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.


Typical Applications

1.Industrial equipment such as presses and machine tools

2.Elevators and other kinds of hoisting mechanisms, conveyor equipment.
