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).

	Sn = x mm f Sn = x mm nf

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):
