The new RAFIX 22FS control component range
can be combined on a common printed
circuit board together with short-travel
keys and other components thanks to its
extremely small mounting depth of 9.2 mm.
In contrast with conventional control component
arrangements, the overall mounting depth
of the complete system is drastically reduced
by using RAFIX 22FS components.
The actuators (pushbuttons, keylock switches,
selector switches, signal indicators, emergency
stop buttons) are fastened to the front panel
with a threaded ring in a 22.3 mm panel
cut-out to IEC 947. The cast-on collar seal
made of thermoflex and an integrated special
membrane provide a water-jet proof degree
of protection IP 65 to DIN.
The contact blocks are soldered onto the PCB.
Illumination of the actuator is provided by a
3 mm LED inserted into the base of the contact
block and soldered to the PCB together with
the contact block.
The printed circuit board is fastened to the
front panel with bolts, with the contact blocks
sliding almost completely into the actuators. In
this way an extremely low profile is achieved.
Additional advantages: Individual wiring is made
unnecessary and there is no more need for a
cut-out in the PCB in the control component
areas.
