Finder plavákový spínač 1 prepínač 10 A 5 m kábel (72.A1.1.000.0501)

In a basement sump or rainwater collection tank, the Finder 72.A1.1.000.0501 float switch automatically controls a pump based on liquid level. The suspended switch with a 5 m PVC cable tilts as the water rises or falls, opening or closing a 10 A changeover contact to start or stop the pump.

Key specifications

• Contact configuration: 1 changeover (SPDT)
• Rated current: 10 A at 250 V AC
• Cable length: 5 m, PVC, 3 x 1 mm²
• Housing material: polypropylene (PP)
• Protection degree: IP68
• Max fluid temperature: +50 °C
• Ambient operating temperature: -20 to +60 °C
• Max operating pressure: 2 bar
• Switching angle: ±45°
• Fluid density range: 0.95–1.1 g/cm³
• Application suitability: clean water, rainwater, slightly aggressive liquids
• Mounting type: suspended

Why choose it

The polypropylene housing and PVC cable resist corrosion, and the IP68 rating allows continuous immersion. The changeover contact provides both normally open and normally closed outputs for flexible pump control.

Ideal use cases

• Automatic pump control in sumps and drainage pits
• Level monitoring in rainwater harvesting tanks
• High-level alarm or low-level cut-off in clean water applications

Good to know

The switch operates by tilting as the liquid level changes; the ±45° switching angle defines the on/off points. It is suitable for liquids with a density between 0.95 and 1.1 g/cm³, covering most clean water and slightly aggressive fluids.
