Caution
- The product images are representative only. Specifications may vary by part number, including shape and color.
Product Description
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.
