Frequently Asked Questions - IF5793 IFM

How to mount the IF5793 sensor?

The sensor can be mounted flush or non-flush. Check the label for the associated nominal range Sn. Respect the clearance distances around the active face (figure 2) and the minimum distances between multiple detectors (figures 3 and 4).

What is the supply voltage?

The supply voltage must match that indicated on the label. If it is not stabilized, it is recommended to add a capacitor (e.g., 1000 μF, 50 WV for 24 V and 1 A).

How to connect the sensor?

Before any connection, disconnect the installation from power. Use a suitable cable: up to 30 m with cross-section < 0.5 mm², beyond that use a shielded cable or keep it 50 cm away from parasitic sources. Connect the load before turning on power.

Can I connect a lamp directly?

No, do not connect low-resistance loads such as lamps directly to the detector. Use a relay to switch these loads (figure 6).

What to do for inductive loads?

For inductive loads (coils, motors), install an RC circuit in parallel with the load to protect the detector (figure 7).

My 2-wire sensor does not work correctly, why?

A load that is too small can cause malfunction for 2-wire detectors. Install a resistor in parallel with the load (figure 8).

Can I mount several sensors in series?

Yes, but the voltage drop of each device must be taken into account to ensure the overall operation.

Is it possible to mount 2-wire sensors in parallel?

Avoid parallel mounting of 2-wire sensors except in exceptional cases. If necessary, verify proper operation according to the diagram in figure 9.

Which metals does the sensor detect?

The sensor detects all metals. The nominal range Sn is defined with steel 37. For other metals, the range may be less than Sn.

How to maintain the IF5793 sensor?

The sensor requires no special maintenance. Clean it with a dry cloth if necessary. Avoid aggressive products.

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 30 ~m and wires greater than 0.5 ~mm^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).

7 R C DC

▶ 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).

8 R DC

- 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 24 V and 1 A for example a capacitor of 1000 μF, 50 WV → fig. 10):
