POLARISED, MONOSTABLE

SAFETY RELAY with

(mechanical linked) forced

contacts operation

SF-RELAYS

enables to plan a circuit to detect welding

or go back to the beginning condition.

• Separated chamber structure

(2 Form A 2 Form B, 3 Form A 1 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.

• Forced operation contacts (2 Form A

16.5±0.3

.650±.012

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)

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
