This miniature float switch with an 8 mm switching tube combines a compact design with rapid electrical integration. Both the housing and the float are made of PVC, making the sensor ideal for water-based applications and slightly chemically contaminated media. The proven reed technology enables reliable and durable level detection without continuous current. The electrical connection is made directly via an M12 connector, while the horizontal mounting in the M12 × 1 internal thread allows for stable and clean installation.
