Mini-Schwimmerschalter SHT 5010 Kunststoff | NC/NO Öffner/Schließer

🔧 How is the mini float switch connected?

It is connected to the water detector using the included 2.5m LiYY cable - simply connect it and off you go.

↕️ Can I reverse the switching function?

Yes! Simply turn the float body 180° to switch between opener and closer functions (not necessary with changer).

There is a ring magnet in the float and a Meder reed contact cast in Wepuran® in the shaft. If the float moves up, the reed contact is closed. By turning the float over you get the reverse switching function, all you have to do is loosen the E-ring at the end of the shaft.

🌊 At what water level does the float switch?

Already from a Level of 4cm The contact is activated – ideal for early warnings.

🧰 Do I need to buy the mounting bracket separately?

Yes, for secure attachment we recommend the Mounting bracket (item no. 300787) as an accessory.

Mini float switches must always be operated vertically; a maximum deviation from the vertical axis of 30° is permitted. This deviation is reliably prevented by the mounting angle.

🔌 Can the float switch also be used for other systems?

It is specially optimized for SCHABUS water detectors, but can also be used in other systems with compatible values.

📏 Is there a float switch available with a longer cable?

Yes! We produce on request Special lengths entirely according to your specifications.

💧 Are the cables waterproof? The used LIYY cables are only waterproof for a short time and not suitable for permanent contact with water. We recommend special sensors for permanently humid or wet environments.

⚙️ Do I need to use a freewheeling diode when connecting a third-party device? Yes, absolutely! If you connect a third-party network device (e.g. an external relay or contactor) to the potential-free output, a Freewheeling diode (e.g. 1N4148) be connected in parallel to the coil. It protects the sensitive reed contacts from voltage peaks that occur when switching off.

🔧 What effect does a freewheeling diode have at the relay output? When a relay or contactor is switched off, briefly high voltage peaks (induction voltage) occur. A Freewheeling diode dissipates this and thus prevents damage to the switching contacts of the water detector - particularly important for longevity and functional reliability.

❓ Why can't LIYY cables be laid parallel to 230 V mains cables?

⚠️ Important: Laying LIYY cables and 230V power cables in parallel can result in Interference, electromagnetic influences and in the worst case to Security risks lead. Please always maintain separate cable ducts or sufficient distance.

⚠️ What do I need to consider when making the electrical connection?

IMPORTANT SAFETY NOTE: A incorrect electrical connection can use the sensitive Destroy reed contacts and thereby cause a malfunction - in the worst case, resulting in personal injury or property damage.

Therefore please note:

• Kein direkter Anschluss an induktive Lasten (z. B. Relais, Magnetventile)
• Kein direkter Anschluss an kapazitive Lasten (z. B. SPS/PLS – siehe unsere „aktiven“ Wassersensoren und Schwimmerschalter) oder lange Leitungen > 50 m
• Zulässige Schaltleistung darf nicht überschritten werden

👉 For inductive loads is protection using RC element or freewheeling diode absolutely necessary.
