FEATURES
• High contact reliability
High contact reliability is achieved through
the use of a double contact.
• Forced operation contacts
(2 Form A 2 Form B)
N.O. and N.C. side contacts are
connected through a card so that one
interacts with the other in movement. In
case of a contact welding, the other keeps
a min. 0.5mm
• Independent operation contacts
(4 Form A 4 Form B)
There are 4 points of forced operation
contacts.
Each pair of contacts is free from the main
armature and is independent from each
other. So if a N.O. pair of contacts are
welded, the other 3 N.O. contacts are not
effected (operate properly) That enables
to plan a circuit to detect welding or go
back to the beginning condition.

• Separated chamber structure (2 Form
A 2 Form B, 4 Form A 4 Form B)
N.O. and N.C. side contacts are put in
each own space surrounded with a card
and a body-separater. That prevents short
circuit between contacts, which is caused
by their springs welding or damaged.
• High breakdown voltage 2,500 Vrms
between contacts and coil
• High sensitivity
Realizes thin shape and high sensitivity
(500 mW nominal operating power) by
utilizing high-efficiency polarized
magnetic circuit with 4-gap balanced
armature.
• Complies with safety standards
Standard products are UL, CSA, TÜV and
SEV certified. Comform to European
standards. TÜV certified (945/EL, 178/

standard.
