SERIES EX-20 Ultra-compact Photoelectric Sensor Amplifier Built-in Miniature-sized and still mountable with M3 screws UL Recognition Conforming to (Excluding 5 m cable length type) EMC Directive Miniaturization by using single chip optical IC Long sensing range Clear beam spot using red LED dot light source The beam-receiving photodiode and the The EX-20 series achieves long distance The emission area of a dot light source is A/D conversion circuit have been sensing thru-beam type: 2 m 6.562 ft, retro- smaller than that of a conventional LED fabricated on a single chip optical IC (full reflective type: 200 mm 7.874 in (when using flat light source, and it is possible to custom). Hence, in spite of its miniature the attached reflector), diffuse reflective design a high power, narrow beam. Since size, it has a performance and reliability type: 160 mm 6.299 in , despite its miniature a red LED dot light source is used, the red which is equal to or better than the size. beam spot is clear even at a far place, so conventional product. Hence, it is usable even on a wide conveyor. that alignment and confirmation of sensing position is easy. Further, since the thru- 8.2 mm 10.5 mm Thru-beam type 0.323 in beam type, too, incorporates a visible 0.413 in narrow beam, it can also reliably detect 2 m 6.562 ft 19 mm small parts, such as, chip components, 0.748 in lead frames, etc. EX-28 Retroreflective type Incorporates a sensitivity adjuster even in this size The sensor incorporates a sensitivity 200 mm adjuster in spite of its miniature size. It is 7.874 in convenient when you need fine adjustment. Further, the receiver of the Setting thru-beam, side sensing type sensor Diffuse reflective type distance: incorporates an operation mode switch EX-26 80 mm which can change the output operation. 160 mm 3.150 in5 mm0.197 in 6.299 in spot Setting 1 mm0.039 in distance: spot 10 mm 0.394 in Bright 2-color indicator Waterproof Globally usable A bright 2-color indicator (orange, green The sensor can be hosed down because PNP output type, which is much in LED) has been incorporated in all types. of its IP67 construction. Further, the demand in Europe, is also available. sensor mounting bracket is also made of Of course, it conforms to the EMC stainless steel. Directive and approved UL Recognition Note: However, take care that if it is exposed to (excluding 5 m 16.404 ft cable length water splashes during operation, it may type). detect a water drop itself. 212EX-20 APPLICATIONS Detecting chip components Sensing objects from an opening Checking protrusion of wafer Two types for suitable mounting Identical size Universal sensor mounting bracket is available Two types, side sensing type and front Front sensing type of thru-beam type Universal sensor mounting bracket (for sensing type sensors are available. Select and diffuse reflective type sensors thru-beam side sensing type EX-23 depending on the place of mounting. have identical appearance. Moreover, only) which can freely adjust the height since the mounting holes are and the angle of the sensor is available. Side sensing type Front sensing type symmetrical with respect to the beam axis center, the design becomes easy. Height adjustment Height adjustment: Thru-beam type Diffuse reflective type 15 mm 0.591 in (With sensitivity adjuster) (Without sensitivity adjuster) 10 mm 10 mm 0.394 in 0.394 in Angle adjustment Mounting section reinforced Mounting spacer for front sensing type is available It can be tightened with M3 screws. Mounting of the Moreover, metal inserts have been front sensing type 360 rotation provided in the mounting holes so that the is possible from product is not damaged even in case of the rear side by excess tightening. using the mount- ing spacer.
