Mini Float Switch V2A Normally Open Contact
€50.34
The Mini Float Switch Made of V2A Stainless Steel with Reversible Switching Function (Normally Open/Normally Closed) for Demanding Environments
The Schabus SHT 5013 is a handcrafted mini float switch made entirely of V2A stainless steel (material 1.4301). The shaft is turned and milled from solid material, the float body is made of stainless steel sheet, and the reed contact is soldered and potted waterproof with Wepuran®. The switching contact activates at a liquid level of approximately 4 cm and reliably monitors levels in tanks, shafts, wells and industrial systems.
The smooth stainless steel surface is particularly easy to clean. V2A is resistant to weak acids and alkalis and offers significantly higher mechanical robustness compared to plastic versions. The SHT 5013 is therefore suitable for applications with higher requirements for hygiene, corrosion resistance and mechanical stability, for example in food processing.
In the standard installation position the float switch works as a normally open (NO) contact. By turning the float body 180° you obtain the reverse contact function (normally closed, NC); only the E-ring at the end of the shaft needs to be released. It is suitable for all liquids with a density of at least 0.7 g/cm³ and is an accessory for the Schabus water detectors SHT 5000, SHT 5001 and SHT 5002.
Important note: Incorrect electrical connection can destroy the sensitive reed contacts and lead to malfunctions with personal injury or property damage. The SHT 5013 must not be operated directly on inductive or capacitive loads (e.g. relays, solenoid valves, PLC/PLS). The permissible switching capacity must not be exceeded.
Robust Level Detection from 4 cm
The SHT 5013 combines stainless steel construction, a maintenance-free reed contact and selectable switching function in a compact device.

How the SHT 5013 Is Constructed
The SHT 5013 consists of a float body on a stainless steel shaft with thread, the reed contact potted in the shaft, and a permanently connected control cable.
Float Body
The float body is made of rustproof V2A stainless steel sheet. Inside the float is a ring magnet. As the liquid level rises, the float moves upward on the shaft (stroke 7.6 mm) and the reed contact is closed. Overall dimensions are H = 59 mm × Ø 28 mm.
Shaft with Thread, Nut, Rubber Ring and E-Ring
The shaft (Ø 8.3 mm, length 62.8 mm) is solid-turned and milled from V2A stainless steel. The connection thread (M10x1) is also made of V2A. The float switch is mounted via thread, nut and rubber ring. The E-ring at the end of the shaft keeps the float on the shaft. When it is released, the float can be turned 180° and the switching function reversed. Secure vertical mounting is possible with the matching mounting bracket (Art. No. 300787).
Reed Contact (Normally Open)
A high-quality Meder reed contact is located in the shaft, soldered to the cable and potted waterproof and vibration-resistant with Wepuran®. In the standard installation position it works as a normally open (NO) contact. Protection class is IP68.
LIYY Control Cable (2-core)
The white cable (2 × 0.14 mm² LIYY/PVC) is 2.5 m long. It is only temporarily waterproof, flame-retardant, self-extinguishing and resistant to oils, greases, coolants and lubricants.
Mounting and Connection
Read the operating instructions carefully before mounting and commissioning.
Mounting the Float Switch
- Always operate the float switch vertically; the maximum permitted deviation from the vertical axis is 30°. Only then can the float body slide freely and reliably on the shaft.
- For precise, vertical mounting on tank or shaft walls, the mounting bracket (Art. No. 300787) is suitable. It ensures reliable switching function and prevents tilting.
- Do not block the float; it must remain freely movable. In shafts and outdoor areas, the dirt trap basket (Art. No. 300320) protects against leaves, sediment and small animals.
Selecting the Switching Function
- Release the E-ring at the end of the shaft.
- Turn the float body 180°. This gives you the reverse switching function (normally open or normally closed).
- Reattach the E-ring.
Connecting the Float Switch
- Take the connection assignment from the label on the packaging and connect the float switch to the water detector SHT 5000, SHT 5001 or SHT 5002 (available separately).
- For extensions, use only thin, unshielded LIYY control cable (2 × 0.14 mm²). Total length max. 50 m per alarm line.
- Never run cables parallel to 230 V mains cables. Do not permanently expose the LIYY cable to water, as it is only temporarily waterproof.
- Do not exceed the permissible switching capacity (max. 10 W, 25 V AC / 60 V DC / 0.5 A).
Protection for inductive loads: For inductive loads, the float switch must be protected by an RC circuit (AC voltage) or a freewheeling diode (DC voltage, e.g. 1N4007). Recommended RC circuit for reed contacts (10 … 40 VA): AC 24 V, 100 Ω, 0.33 µF, type A 3/24.

Frequently Asked Questions
Can I reverse the switching function?
Yes. Turn the float body 180° to switch between normally closed and normally open function. Only the E-ring at the end of the shaft needs to be released. In the standard installation position the float switch works as a normally open (NO) contact.
How does the float switch work?
Inside the float is a ring magnet; a Meder reed contact is potted in Wepuran® in the shaft. When the float moves upward, the reed contact is closed. The switching contact closes at a liquid level of approximately 4 cm.
With which devices can I use the SHT 5013?
Connection is possible to the Schabus water detectors SHT 5000, SHT 5001 and SHT 5002 (available separately). Use only thin, unshielded LIYY cable (2 × 0.14 mm²) with a maximum cable length of 50 m.
For which media is the float switch suitable?
It is suitable for all liquids with a density of at least 0.7 g/cm³ (unpressurized). Thanks to the robust stainless steel design, it can also be used in aggressive or hygienically sensitive environments such as food processing. V2A is resistant to weak acids and alkalis. For aggressive media such as salt water or chlorine-containing pool and swimming pool water, the manufacturer recommends the V4A stainless steel version.
How is the float switch mounted?
Ideally with the matching mounting bracket (Art. No. 300787) to ensure as vertical an alignment as possible with a maximum deviation of 30°. Only then can the float body slide freely and reliably on the shaft.
How much current and power can the switch handle?
The switching capacity is max. 10 watts (limit values max. 25 V AC / 60 V DC / 0.5 A). The lower the switching power, the higher the service life: at < 5 V / < 1 mA, up to one trillion switching cycles are possible.
Is the connection cable interchangeable or extendable?
The cable is permanently potted. As standard, a 2.5 m long LIYY/PVC cable (2 × 0.14 mm²) is supplied; special lengths are available on request. The cable can be extended with LIYY control cable (Art. No. 300780) up to a maximum total length of 50 m. Our support will be happy to advise you.
Is the cable waterproof?
The LIYY cable is only temporarily waterproof, flame-retardant, self-extinguishing and chemically resistant to oils, greases, coolants and lubricants. It is not suitable for permanent water contact. The float switch itself is potted waterproof to protection class IP68.
What do I need to consider for the electrical connection?
Incorrect connection can destroy the sensitive reed contacts and lead to malfunctions. No direct connection to inductive loads (e.g. relays, solenoid valves), no direct connection to capacitive loads (e.g. PLC/PLS) or cable lengths over 50 m, and the permissible switching capacity must not be exceeded. For inductive loads, protection with an RC circuit or freewheeling diode is mandatory. If in doubt, consult a qualified electrician or our support.
Why must LIYY cables not be run parallel to 230 V mains cables?
Parallel routing can lead to interference. Therefore, never run the LIYY cables parallel to 230 V mains cables.
How do I clean the float switch?
With a soft, damp cloth, without solvent-based cleaning agents. The float switch must remain free of contamination and freely movable; it must not be blocked.
How long is the warranty?
The statutory warranty of at least 2 years applies in the EU. In addition, the manufacturer Schabus offers a 5-year guarantee that can be registered online.
