The Aqua Scanner SHT 5020 is a highly sensitive, 2 m long leak sensor that can be extended upon request. Thanks to its conductive polymer technology, it reacts to even the smallest amounts of water along its entire length – just drops are enough to trigger an alarm.
The robust sensor cable consists of two sensor wires securely embedded in a fluoropolymer carrier rod . It is corrosion- and abrasion-resistant , completely metal-free, and can be easily wiped with a damp cloth for cleaning.
Whether under kitchen units, behind bathroom furniture, next to aquariums or in laundry rooms – the Aqua Scanner can be installed discreetly over large areas and monitors entire areas instead of just individual points.
This saves you the trouble of searching for the lowest spot where water collects – and gains valuable time to avoid expensive water damage .
Ideal for installation:
under or behind kitchen and bathroom furniture
around aquariums, tanks and water pipes
on the underside of pipes
in roof insulation, under screed or in
fire-protected cable ducts (e.g. with rock wool)
in data centers, technical rooms and
Heating, ventilation and air conditioning systems
for IoT (Internet of Things) projects and smart building technology
🔌 Connection to the following water detectors required (please order separately)
SHT 5000 or SHT 5001 from Elektrotechnik Schabus.
Cabling via thin, unshielded LiYY control cable (2 × 0.14 mm²) – max. 50 m cable length per scanner.
📏 Cable extension up to 50 meters possible
The factory-installed cable length can be extended up to 50 m . The recommended cross-section is 2 × 0.14 mm² .
⚠️ Notes on cable routing and area of application
The LIYY cables used are only temporarily waterproof and, according to the manufacturer , are flame-retardant, low-adhesion, and self-extinguishing . They are resistant to oils, greases, coolants, and lubricants , but are not suitable for permanent water contact.
⚠️ Safety note: The LIYY cables must never be laid parallel to 230 V mains cables to avoid interference and safety risks.
Circuit diagram with freewheeling diode[/caption]
When using third-party power supplies , it is necessary to connect a freewheeling diode (e.g. 1N4148) in parallel to the relay or contactor.
The function of the freewheeling diode is to suppress voltage spikes that occur when the relay is turned off. This minimizes current flow and voltage, thus protecting the sensitive reed contacts.
