  • Page 1 Installation Instructions Inductive sensor DC / unipolar...
  • Page 2 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)

  • Page 3: Electrical Connection

    Sn = x mm f Sn = x mm nf 2 x D Electrical connection ► Disconnect power before connecting the proximity switch; connection: → fig. 5). • For cables longer than 30 m and wires greater than 0.5 mm² 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.
  • Page 4 ► 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.
  • Page 5 ► 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):...
