(Pending)
Used alone as Category 1 safety components or, in conjunction with other safety
switches and our complete range of safety relays, it is possible to construct compre-
hensive protection schemes with Category 2, 3 or 4 compliance.
The preleaded versions allow rapid fit, easy cable routing and function testing which
cut costs dramatically in OEM applications. Simple upgrade guarding solution for
End User applications.
Low energy basic switches are rated as follows:
