Water detector WWD 241 with integrated Schuko plug (230 V AC, 50 Hz)
Mini float switch with 2.5 m LIYY control cable (extendable)
Operating instructions
💧 Early warning system for water & more – the smart WWD 241
Water damage rarely goes unnoticed for long – and can quickly become expensive. With the WWD 241 Smart Water Detector, you're reliably protected: The integrated mini float switch reacts at a water level as low as approximately 4 cm. As soon as the water level is reached, a loud audible alarm sounds and the LED flashes visibly red . If the water level drops again, the signal automatically stops and the display returns to green .
What's special about the WWD 241 is that it's not only suitable for water, but also detects liquids with a density of 0.7 g/cm³ and above – including heating oil, diesel, vegetable oil, and lubricating oil . This makes it versatile in use – from heating oil tanks to drip pans.
Thanks to the Smart Life app, you also receive push notifications directly on your smartphone – even when you're on the go. This way, you're always informed and can respond immediately.

💧 Mini float switch for liquid levels from approx. 4 cm
🛢️ Suitable for water, heating oil, diesel, lubricating & vegetable oils
📏 Sensor cable 2.5 m – extendable up to 50 m
⚠️ Note on use
The WWD 241 is specifically designed for areas with liquid levels, such as tanks . Typical applications: liquid containers, drip trays, and basements with a risk of backflow or leakage .
🔧 Flexible sensor cable – even over long distances
The included cable is 2.5 m long. If necessary, the cable can be extended up to 50 m (max. cross-section 2 × 0.14 mm²).
Important:
The cable must be cut and connected with terminals
Alternatively: pre-assembled special lengths available directly from Elektrotechnik SCHABUS
The LIYY control cables are only temporarily waterproof and according to the manufacturer:
→ flame-retardant , self-extinguishing , low-adhesion
→ largely resistant to oils, greases, coolants and lubricants
Not suitable for permanent water contact or outdoor use without protection .
The cables must never be laid parallel to 230 V cables to avoid interference and safety risks .
To attach the mini float switch, we recommend ordering the mounting bracket (item no. 300787) at the same time.
Alternatively, the dirt trap (item 300320) is particularly suitable for outdoor use. It is supplied with a mounting bracket and protects the mini float switch from blockages caused by leaves, small twigs or small animals in the outdoor water:
