SF2D-DC12V中文资料Flat type safety relays (double contact) SF RELAYS Double contact type数据手册Panasonic规格书

描述 Description

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.
