Type: DMF Miniature vertical level switch with waterproof connection box

Main applications: Water level control in vending machines, pumps, dehumidifiers, aquariums, swimming pool skimmers, electrochemical surface treatment tanks

Stem material: Polypropylene.

Float material: Hollow polypropylene.

Mounting: Vertical, fixing with the 2 hole bracket of the connection box.

Contact configuration: Normally closed when float is down on the stem. It opens when float goes up to connection box side. Upsetting the float changes the contact configuration into normally open.


Low voltage type: Maximum power 10 W (VA), max 0.5Amp, max voltage 110VAC.

230VAC type: Maximum power 40 W (VA), max 1Amp. Values for resistive circuit. For inductive or capacitive loads, a contact protection circuit must be used.

Contact resistance: 150 milli-Ohms maxi.

Connection box:  Black PA66 box, 61x33x30mm, IP69K, with 2.5mm² 3 way screw terminals, wire outputs by M12 cable gland.

Mounting: By bracket with 2 holes dia. 4.2 mm, 42 mm distance

Liquid limits: To be used with liquids chemically compatible with polypropylene, dynamic viscosity higher 0.5×10-4 Pa.s and lower than 10-2 Pa.s, specific gravity higher than 0.9, without magnetic particles.

Ambient temperature: -20+80°C

Options: Connector instead of cable gland, slosh shield for use in turbulent water applications; electrical rating 70W, 1A, 250VAC; level switch body in black polypropylene.
