How to Choose 2m 3m 5m 10m Float Switch Cable Length

Cable length is a small specification that can decide whether a float switch works reliably in the field. Common SUNIOIO-style float switch options include 2m, 3m, 5m, and 10m cable lengths, and each length fits a different tank depth, mounting point, and control panel distance.

A 2m float switch cable is suitable for compact tanks and short wiring runs. A 3m cable gives more installation flexibility for small pump pits or household water tanks. A 5m cable is often preferred for deeper tanks and agricultural water-control points. A 10m cable is useful when the float must be positioned far from the junction box or control panel.

Buyers should avoid choosing the shortest cable only to reduce cost. If the cable is too tight, the float cannot swing correctly, and the pump may start or stop at the wrong water level. The cable needs enough free movement while remaining protected from abrasion, sharp edges, and heavy pulling force.
