Features 1.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. 2.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. 3.Contact arrangement of 3 Form A 1 Form B Enables various forms of control circuit. 4.High breakdown voltage High breakdown voltage 2,500 Vrms(between contact sets/ between contact and coil) 5.High sensitivity Realizes thin shape and high sensitivity(500mW nominal operating power) by utilizing high-efficiency polarized magnetic circuit with 4-gap balanced armature. Typical Applications 1.Industrial equipment such as presses and machine tools 2.Elevators and other kinds of hoisting mechanisms, conveyor equipment.
