Bamo MNR 7-I Magnetic Level Controllers in Stainless SteelIndonesia Industrial Parts

Bamo MNR 7-I Magnetic Level Controllers in Stainless Steel are actuated when the magnetic float passes in front of; Detection of up to 4 thresholds. The contacts are changeover and bistable: status reverses only when the float passes again in front of. Terminals are in an aluminum housing, IP 65 (cable gland M20 x1.5); Wiring diagram is shown on the board inside.

A nut limits the float movement at the stem end: by unscrewing the nut, the float is easily removed. Tip: The 2 “connection model with Ø 52 mm float and the DN 100 flange option, allow direct installation without removing the float.
