Type DM: Vertical mounting, reed switch contact, polypropylene stem with M8 thread, dia. 29x16.4 mm hollow polypropylene float, cable output , for near bottom level detection


Use: low voltage circuits

Main applications: steam generators, coffee machines, vending machines, air conditioning pumps, dehumidifiers. Large diameter float for low water level detection

Stem material: polypropylene

Float material: hollow polypropylene

Mounting: vertical, throw wall, with M8 nut and flat NBR gasket

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

Electrical rating:

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

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

Contact resistance: 150mOhms maxi ( wires not included)

Wires: AWG24 cable, UL style 2464, PVC insulated, length 100, 500, 1000 or 2000 mm

Liquid limits: to be used with liquids chemically compatible with polypropylene, dynamic viscosity higher than 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

Maximum pressure: 1 bar (15 PSI)

Options: other cable length, electrical rating 70W, 1A, 250VAC
