Mounting of Stroke sensor on a linear feeder
a.
Model ML series are using leaf springs made of resin reinforced plastic and the
proximity sensor does not detect them.
The stainless bar as an object sensed must be mounted on in front of a leaf spring.
The stainless bar is screwed together with the leaf springs with the leaf spring fixing
bolt on the bowl side or top.
b.
The stroke sensor must be mounted on in front of the stainless bar. The sensor support
is screwed together with the leaf springs with the leaf spring fixing bolt on the base
frame side or bottom.
The sensor must be off the bar by 1.0mm and it is called the “air gap”. The width
of the gap changes by the vibration of the drive unit and the change is detected with
the proximity sensor.
The bolt must be longer than usual by the thickness of the support and the bar.
c.
Recommended stroke sensor is “EH-305 Proximity sensor” by Keyense.
d.
Size of the stainless bar
The following figure shows model of a linear feeder and the size of the stainless bar.
