Switching Power Diagrams
Voltage (V), switching current (I) and max. power (P) mean the max. switching instantaneous 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. |

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:

The table to above 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 functioning). Data shown on the 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.
