All you need to do is to make a ø4 mm ø0.157 in hole where you would like to stop or check the object (ø6 mm ø0.236 in hole for reflective type).
Furthermore, the center of the sensing axis is the same as the center of the mounting hole, which makes it much easier to set the sensing position.

New design solves all weak points of fiber sensors

The EX-30 series solves all of the difficulties associated with fiber sensors, such as:
– Difficulty finding a suitable place for the amplifier
– Fragility of the fiber
– Extra space needed because of difficulty in bending the fiber
– The nuisance of having to use a protective tube to prevent fiber breakage

Electric power saving^*

The EX-30 series achieves reductions in power consumption of up to 65 %. These sensors contribute to environmental friendliness.

Long sensing range

The EX-30 series achieves long distance sensing.
[thru-beam type: 500 mm 19.685 in (EX-33(-PN): 800 mm 31.496 in), reflective type: 50 mm 1.969 in.]

High response speed of 0.5 ms

The same high response speed of 0.5 ms as fiber sensor amplifiers is provided, making these sensors ideal for sensing small objects, counting objects that are moving quickly and positioning items such as circuit boards.

Globally usable

It conforms to the EMC Directive and obtains the UL Recognition. (excluding 5 m <span class=”inch”>16.405 ft</span> cable length type) Moreover, PNP output type which is much in demand in Europe, is also available.
