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

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.
