flex micro

With the level crossing flex micro Schweizer Electronic offers a signal technical secure and cost-efficient system. It is build based on common and reliably industrial components of the standardized and world-wide used automation system SIMATIC S7-300F. Equipped with leading LED- und treadle contact technology, flex micro fulfills VÖV functional requirements.

Application area 1

(based on VöV functional requirements)


Based on the flex platform „micro“ fulfills VöV functional requirements as well. flex micro is not an independant level crossing technology but is a minimal and on micro functional specifications based model of the flex system platform.

Application area 2

Manual level crossing with SA criterias


The „manual level crossing with SA criterias“ can be easily realized based on the flex system platform as well. Due to availability reasons the model flex micro private can be normally preferred.

Application area 3

flex micro+


flex micro+“ (plus) is a flex specific variation of flex micro. Because flex micro is build based on the flex system platform as well, the model can be easily extended. Therefore flex micro+ has from the functional point of view the same advantages than micro, but can on demand be equipped with a trainstop (control light with/without ZUB) and is therefore equal to a Lz-unit.

Application area 4

flex micro private


flex micro private“ is a variation of flex micro too and is used at level crossings with a reduced and common user group (private level crossings / farming level crossings). Therefore it is reduced to a minimal useful level crossing system even with reduced timings.
