Description
Options
Short Stroke Units can be operated as individual units for
applications requiring simple linear movement or in conjunction
with each other for more complex patterns of movement.
The following are available for increasing unit options:
Cushioning
- PNP Inductive Sensors NC
End of stroke cushioning is provided by a plastic buffer for
absorbing impacts and controlling deceleration.
- NPN Inductive Sensors NC
Detection
- Adjustable threaded stops.
End of stroke sensing is by plug in Inductive Sensors.
- Flow controllers
- Auto compensating hydraulic shock absorbers
- LED fitted magnetic sensors
- Dovetail top plate or flat plate
Short stroke units
Range
Short Stroke Unit with dovetail mounting plate
There are 2 sizes in the range: piston bore Æ 16 or 25 mm.
Short Stroke Units can easily be mounted on other products in
the 3D® range with mounting kits.
Short Stroke Unit with flat mounting plate
There are 2 sizes in the range: piston bore Æ 16 or 25 mm.
Short Stroke Units can easily be mounted on other products
in the 3DÒ range with mounting kits.
Options
Auto compensating shock absorbers
Auto compensating shock absorbers may replace standard
version plastic buffers giving better end of stroke
cushioning.
They are strongly recommended for heavy use.
Inductive Sensors
Inductive Sensors send data to each end of stroke. They are
plug in type fitted with LED, making maintenance easier. They are
fitted with screw type elbow connectors. They may be mounted
on the centre body or end plates.
Magnetic sensors
For light work and cost savings, magnetic sensors can replace
inductive sensors. They are fitted with LED or not.
Adjustable threaded stop
The adjustable threaded stop fitted on the rear end plate is
for precise stroke adjustment.
A second adjustable threaded stop may be fitted on the front
end plate for linear unit use.
Flow controllers
Flow controllers may be fitted on one side of the centre body
or the other. They provide accurate flow control.
Dovetail top plate
A top plate may be mounted on a Short Stroke Unit for
mounting interface. It may therefore be mounted in 2 ways:
- by the body (linear table operation)
- by the top plate (linear unit operation)
