Control Components

RAFIX 22 FS

The new RAFIX 22 FS 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.

The actuators and signal indicators

are fastened to the front panel with a

threaded ring in a 22.3 mm panel cut-

out to IEC 60947. 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.
