SF3-DC24V Datasheet

POLARISED, MONOSTABLE SAFETY RELAY with (mechanical linked) forced contacts operation SF-RELAYS


• Forced operation contacts (2 Form A 
   2 Form B, 3 Form A  1 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
• 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
   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
