S20
Safety Switch for guarding the sliding door on a pick-and-place machine
The S20 is a Safety Switch without guard
interlocking, which can always be used
when the dangerous movement has
stopped before the entering person can
reach the point of operation. This is the
case, for example, with machines and systems where the operator is protected from
the point of operation with cages/grids or
sliding doors, and a process or production
interruption is essentially possible and may
be required. The S20 series Safety
Switches have a housing made of fiberglass-reinforced plastic in accordance with
protection rating IP 67. The models
equipped with various contact sets enable
integration in control circuits up to category
4 in accordance with EN ISO 13849. The
swivel deflecting head and numerous actuators enable universal use of this Safety
Switch.
