The integrated rail bus for the modular electronics
housing system
When supplying, connecting or distributing within
modular applications, the rail bus can replace the tedious
individual wiring process with a flexible and uninterrupted
system-wide solution.
The system bus is securely integrated within the 35-
mm standard mounting rail. The SMD-bus contact block
can be reflow-soldered so that it can be completely
automatically processed during the component assembly.
The resistant, gold-plated contact surfaces ensure a
permanent and reliable contact for all housing widths.
•Unlimited scalability The integrated connection
solution covers all system widths: from the 6-mm slice
to the 67-mm large-area housing.
•Easy to service during installation It's easy to
replace a module, even in existing modules groups –
without any influence on the neighbouring modules.
•Universal integration The uninterrupted system
bus issecurely integrated within the 35-mm standard
mounting rail.
•Maximum availability Five fully-galvanized and
partially gold-plated twin-arched contacts are used
to establish a permanent contact to the rail bus. THR
solder flanges ensure that the connection to the circuit
board is stable.
