3.1Description of the Mini Compact Ejector
3.1.1Applying Suction to the Workpiece/Part (Vacuum Generation)
The ejector is designed for handling and holding workpieces by means of a vacuum in combination with
suction systems. The vacuum is generated in a nozzle according to the venturi principle, using suction
generated by the flow of accelerated compressed air. Compressed air is channeled into the ejector and
flows through the nozzle. A vacuum is generated immediately downstream of the motive nozzle; this
causes the air to be sucked through the vacuum connection. The air and compressed air that have been
removed by the suction exit together via the silencer.
The venturi nozzle on the ejector is activated and deactivated using the suction command:
• In the NO (normally open) version, vacuum generation is deactivated when
the suction signal is received.
• In the NC (normally closed) version, vacuum generation is activated when
the suction signal is received.
When objects with airtight surfaces are picked up, the integrated non-return valve prevents the vacuum
from dropping.
3.1.2Depositing the Workpiece/Part (Blowing Off)
In blow off mode, the vacuum circuit of the ejector is supplied with compressed air. This ensures that the
vacuum drops quickly, allowing the workpiece/part to be deposited quickly.
The “Blow off” pilot valve is controlled directly. The ejector switches to blow off mode for as long as the
signal is present.
The blow off function can be triggered by the ejector in two ways:
• Externally controlled actuation of the blow off valve
• Optional: external blow off

5Blow off modes
5.1Externally Controlled Blow-Off
The “blow off” valve is controlled directly by the “blow off” command. The ejector switches to blow off
mode for as long as the “blow off” signal is present.
The “blow off” signal is given priority over the “suction” signal.
5.2Blow Off Using External Compressed Air
The ejector is also available with an additional compressed air connector to supply the blow off pulse sep-
arately (external blow off function = “EB”).
While the vacuum is interrupted, small workpieces are carefully deposited using a blow off pulse.
Through fine adjustment of the vacuum, the blow off of small workpieces is prevented.
The air supply opening for blow off is controlled separately. Therefore, it is easy to fine-tune the blow off
air using either the conventional flow rate setting or an external regulator.
The release pressure can be adapted to the workpiece.

7.1Installation Instructions
CAUTION
Improper installation or maintenance
Personal injury or damage to property
4During installation and maintenance, make sure that the product is disconnected and
depressurized and that it cannot be switched on again without authorization.
For safe installation, the following instructions must be observed:
• Use only the connectors, mounting holes and attachment materials that
have been provided.
• Mounting and removal must be performed only when the device is unpres-
surized and disconnected from the mains.
• Pneumatic and electrical line connections must be securely connected and
attached to the product.
7.2Installation
The ejector can be installed in any position.
1
When installing the ejector, make sure that the area around the silencer (1) remains free to ensure the
unimpeded discharge of the escaping air.
The ejector is usually mounted using the holes on the side. Alternatively, it can be mounted using a DIN
rail or a mounting bracket (> See ch. 13 Accessories,p. 31).

7 Installation
18 / 34 EN-US · 30.30.01.02039 · 03 · 10/22
Side mounting
4There are two 4.3mm through-holes for
mounting the ejector. Use screws at least
20mm in length. Use washers if you are using
fastening screws M4 for the mounting process.
The ejector must be attached using at least 2
screws; the maximum tightening torque is
1Nm.
For start of operations, the ejector must be connected to the controller via the connection plug with a
connection cable. The compressed air must be supplied by the higher-level machine.
The installation process is described and explained in detail below.
7.3Mounting on a DIN Rail (Optional)
The product can also be mounted on a TS 35-type DIN rail using the mounting kit.
üThe mounting kit is on-hand.
1. Attach the bracket in the correct position on
the mini compact ejector with a tightening
torque of 1Nm.

7 Installation
