Important notes at the end of this document.



The leads to the contactor must be securely tightened to the terminals (check torque specification

in data sheet) otherwise current stress may generate sparks and heating. Use only suitable

screws for all mechanical connections to the contactor and verify their functionality in the

application.



After long-term operation the contactor coil resistance is increased due to the temperature rise. If

the contactor is switched on immediately afterwards, the coil characteristics may be deteriorated.



The coil contacts need to be protected from overvoltage when switching off. Therefore, a

protection device needs to be installed in parallel.



For successful pick-up, the voltage cannot be ramped up slowly. The voltage needs to be applied

instantly to at least the maximum pick-up voltage.



The contactor is not intended to be used with pulse width modulation (PWM) controllers. Please

contact TDK for details.



Simultaneously applied maximum operation parameters for e.g. coil voltage, over currents,

temperature, vibration etc. may lead to reduced lifetime. We recommend applying rated settings

to achieve optimum life performance.



For parts without plus or minus marking at the main HV contacts (e.g. no polarity of main

contacts), the service life curves are estimated based on the requirements of IEC60947-4-1;

Chapter 8.2.4 where 50% of the required operations are performed in positive direction and 50%

in negative direction.



For additional safety, the contactor must be mounted in a way that the vertical axis of the part (Z-

axis) is not in line with the main shock axis inside the application.

Still, it must be mounted either upright standing or horizontal lying on either side.

Overhead mounting must be avoided and only the original mounting holes are allowed to be used

to mount the part.



Contactors radiate magnetic and electromagnetic fields. Please ensure that other components

mounted in close proximity are not affected.



In case two contactors are mounted in close proximity, a clearance distance of 10 mm has to be

kept.



The operating life of the contactor can be affected by strong magnetic fields. Please ensure that

there are no magnetic field sources in close proximity and avoid nearby installed heat sources.



The contactor must not be operated without any load. This may increase the contact resistance.



Contactors may become hot during extended periods of current overload (burn hazard).



Contactors must be handled with care and must not be dropped.



If a current occurred that exceeded the maximum breaking current by more than 50% or triggered

a series fuse, the contactor is considered damaged and must be replaced.



The manufacturer cannot be held liable for failures caused by condensation or icing. The

customer has to apply suitable measures to avoid these circumstances.



This contactor is not waterproof.



It must be ensured that during usage, storage, or transportation direct sunlight is avoided.

The ambient temperature during usage must not exceed the value specified in this data sheet.



It is forbidden to use this contactor in atmospheres loaded with organic solvents (alcohol,

petroleum, etc.) or strong alkaline substances (ammoniac, acids in general, etc.).



It must be ensured that during installation and operation no kind of foreign matter adheres to the

main contact. Especially oils and silicones must be avoided.



It is forbidden to attach any kind of additional construction to or on the contactor.
