Material

Transparent polyamide based (PA-T) technopolymer. Highly resistant to shocks, solvents, oils with additives, aliphatic and aromatic hydrocarbons, petrol, naphtha, phosphoric esters.

Avoid contact with alcohol or detergents containing alcohol.

Screws, nuts and washers

Zinc-plated steel.

Packing rings

Step-shaped for the seal on the reservoir walls and NBR synthetic rubber O-ring screw underhead.

Suggested roughness of the packing ring application surface Ra = 3 µm.

Float

Glass-fibre reinforced polyamide based (PA) technopolymer, black colour, with a built-in magnetic element to activate the electric contact when the float reaches the contact threshold indicated in the drawing (data referred to mineral oil type CB68, according to ISO 3498, temperature 23°C).

Floating is ensured by fluids with densities higher than 800 kg/m³.

Bracket with male connector

Perfectly watertight, incorporating the relay (reed) with two output conductors (NO and NC version) or three conductors (SW version).

• DIN 43650 C connector in glass-fibre reinforced polyamide based (PA) technopolymer, black colour.

• 4-pole M12x1 connector, with threading in glass-fibre reinforced polyamide based (PA) technopolymer certified self-extinguishing UL-94-V0, black colour, matte finish.

For a correct assembly see Warnings.

Female connector (DIN 43650 C)

With built-in cable gland and contact holder. Front or axial output (high or low) ensuring protection against water sprays (protection class IP 65 according to table EN 60529).

Contrast screen

White lacquered aluminium. The housing, in the appropriate external rear slot, guarantees the best protection from direct contact with fluid.

It can be taken out from the inclined side, before assembly to allow the insertion of level lines or words.

Standard executions

See configuration table.

Maximum continuous working temperature

90°C (with oil).
