Magnetic proximity switches are made of reed contacts whose thin plates, trapped in a glass bulb together with inerted gas, are easily influenced by magnetic
fields that create magnetic induction, opposite polarization. Magnetic attraction
force makes thin plates flex and touch each other causing an electrical contact.
The plate’s surface has been treated with a special material particularly suitable
for low current or high inductive circuits. Magnetic sensors compared to traditional mechanical switches have the following advantage:
- Contacts are well protected against dust, oxidization and corrosion thanks to
the hermetic glass bulb and inerted gas; contacts are activated by means of a
magnetic field rather than mechanical parts.
- Special surface treatment of contacts assures in normal electrical conditions
many of working cycles.
- Maintenance free, reduce encumbrance.
The reed magnetic switches offer many electrical and mechanical characteristics
together with various output functions.
- When in normally open (N.O.) mode the open reed contact closes as magnet
approaches. They are supplied with two wires.
- When in the normally closed position (N.C.) the Redd contact, in rest position,
opens as magnet gets closer. These models are created by using exchanging
reed contacts in which N.O. output has been excluded. They are supplied with
two wires.

Voltage (V), switching current (I) and max. power (P) mean the
max. switching istantaneous value in presence of loads. When
choosing a type of contact it is recommended that the following
formula be applied: P = V x I.
For magnetic sensors which have different technical data from
shown standard ones and for the switching of inductive or capacitive loads our technical department is always at your disposal.

The above table states 2 distance values (D/C) in mm. D indicates the sensing distance, C indicates the min.
hysteresis value, under this value the contact switches off (see example of funtionig). Data shown on the above
table have an approximate value, referred to appliances which are not ferromagnetic and with magnet for frontal working. The magnetic sensors can also work with a lateral magnet. In case of setting-up on ferrous surfaces
which scatter the magnetic flux, it is necessary to interpose suitable spacers made of non-magnetic metal.

N.B.: Upon request magnets of different sizes. Type M-300 is supplyable without
plastic housing, M-300F only in dimensions 39 x 15 x 8 mm.
