Limit Switches - Safety Type
Plastic Body IP65
and Metal Body IP66
Product Description
They are developed in order to be
used for following operations:
For monitoring and protection of
industrial machines, without
inertia, in which down-timeisless
than access time to the
dangerous area.
Use on slidingor pivoting protectors
(covers, cases, doors, grids,etc.).
To protect operators working on
dangerous machines, by opening
the control circuit. Withdrawal of
key by opening the mobile
protector, causes immediate
stopping of the machine drive.
Specific limit switches ideal for
monitoring and protection of light
industrial machines without
inertia, equipped with angular
movement protectors (doors,
hinges, rotative covers, grid, etc.).
Detection by the rotative axis or
by means of a lever. Opening of
the mobile protector guarantees
operatorprotectionby immediately
stopping the machine drive.
To control the access point of the
hazardous area.
