Safety-door Switch

• Lineup includes three contact models

with 2NC/1NC and 3NC contact forms in

addition to the previous contact forms

1NC/1NO, and 2NC.

• M12-connector models are available,

saving on labor and simplifying replace-

ment.

• Standardized gold-clad contacts provide

high contact reliability.

• Applicable to both standard loads and

micro loads.

• Free of lead, cadmium, and hexavalent

chrome, reducing the burden on the en-

vironment.
