Double contact

FEATURES

25.0

• High contact reliability

• 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

53.3±0.3

2.098±.012

High contact reliability is achieved through

the use of a double contact.

• Forced operation contacts

16.5±0.5

.650±.020

(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 .020inch contact gap.

• 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.

• High sensitivity

16.5±0.5

.650±.020

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/

88). Complies with SUVA European

standard.
