carried out by Bartels Mikrotechnik. Because of the mechanical fixation inside the electrical connector and due to
the use of elevated driving voltages it is ensured that the pump performance is not affected by the surface corrosion.
In a long term, we will work on improving the production process. Until then, referring to the unrestricted pump
performance we ask our customers to excuse visible defects on the electrical connector.
In general, the micropump can be driven with positive alternating voltages with maximum amplitude of 250 V
at a frequency between 0 and 300 Hz.
A rectangular signal results in best fluidic performance while a sine wave
minimizes the audible noise. The actuators must be driven with a 180° phase shift in the signal.
If a pump will be damaged while using a customer
’s controller, we do not provide any warranty.
We recommend
using our dedicated controllers.
DANGER
THE MP6-SERIES MICROPUMPS ARE OPERATED AT HIGH VOLTAGES. BEFORE
OPERATION, MAKE SURE THAT ALL SPECIFIC REGULATIONS FOR ELECTICAL SAFETY
ARE FULLFILLED.
Connecting the mp6-series to the cable
The pumps can be connected via a FCC connector. The layout of the connector and pin assignment of the pumps is
as shown below. Each piezo (P1 / P2) has a single lead for the negative (-P1/-P2) and the positive (+P1/+P2) supply
voltage.
The recommended connector is a 4-pin 1.25 mm pitch FCC connector manufactured by Molex. The straight
version part number 39 53 2045.
An alternative is the angulated version with the part number 39 53 2044.
The connector is available in different versions to fit various applications. Reference drawings and further
specifications are available under www.molex.com .
The recommended maximum wire length between controller and the pump is 1 m. The customer has to assure that
the assembly of pump, controller and electrical connection complies with the EMC regulations and electrical safety
in the specific field of application.
To connect the pumps and Molex, refer to following three figures. Orientate both components as indicated on the
first picture, the pumps facing downwards with its serial number marking (!) and the Molex connector with the four
small openings visible from above. Then insert the mp6/mp6-pp flex into the Molex connector (Step1). Close the
Molex connector to complete the interconnection between both components (Step 2).
