Frequently Asked Questions - II5696 IFM

What is the detection range of the II5696 sensor?

The nominal sensing range (Sn) is indicated on the sensor label. It depends on the mounting type (flush or non-flush). Typically, it is 4 mm for flush mounting and 8 mm for non-flush.

How to choose between flush and non-flush mounting?

Flush mounting allows embedding the sensor in metal without loss of range. Non-flush mounting requires clearance around the active face. Refer to figures 1 and 2 of the manual for clearance zones.

What materials does the sensor detect?

The sensor detects all metals (steel, aluminum, copper, etc.). The range is maximum for steel (100% of Sn) and reduced for other metals (e.g., aluminum about 40% of Sn).

How to electrically connect the sensor?

De-energize the installation. Connect the wires L+ (brown), L- (blue) and output (black) according to the wiring diagram in the manual. If the cable length exceeds 30 m or the cross-section is >0.5 mm², use a shielded cable and keep it away from interference sources.

What to do if the sensor does not switch correctly?

Check the supply voltage, connection, and load. For 2-wire sensors, a load that is too low can cause faults; add a resistor in parallel. Capacitive loads may exceed the output current at switch-on.

Can several sensors be connected in series?

Yes, but take into account the voltage drop of each device. The power supply must provide sufficient voltage for all sensors.

Can several sensors be connected in parallel?

Parallel connection is not recommended for 2-wire sensors. Use it only in exceptional cases and verify correct operation.

How to clean and maintain the sensor?

Clean the active face with a dry, non-abrasive cloth. Do not use chemicals. Regularly check the condition of the cable and housing.

What is the service life of the sensor?

IFM inductive sensors have a long service life, typically several million switching cycles. No wearing parts are present.

Function and features

This sensor detects metals without contact and indicates their presence by providing a switched signal. Nominal sensing range (Sn) see type label; (value based on standard measurement with mild steel; a shorter sensing range for other metals).

Installation

• Flush or non-flush installation (see type label: Sn = Xmm f or Xmm nf) ( fig. 1)
• Open space around the sensing face when mounted in metal ( fig. 2).
• Minimum distance when several sensors of the same type are mounted ( fig. 3, 4).

Electrical connection

Disconnect power before connecting the proximity switch; connection: fig. 5).

• For cables longer than 30m and wires greater than 0.5mm^2 the cable should be laid separately from sources of interference (at a distance of about 50~cm ) or a screened cable should be used.
• Connect the load before applying the operating voltage.
• Observe the values for current rating and minimum load current.

• If capacitive loads are used, ensure that the peak current rating is not exceeded.

• Do not connect loads of low resistance (e.g. lamps) directly to the sensor. Switch these loads via a relay ( fig. 6):

For inductive loads a RC circuit should be connected in parallel to the load ( fig. 7).

A load which is too low for 2-wire sensors may lead to malfunction. In such a case a resistor should be connected in parallel to the load ( fig.8).

• For series connection consider the voltage drop of each unit.

As a rule avoid connecting 2-wire units in parallel (only in exceptional cases, check the safe function, fig. 9):

The supply voltage must correspond to the values indicated on the label. If it is not stabilised, a capacitor should be connected (at 24V and 1 A for example a capacitor of 1000~ F , 50WV fig. 10):
