Disposal 

Our electromagnetic brake components must be 
disposed of separately as they consist of different 
materials. Please also observe the relevant authority 
regulations. Code numbers may vary according to the 
disassembling process (metal, plastic and cables). 
 

Electronic components

 

(Rectifier / Switch): 

Products which have not been disassembled can be 
disposed of under Code No. 160214 (mixed materials) or 
components under Code No. 160216, or can be disposed 
of by a certified disposal firm. 

Brake bodies made of steel with coil/cable and all 
other steel components:

 

 

Steel scrap  

(Code No. 160117) 

Brake rotor (steel or aluminum pads with friction 
linings):

 

 

Brake linings  

(Code No. 160112) 

 

Guidelines on the WEEE Directive 2012/19/EU  

Avoidance of waste from electrical and electronic devices 
and the reduction of such waste through recycling.

 

 
Our electromagnetic products (brakes, clutches) as well 
as the components required to control them (rectifiers) 
are frequently used in electrical and electronic devices 
within the appropriate area of application of WEEE, 
independent of the applicable product categories. 
The stated products do not fall within the area of 
application of this Directive. They have been classified as 

electromagnetic / electronic components 

(VDE 0580) or 

as electronic equipment (DIN EN 50178), and have been 
determined for installation in devices for "use in 
accordance with the intended purpose". Only products 
which are to be viewed as devices in terms of the 
Directive and not as parts or components are subject to 
registration obligations.
