Inductive Proximity Switch / Sensor

EMBEDDABLE (FLUSH MOUNTING) SENSORS (F)
The metal body covers the sensing area on all sides allows the unit to be installed in metal parts or next to other sensors without causing problems of reciprocal interference.

NOT EMBEDDABLE (NON FLUSH MOUNTING) SENSORS (N/F)
The metal body leaves uncovered part of the sensing area resulting in an increased sensing distance. During installation it is important to remember the minimum distances from metallic parts in the case of inductive units and from any type of material in the case of capacitive units. It is not possible to mount more than one sensor side by side.

NOMINAL INTERVENTION DISTANCE (Sn)
The nominal distance is defined as the switching value where variations due to Changes in temperature and voltage are taken into account.

REDUCTION FACTORS IN INDUCTIVE
If the object to be sensed is not Fe37 (inductives) the intervention distance Further more if the object to be sensed has dimension and thickness less than those indicated then the intervention distance will be further reduced.

INDUCTIVE SENSORS

Aq 37                  1 x S
Stainless steel    0.9 x Sn
Brass-bronze      0.5 x Sn
Aluminum           0.4 x Sn
Copper               0.4 x Sn

SUGGESTIONS FOR MOUNTING

• Follow the indications listed in the technical characteristics for the various Families of sensors.
• Take note of the temperature limits indicated for each family of sensors. Incorrect installation may result in a modification in the switching distance Causing a change in equipment performance.
• When using sensors in areas where chemicals are present it is advised that It may be difficult to establish their corrosiveness. Generally speaking the plastic parts have a high resistance to oil, salts, petrol and other hydrocarbons.
• Do not pull the cable with excessive force and if necessary use protective Tubing.
• Install both inductive and capacitive sensors in such a way as to avoid that Any kind of material becomes deposited on the active surface.
• When installing sensor using locknuts do not overtighten them in order to Avoid damage to the body of the sensor and the internal circuit. Particular Attention should be given to sensors with a diameter equal to or less than 12 mm. Attention should all be given to avoid the installation of a sensor into a Hole with the same diameter as this may cause irreparable damage. is recommended that further information be requested from our technical

SWITCHING DISTANCE (Sn)

• This is the switching distance measured at 20°C and nominal supply voltage, using a square piece of Fe 37 (EN50010) steel of 1 mm. thickness the side of which must be equal to or greater than the diameter of the active surface. In this condition the sensor switches in a Sn range of “10% Sn.
