Minimum cycle time: 3 s


The electrical separator ASMEL is a separators with damping. If a workpiece carrier strikes against the stop plate of the separator, the air chamber is compressed and the compressed air
escapes through the opening gap of the adjusting screw. Thus, the workpiece carrier is gently damped to a stop. The damping is with air and can be finely adjusted via a throttle screw.
If the workpiece pallet 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 carrier is not pushing against the stop plate. The extension of the stop takes place during lowering and moving up the stop plate. The lowering and rising movement of the separator, as well as the extension of the stop plate is controlled by an internal mechanism. An integrated stepper motor performs the movements necessary for these functions.


24 Volt ± 15%, with reverse polarity protection. If the voltage is higher or lower, the Power LED starts flashing in 0.25 second intervals. No more commands are executed. If the voltage range is between 20,4 V and 27,6 V again, then the Power LED is permanently on. The separator is then ready for use again.


Residual current: 0,1 A
Peak current ASMEL-50 / Actuator: 1,2 A
Peak current Sensor: 0,3 A
The current consumption of the separator takes place via the supply voltage of the actuator-connection (pin 4) and pin 1 of the sensor connection for the voltage supply of the sensors.

The values, given in the table above for the permissible total weight of the accumulated workpiece carriers (WT) and the permissible conveying speed, apply with a belt friction of µ=0,1 between workpiece carrier and conveyor band and with the use of an ASUTEC standard stop. To select the suitable separator, we recommend the use of our online product finder.
The specified weight range is composed of the minimum workpiece carrier weight mmin and the maximum workpiece carrier weight mmax.
Minimum propulsive force: The minimum propulsive force can be calculated using the formula FRmin = m/min · g · µ.
For the ASMEL-50 -> FRmin = 0,98 N. This minimum propulsive force must not be less than this, in order to ensure that the stop can be pushed by the WT into its damped (retracted) position.
Maximum propulsive force: This maximum propulsive force may not be exceeded in order to ensure a sufficient damping effect and thus the separator has sufficient force for lowering. For the ASMEL-50 -> FRmax = 49,1 N
Adjustment of damping: The adjustment of the damping effect can be regulated within a certain range. As an experience value can be stated that when the damping is adjusted to a certain weight, other weights in a range of ± 50% can be damped properly with this setting.
For example: Damping optimally adjusted to 20 kg mass to be dampened -> Damping of masses from 10 kg to 30 kg well possible. At lower masses, the damping end position is reached late or not at all. At higher masses, the damping is not strong enough and the speed of the workpiece carrier at the damping end position is still too high and the workpiece carrier will be abruptly stopped.
