No.3

Detection of small workpieces and workpieces passing in unfixed locations

Introducing two distinctive products from OPTEX FA's fiber unit product line.

For detection of small workpieces
with high-accuracy positioning

NF-TP01

Thru-beam type

φ0.25, Thin sleeve length: 5mm

Smallest detectable object:
φ0.02 mm gold wire

Adopting a φ0.125 mm superfine core, the NF-TP01 offers powerful detection of small objects. In addition, positional adjustment of the detection point can be easily performed when mounting thanks to the inclusion of a sleeve and the workpiece not being hidden by the tip even when approaching the workpiece for detection.

Sleeve-less type
Difficult to see small workpieces and difficult to adjust position.
Superfine sleeve type
The tip does not get in the way, making positional adjustment easy.
Why is a smaller core best for small object detection?

When a sensor with built-in amplifier has a wide effective light axis, small workpieces will not be completely blocked from the light, so the amount of received light does not change much, making it impossible to detect workpieces with slight misalignment.
With a fiber unit designed for small object detection, the effective light axis is narrow, allowing for the light axis to be almost 100% blocked by the workpiece. This means changes in the amount of received light are large, ensuring stable detection.

For lines with unfixed workpiece passage locations

NF-TS40

Thru-beam type

40 mm wide screen, Side ON

Spreading the light out in a band shape through a lens allows for near-collimated light.
Because there is little light leakage even when mounted in complex areas, stable detection is possible.
The NF-TS40 is particularly suitable for detecting subtle differences in light intensity.

Positions of passing workpieces is not constant
Screw passage counting
The NF-TS40 is ideal for screw passage counting.
Stable counts can be achieved even if the positions of passing screws are varied.
Film meander detection
The NF-TS40 can be used to detect film meandering.
Using the D2RF-TAN analog output amplifier makes it possible to output an analog value that corresponds to the meandering width, allowing for easy meandering control.

Detection of workpieces with complex shapes
Bag tip detection (3-sided seal)
Detecting the sealed portions of bags is simple with the NF-TS40.
The ability to detect with near-collimated light at 40 mm wide, detection of bags is stable even with mixed tips, heights, and shapes.
