• An electrical overcurrent may reduce cycle life-time.
• We recommend validating the current profiles within your specific application and ambient conditions.
• Do not attempt to operate the actuator at constant voltage!

Use our ECU-S for easy evaluation of ourCA0408. With the ECU-S you can either control
the CA0408 manually with pressing a button orby interfacing the IO-Pin. We also offer anelectronic control unit for integration on yourcustom PCB. Please contact us for moreinformation.

Installation Instructions
Custom plungerCounter nut(if required)

The memetis chip actuator CA0408 provides a full through-holefor a custom plunger with M2 external threading.
A long plunger (> 20 mm) may be used to:• Stabilize the vertical plunger alignment• Fine-tune the plunger length after mounting• Monitor the plunger position using an external distance sensor(e.g. Laser, Hall-sensor, mechanical switch)

Slit for plunger fine-tuning

The memetis chip valve actuator provides a full through-hole for acustom plunger with M2 external threading. A long plunger (>20mm) may
be used to- stabilize the vertical plunger alignment- fine-tune the plunger length after mounting- monitor the plunger position using an external distance sensor (e.g.
Laser, Hall-sensor, mechanical switch)
