2 Method of operation and use
The intermediate position module belongs to
the intermediate position set of pneumatic
slide unit type SLG−... . This also consists of:
cushioning support type SLG−D−...,
fastening rail type SLG−S−... and
intermediate position module type
SLG−Z−... .
The stop lever
2
of the intermediate position
module swivels in and out when the pneu
matic connections are pressurized. When it
swivels out, the slide of a linear drive (e.g.
slide unit SLG−...) knocks against the stop on
the stop lever and is therefore in an intermedi
ate position.
A magnet is fastened to the internal double
piston of the intermediate position module.
The position of the piston and thereby the
position of the stop lever (swivelled in or out)
can be scanned by means of proximity
switches in the groove
3
of the intermediate
position module.
The intermediate position module has been
designed for cushioning mass forces in a posi
tion between the end positions of linear
drives (e.g. in conjunction with the intermedi
ate position sets with a slide unit type
SLG−...). Within the permitted loading limits,
the intermediate position module also func
tions as a stop.
