Miniature-sized and still mountable with M3 screws
, Korean S Mark
UL : Recognition(Excluding 5 m cable length type)
Korea's S-mark certification : Some models only
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.
The sensor incorporates a sensitivity adjuster in spite of its miniature size. It is convenient when you need fine adjustment. Further, the receiver of the thru-beam, side sensing type sensor incorporates an operation mode switch which can change the output operation.
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.
The emission area of a dot light source is smaller than that of a conventional LED flat light source, and it is possible to design a high power, narrow beam. Since a red LED dot light source is used, the red beam spot is clear even at a far place, so that alignment and confirmation of sensing position is easy. Further, since the thru-beam type, too, incorporates a visible narrow beam, it can also reliably detect small parts, such as, chip components, lead frames, etc.
The EX-20 series achieves reductions in power consumption of up to 65 %.
The sensors features an IP67 rating to allow their use in process lines where water is used or splashed.
Rust-resistant stainless steel sensor mounting brackets are available.
Note:If water splashes on the sensor during sensing operation, it may sense water as an object.
The EX-20 series become significantly stronger against
inverter light and other extraneous light.
*Effective from production in April 2011.
Front sensing type of thru-beam type and diffuse reflective type sensors have identical appearance.
It can be tightened with M3 screws. Moreover, metal inserts have been provided in the mounting holes so that the product is not damaged even in case of excess tightening.
Universal sensor mounting bracket MS-EXL2-4 (for EX-22/23/26/28/29□) and MS-EX20-5 (for EX-23□ only) which can freely adjust the height and the angle of the sensor is available.
Mounting of the front sensing type is possible from the rear side by using the mounting spacer.
ø0.5 mm ø0.020 in round slit mask and 0.5 x 3 mm 0.020 x 0.118 in rectangular slit mask are available for both side sensing type and front sensing type sensors.
A bright 2-color indicator has been incorporated in all types. (Orange LED: Operation indicator, Green LED: Stability indicator)
Two types, side sensing type and front sensing type sensors are available. Select depending on the place of mounting.
