RAFIX 22 FS

Cast-on

collar seal

Special sealing

Combined with short-travel keys

The actuators of the RAFIX 22FS system are suited for

integration into low-profile data entry systems. The small

mounting depth and the PCB solder terminals make it

possible to combine the contact blocks with Rafi

short-travel keys RACON 8 an 12, RF 15 and RF

19 as well as KN 19 on one and the same

printed circuit board.

Illumination

RAFIX 22 FS pushbuttons,

selector switches and emergency

stop buttons are also available

as illuminated versions. For illumi-

nation, we recommend to use the

superbright 3 mm LEDs in the colour

matching the lens. The LEDs are fitted

into the contact block and soldered

together with it. The signal indicators are

als illuminated with superbright LEDs

soldered directly onto the printed circuit board. In order

to ensure full illumination, the LED must be mounted on

a base. Bases are available as accessories.

Sealed against moisture and dirt

O-ring seal

The O-ring seals the space between the lens and the

actuator. The cast-on collar seal cannot be lost or

distorted during assembly. During assembly, the actuator

is held in the mounting hole by the cast-on seal and can

then be fixed by screwing from the rear.

The special membrane seal safely prevents moisture, oil

or dust from reaching the contact block.

In contrast with seals sliding up and down along the

shaft, the special membrane seal is arranged in a fixed

position on the housing. In this way, RAFIX 22 FS

guarentees switching raliability for the full service life

(degree of protection IP65 to DIN).
