  • Page 8 Model No. CX-411□ Approx. 590mm or more CX-412□ Approx. 1,580mm or more CX-413□ Approx. 4.35m or more ● Since interference function is incorporated in retroreflective type CX-49□ / CX-48□, dif- fuse reflective type CX-42□, convergent reflective type CX-46□-C05 and adjustable range reflective type CX-44□, the 2 sensor heads can be mounted adjacently.

  • Page 9: 3-3 Mounting When Detecting Materials Having A Gloss

    3-3 Mounting when detecting materials having a gloss (Retroreflective type CX-493□ / CX-48□) ● Please take care of the following points when detecting materials having a gloss with ret- roreflective type CX-493□ or retroreflective type for transparent object sensing CX-48□. 1.

  • Page 10: Mounting Of Retroreflective Type For Transparent Objects

    3-4 Mounting of retroreflective type for transparent objects CX-48□ ● Optimum sensing is possible when the position of the transparent sensing object is set at the center of the sensor and the reflector. If the sensing position is set near the CX-48□ or the reflector, the sensing may be unstable.

  • Page 17: Bgs / Fgs Function (Adjustable Range Reflective Type

    5-3 BGS / FGS function (Adjustable range reflective type CX-44□) ● CX-44□ incorporates BGS / FGS function. Select either BGS or FGS function depending on the positions of the background and sensing object. BGS / FGS function can be selected by wiring of the sensing mode se- lection input (pink / 2), as shown in the figure below.
  • Page 18 <FGS (Foreground suppression) function> ● This is useful if the object and background are close together, or if the object being sensed is glossy. Sensing object Back ground ● The sensor Judges that an object is present when no light is received at position B of the light receiving element (2-segment element).

  • Page 19: Distance Adjustment (Adjustable Range Reflective Type

    5-4 Distance adjustment (Adjustable range reflective type CX-44□) ● Be sure to conduct the distance adjustment before using CX-44□. ● Since the distance adjuster of this sensor is a 5-turn adjuster, when the point A and B is adjusted as explained in the table below, there may be more than 1 turn between the point A and B.
  • Page 20 ● In case FGS function is used. Step 1. Turn the distance adjuster fully clockwise to the maxi- mum sensing range position. (approx. 50mm for CX-441□ Distance and CX-443□, approx. 100mm for CX-444□, and approx. adjuster 300mm for CX-442□). 2. Place an object at the required distance from the sensor, turn the distance adjuster gradually counterclockwise, and find out point A where the sensor changes to the stable dark condition.
