It is based on the BERNSTEIN I88 family. Its dimensions, not including the actuating head, correspond to EN 50047. The actuating head is rotary mounted and has two actuator openings. The SKI safety switch is predestined for installation on section structures and in applications with confined installation conditions. Compared to the SKT, it offers more connection space R in setting directions 50 mm min for the wiring and variants with up to three switching contacts Actuating forces FE to FI50 are available. Other advantages of this series include: Technical data z Integrated eject function (FE): The actuator is ejected if the door is not locked securely. Electrical data Consequently, the safety contact is opened, thus preventing Rated insulation voltage U max. 250 V AC i the machine from starting up. In addition, this function makes Rated operating voltage U max. 240 V e it apparent that the door still needs to be locked.

This makes it the right choice for confined installation conditions. The SKC otherwise offers the same advantages as the SK: Industrial standard with particular emphasis on safety, personal protection, variable actuator head with two actuator openings. Cap Other decisive advantages include: R 150 mm (5.9 ) min z Different actuating forces: Actuator: Metal Corresponding to your specific application, in addition to the standard 10 N, you can also choose an actuating force of 5, 20, 30 or 50 N.
