards
as required for equipment connected to
the telephone lines in Europe.
Satisfies the following conditions:
• Clearances: 2.0 mm .079 inch or more
• Creepage distance: 2.5 mm .098 inch or
more
• 2,000 V breakdown voltage between
contact and coil.
The body block construction of the coil
that is molded by plastic offers a high
breakdown voltage of 2,000 V between
contact and coil, and 1,000 V between
open contacts.
• Outstanding surge resistance.

• High sensitivity 200 mW.
• High contact capacity: 2 A 30 V DC
(Standard type)
• Surface-mount type also available.
• M.B.B. type also available
• The use of gold-clad twin crossbar
contacts ensures high contact reliabil-
ity.
• Outstanding vibration and shock re-
sistance.

Notes:
❇
1This value can change due to the s witching frequency , en vironmental conditions,
and desired reliability lev el, therefore it is recommended to chec k this with the ac-
tual load.

2The upper limit for the ambient temperature is the maximum temperature that
can satisfy the coil temperature rise. Under the pac king condition, allowab le tem-
perature range is from –40 to +70°C –40°C to +158°F.
