Further improvement in the performance of D4E type. Light, thin, short and compact model. For high durability and high seal needs.
[Features]
· Improved snap action property, high durability by changing lever ratio of spring of built-in switch board.
· Excellent in dust resistance, oil resistance by using a cover for built-in switch. Provides high durability of sealing cap of plunger.
· Connector system capable of reducing the maintenance time at the time of wiring (familiar screw tightening terminals are also available).
· Micro load type switch can be used in controlling electronic circuit by metal clad contacts.
· Mold terminal type, mold terminal with operation indicator light type are also available in the screw tightening method type.
· Approved by EN (TÜV), UL, CSA, CCC standard.
· The mounting pitch and characteristics are the same as that of the conventional D4E.
