Description

With its compact design, the model HLS-M magnetic float

switch for horizontal installation in miniature design is

ideally suited for use in small tanks, for indicating minimum

maximum levels.

The float is attached to a supported, swivelling lever and

moves with the level of the medium being measured. By

means of a permanent magnet, when a preset switch point is

reached, a reed contact (inert gas contact) is actuated.

By using a magnet and reed contact the switching operation

is non-contact, free from wear and needs no power supply.

The contacts are potential-free.

The switching function refers to a rising liquid level Standard

use as normally open contact (can be used as normally

closed contact by a 180° rotation).

The magnetic float switch is simple to mount and mainte-

nance-free, so the costs of mounting, commissioning and

operation are low.

The following five magnetic float switches are available
