Features
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 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 complies with the EMC Directive for CE Marking requirements and the EMC Regurations for UKCA Marking requirements and obtains the UL Recognition.
(excluding EX-33(-PN) and 5 m 16.405 ft cable length type)
Moreover, PNP output type which is much in demand in Europe, is also available.
New thru-beam types now feature operation mode switch and sensitivity adjuster! [EX-33-(PN)]
Can be installed in the same way as standard fibers
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.
Single-point tightening cuts down on installation work by half
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.
Takes up very little space
Unlike conventional fibers, bending radius is not a problem, so that the sensor can be securely installed alongside conveyors.
Incorporated an inverter countermeasure circuit
The EX-30 series become significantly stronger against inverter light and other extraneous light.
No protective tube needed
The EX-30 series has high bending strength, so that the protective tube used to protect conventional fiber from breakage is not needed. This also adds up to excellent cost performance.
Waterproof IP67 (IEC)
The sensors features an IP67 rating to allow their use in process lines where water is used or splashed.
Note: If water splashes on the sensor during sensing operation,
it may sense water as an object.
Bright 2-color indicator
A bright 2-color indicator is incorporated in all types.
Incorporates a sensitivity adjuster (Excluding EX-31□)
The sensor incorporates a sensitivity adjuster. It is convenient when you need fine adjustment.
