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. |
