## **The next-generation new form series A new alternative to fiber sensors**
## **Simpler design**
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 Center of ø0.236 in hole for reflective type). sensing axis Furthermore, the center of the Center of sensing axis is the same as the mounting hole center of the mounting hole, which makes it much easier to set the a 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
## **BASIC PERFORMANCE**
## **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.]

## **Globally usable**
It conforms to the EMC Directive and obtains the UL Recognition. (excluding 5 m 16.405 ft cable length type) Moreover, PNP output type which is much in demand in Europe, is also available.
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.

## ~~ee~~ **MOUNTING / SIZE**
## **Can be installed in the same way as standard fibers**
## **Single-point tightening cuts down on installation work by half**
The **EX-30** series can be screwmounted (M4 for thrubeam type, M6 for reflective type) in the same way as standard fiber sensors. This means that they can be inserted into production lines in exactly the same way as conventional high-priced fiber sensors.
Conventional photoelectric sensors required four (for thru-beam type) or two (for reflective type) mounting holes and screws to be used. However, the **EX-30** series is installed with a single screw, thus cutting down on
installation work by half.
