Stop module with hydraulic damping unit, suitable for various systems and applications.
The stop plate can be retracted after a few millimeter of damping stoke with a separate air connection.
The retraction speed is adjustable by a throttle screw.

The stopper is fastened with 4 x M8 screws from below.
A fastening set for mounting to the side of the section profile is available a an accessories

Self-adjusting hydraulic damping unit.
Retraction speed of the stop plate is adjustable
Damping stroke ASM-400: 16 mm

ASM-400…-09: 3,10 kg
ASM-400…-09-E: 3,25 kg
ASM-400…-09-I: 3,10 kg

In order to ensure a perfect lowering movement of the stop module, the following propulsive forces must not be exceeded:
ASM-400 – F_Rmax = 549 N

In order to ensure that the stop plate reaches the damping end position, the following minimum propulsive forces must not be less than:
ASM-400 – F_Rmin = 3,43 N
If the propulsive force is lower than 30 N, the additional air connection must be supplied with compressed air to support the retraction of the stop.

The pneumatic stop modules ASM-400 are stop modules with damping.
If a workpiece carrier hits the stopper’s stop, it is stopped in a dampened manner.
After about 3 mm of damping stroke, the stop can be retracted with pneumatic support using an additional air connection.
The retraction speed can be adjusted using a throttle screw.
If the workpiece carrier will be damped, the stop plate will be pushed in.
The stop plate will stay in this position. There are no forces that would try to move the stop plate even the workpiece pallet is not pushing against the stop plate.
The extension of the stop plate is effected by an internal valve control in the stop module, when lowering, when the stop module has reached the lower position.

EW (single-acting): The lowering of the stop module is done by pneumatic pressure.
When the stop module has reached the lowered position, then the stop-damping-piston is automatically extended.
In the unpressurized state, the stop module moves upwards into the blocking position by a spring and the next workpiece carriers can be stopped.

DW (double-acting): The lowering and raising of the stop module is done by pneumatic pressure.
When the stop module has reached the lowered position, then the stop-damping-piston is automatically extended.
In unpressurized state the stop module keeps his last reached position. The stop module has no spring. This increases the lowering force.

+5°C bis +60°C

For the EW-version there is only one air connection (P1) for lowering the stop module and for the DW-variant there is an additional air connection (P2) for raising the stop module.
With the air connection (PR), the stop can be retracted pneumatically after a few millimeters of damping stroke.
