Frequently Asked Questions - IG5716 IFM

How to install the IG5716 sensor?

The sensor can be mounted flush (Sn = Xmm f) or non-flush (Sn = Xmm nf). Observe the minimum distances between detectors (8 x Sn) and the clearance zone around the active face (see figures 1-4).

What is the detection range?

The nominal sensing range Sn is indicated on the device label. It is measured with steel 37. For other metals, the range is less than Sn.

Can I use this sensor with inductive loads?

Yes, but an RC circuit must be mounted in parallel with the inductive load (see figure 7).

How to connect the sensor electrically?

Disconnect power before connection. Connect the load before switching on. Observe the current and supply voltage values indicated on the label.

What to do if the sensor does not work?

Check the power supply, connections, and load. For 2-wire detectors, a load that is too low may cause malfunction; mount a resistor in parallel. Also check series or parallel mounting.

What is the required supply voltage?

The supply voltage must match that indicated on the label. If it is not stabilized, a capacitor must be connected (e.g., 1000 μF at 24 V and 1 A).

Can I mount several sensors side by side?

Yes, but observe the minimum distances indicated (8 x Sn) to avoid interference (see figures 3,4).

How to clean the sensor?

Disconnect the device before cleaning. Use a soft dry cloth. Do not use abrasive products or solvents.

Is the sensor suitable for detecting all metals?

It detects ferrous and non-ferrous metals, but the range is optimal for steel 37. For other metals, the effective range may be less than Sn.

What is the difference between flush and non-flush mounting?

Flush mounting (Sn = Xmm f) allows embedding the sensor in a metal hole, while non-flush mounting (Sn = Xmm nf) requires free space around the active face. The nominal sensing ranges differ according to the type.

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).

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