Description
Jola FS... floating switches with built-in weight for fixing of switching point.
Description:
These floating switches are designed for mounting from the top. They are fitted with a built-in weight for fixing the switching point at the desired height; this renders additional fastening of the switch at the height of the switching point unnecessary. This weight is dimensioned in such a way that the switch tilts around its own axis when the liquid level rises and then follows the rising liquid level. This tilting action of the float activates the switching process.
These units are not suitable for use in turbulent liquids (e.g. in stirrer tanks).
Features:
Application: light current application.
Switching voltage: 24-250 Vac/dc.
Switching capacity: max. 350 VA.
Operating principle: ball-operated microswitch, potential-free changeover contact.
Float material: PP.
Seal material: FPM; on request: EPDM.
Float protection: IP 68.
Floar max. immersion depth: 10 metres head of water at + 20°C.
Application range: in liquids with a specific gravity between 0.95 and 1.05 g/cm³.
Cable: 1 or 5 meters of PVC, other cable lengths and materials on request.
Application:
black PVC cable: water, used water and slightly aggressive liquids
Other possible cables:
• grey A05RN-F cable: water, used water and slightly aggressive liquids
• red-brown silicone cable: water and certain other liquids, with low mechanical strength
• green halogen-free PUR cable: water, used water and slightly aggressive liquids
• black CM cable: water and certain acids and lyes
Please note the following:
The floating switch FS 1/K/... or FS/S1/K/... is equipped with a gold-plated crosspoint contact.
One of the characteristic properties of gold-plated contacts is that they can reliably switch the
smallest voltages and smallest currents, even after extremely long standstill times.
These gold-plated contacts have the following unfavourable properties:
• The gold layer may become burnt off even after just one-off overload. If this happens, the contact loses its ability to reliably switch the smallest voltages and smallest currents.
• Extremely frequent switching actions can also impair or destroy the gold layer, leading to the same effects as outlined above.
If you need to choose between an FS 1/K/... or FS/S1/K/... with gold-plated contact and an FS 3/K/... or FS/S3/K/... with AgNi contact for an AC/DC 24 V application, your choice should be based on the following criteria:
• Floating switch is seldom in operation but should continue to work reliably even after years:
FS 1/K/... or FS/S1/K/... .
• Floating switch is frequently in operation, is permanently in action: FS 3/K/... or FS/S3/K/... .
