3.5 mm 0.138 inthick
Smallest body,just 3.5 mm 0.138 in thickIt can be mounted in a very small space as its size is just W10�H14.5�D3.5 mm W0.394�H0.571�D0.138 in (thru-beam, front sensing type).
14.5 mm0.571 in
A convenient 2-color indicator has been incorporated in the miniature body.
Bright 2-color indicator
A flexible cable type with greatly improved bending durability compared to previous types is available. It is ideal for moving parts such as robot arms.
Increased bending durability EX-�-R
The sensor is suitable for detecting small and high-speed traveling objects.
High-speed response time: 0.5 ms
Thru-beam type sensor incorporated with an operation mode switch on the bifurcation is also available. It helps you to test the operability before start-up.
The EX-20 series achieves long distance sensing [thru-beam type: 2 m 6.562 ft, retroreflective type: 200 mm 7.874 in (when using the attached reflector), diffuse reflective type: 160 mm 6.299 in], despite its miniature size.Hence, it is usable even on a wide conveyor.

It can be tightenedwith M3 screws.Metal sleeve inserts have been provided in the mounting holes so that the product is not damaged even in case of excess tightening.
A red LED dot light source is used to cast a red spot beam so that the sensing position can be checked easily.
Spots can be seen clearly
The beam-receiving photodiode and the A/D conversion circuit have been fabricated on a single chip optical IC (full custom). Hence, in spite of its miniature size, it has a performance and reliability which is equal to or better than the conventional product.

All you need to do is make a "4 mm "0.157 in hole where you would like to stop or check the workpiece."6 mm "0.236 in hole for reflective type
A cabtyre cable is used, so that the sensor cable will not break like fibers.
Unbreakable
Unlike fibers, bending radius is not a problem, so that the sensor can be securely installed alongside conveyors.

The EX-30 series can be screw-mounted (M4 for thru-beam type, M6 for reflective type) in the same way as standard fibers. This means that they can be inserted into production lines in exactly the same way as conventional high-priced fiber sensors.
