FEATURES
1. High contact reliability
High contact reliability is achieved
through the use of a double contact.
2. Forced operation contacts
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 .020inch contact
gap.
3. 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.
4. Separated chamber structure
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.
5. High breakdown voltage
High breakdown voltage 2,500 Vrms
between contacts and coil.
6. 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.
7. Complies with safety standards
Standard products are UL, CSA, TÜV
and SEV certified. Conform to European
standards. TÜV certified. Complies with
SUVA European standard.
TYPICAL APPLICATIONS
1. Industrial equipment such as
presses and machine tools
2. Elevators and other kinds of
hoisting mechanisms, conveyor
equipment.

1. Coil data
2. Specifications
Notes: *1. This value can change due to the switching frequency, environmental conditions and desired reliability level, therefore it is recommended to check this with the
actual load.
*2. The upper limit of the ambient temperature is the maximum temperature that can satisfy the coil temperature rise value. Refer to Usage, transport and storage
conditions in NOTES.
