IM5140 - Inductive sensor IFM - Free user manual and instructions

USER MANUAL IM5140 IFM

minFunction and features Inductive proximity switches with analogue output determine without contact the distance between object and sensing face. For the operating range (s) see the label of the unit (values are to standard mild steel targets, for other metals correction factors apply). The analogue signal can be a voltage (0…10 V) or current (4…20 mA) depending on the type of unit. Installation Screw the proximity switch to a firm base. Protect it against loosening in case of high mechanical stress. Flush mountable (fig. 1 and 2). When mounted in metal, the metal must not protrude over the sensing face.

• Open space around the sensing face when mounted in metal: fig. 3

• Minimum distances when mounting several switches of the same type: fig. 4

4Alignment of the sensing face On delivery, the sensing face is facing the front (fig. 5). The sensing face can be turned to the side (fig. 8) by loosening the fixing screw and turning the sensor block (fig. 5-8). Electrical connection The unit must be connected by an electrician. The national and international regulations for the installation of electrical equipment must be adhered to. Disconnect power. Connect the unit as indicated on the type label. The load resistance must not be higher or lower than specified in the data sheet.

90° 180°Set-up / Operation Green LED. Lights when supply voltage is applied. Yellow LED. Is lit permanently when the object is in the operating range. The LED starts to flash outside the operating range. Output characteristics (diagram) a: Operating range (s) --> LED is lit permanently b: Warning / fault range --> LED flashes

min = start point of operating range

max = end point of operating range The operation of the sensor is maintenance-free. For perfect functioning: Keep the sensing face and the open space free of metal deposits and foreign bodies.
