Inductive Proximity Switches operate by using an L/C resonant oscillator which generates, with the aid of a
coil located in the open pot core, a high frequency alternating electromagnetic field. This field emerges from
the active face of the switch.
When an electrically conductive material
(for example a steel plate) moves into the
electromagnetic field, an induced eddy
current occurs. This eddy current extracts
energy from the L/C resonant circuit in
the switch, and produces a reduction in
the oscillation amplitude. This reduction
in the amplitude is converted by the
associated electronic circuitry into a
clear electronic signal, and changes the
state of the switch.
When the electrically conductive material is removed from the alternating field the oscillation amplitude
increases which, by way of the electronic circuitry, will restore the switch to the original unswitched state.
The Normal Operating Distance is defined as the distance between the detector and the target when the
change(switching) in the logic state of the proximity switch occurs. This distance and the tests associated
in obtaining this distance are outline in CENELEC EN 50010 standards. From this standard the target for
establishing Normal Operating Distance is an iron(Fe 37) square 1mm thick, and for cylindrical switches,
the size is as shown in Table 1. The normal sensing distance Sn and Sr, Su, Sa information see Figure A.

Correction Factor
Shielded & Nonshielded
Inductive : When using inductive proximity
switches with non-ferrous metals it is nes-
cessary to apply a correction factor to the
operating distance (sensing range) as
follows:
Shielded construction includes a metal band which
surrounds the ferrite core and coil arrangement.
This helps to direct the electro-magnetic field to
the front of the sensor.
Nonshielded sensors do not have this metal
band, therefore they can be side sensitive.
Shielded Sensor Nonshielded Sensor
Capacitive : Capacitive switches have an
adjustable detection range, and are depen-
dent upon the type of material to be sensed.

Mounting
Hysteresis
Hystersis is the travel of the target between the "switch-on" point and the "switch-off" point.
This distance is required to allow the switch to properly detect the target, and reduces the
possibillity of false trips. See following figure.

Because of possible interference of the electromagnetic fields generated by the oscillators, minimum
spacing is required between adjacent or opposing "active surface" of proximity switches.
The "active surface " may be flush with the metal in which the switch is mounted, (see
Mounting".) The "active surface" must have a free zone in which no metal is present, (see figure "Non-
shielded Mounting".) When mounting proximity switches in this manner where the "active surfaces"
are opposite each other, there must be a minimum distance between them,(see figure "Opposite
Mounting".)

It is good engineering practice to mount proximity switches horizontally or with the active
facing down. Avoid proximity switches that face up wherever possible, especially if metal filings
and chips are present.

Logic functions with DC proximity sensors:
Self-contained proximity sensors can be wired in series or parallel to perform such logic functions as AND, OR, NAND, NOR. The wiring diagrams show the connection of four sensors with NPN and PNP outputs. Take into account the accumulating voltage drop per sensor added in the series-string.

The devices operate exactly like mechanical switches, with the connected load being switched
in series. They can be used into PLC inputs like relays. Notice should be taken on the influence
of minimum load current, leakage current and voltage drop.
In the "off" condition, only the leakage current(the no load current) flows through the external
load. In the "on" condition the amplifiers' output transistor conducts.
Between the connections of the proximity switch there is now a voltage drop created by the
internal Z-diode(<6v) and this should be allowed for within the supply voltage. The voltage
applied to the external load is lower than the supply voltage by an amount equal to the voltage
drop. The output amplifier is short circuit proof and overload protected.
Series and parallel connection of 2 wire DC proximity switches is not permitted.

These proximity switches are used as pilot devices for AC-operated loads such as relays, contactors,

series with an appropriate load. They, therefore, replace mechanical limit switches without alteration
of circuitry, where operating speed or environmental conditions require the application of solid state
proximity switches.

AC ouput two wire proximity switches have output circuits with SCR.
In the N.O. operation and non-sensing mode, the SCR appears OFF, in the sensed mode the SCR is ON. Load current passes through the SCR and to form feed circuit with extend load. In N.C. operation, the operation is opposite the N.O. operation.
SCR in OFF mode, (it needs by the operation internal circuit for proximity switch). The small current passing through the load is called leakage current. When the SCR is in ON mode internal circuit of proximity switch operates) This small voltage is called dropping voltage. The max. load current is 500 mA.
Leakage voltage is below 5V(load current is over 20mA) leakage current is below 2.5mA.
AC two wire output, N.C. / N.O. operation is changeable, per the schematic below.
Feedback circuit as head is connected with terminal 3 and 4, proximity switch is in N.O. Mode.
As load is connected with terminal 1 and 2, proximity switch is in N.C. mode. As SCR is in OFF
status, the internal circuit of proximity switch the working needs the very small current which
is called leakage current.
As SCR is in the status of ON, the internal operation of proximity switch, the very small voltage
available is called dropping voltage.
The max. load current is 500 mA.
Dropping voltage below 5V(load current over 20mA), leakage current is below 2.5mA.

If continuous current flowing through the load is less than 10 mA, the proximity switch
will malfunction. Connect the bleeder
resistor parallel to the load in order
to increase the current flowing through
the load to more than 10 mA. This allows
the SCR in the circuit to operate reliably,

Nominal Operating Values
NAMUR-sensors operate with a supply voltage from 5 to 25VDC. It is possible to work directly into logic circuits such as CMOS etc.
Note: different operating values(V,Ri) will counteract a change of the switching distance. Within the admissible voltage range it is necessary to adopt the resistanceRi, as well as the current in the switching point I(Sn). The following table shows typical values:
