Technical content

(Excluding 5 m cable length type) PNP output type available Miniaturization by using single chip optical IC 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. Incorporates a sensitivity adjuster even in this size 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. 10.5 mm 0.413 in 8.2 mm 0.323 in 19 mm 0.748 in Long sensing range 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. BASIC PERFORMANCE Clear beam spot using red LED dot light source 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. Setting distance: 80 mm 3.150 in Setting distance: 10 mm 0.394 in ø5 mm ø0.197 in spot ø1 mm ø0.039 in spot EX-26□ EX-28□ 2 m 6.562 ft 200 mm 7.874 in 160 mm 6.299 in Thru-beam type Retroreflective type Diffuse reflective type Ultra-compact Photoelectric Sensor Amplifier Built-in EX-20 SERIES Ver.2 Miniature-sized and still mountable with M3 screws Certified (Some models only) panasonic.net/id/pidsx/global Ver.2

APPLICATIONS

Detecting presence of chip components Checking protrusion of wafer Sensing objects from an opening Waterproof IP67 (IEC) 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. ENVIRONMENTAL RESISTANCE Electric power saving* The EX-20 series achieves reductions in power consumption of up to 65 %. These sensors contribute to environmental friendliness. BASIC PERFORMANCE *Effective from production in April 2011. Incorporated an inverter countermeasure circuit* The EX-20 series become significantly stronger against inverter light and other extraneous light. Note: If water splashes on the sensor during sensing operation, it may sense water as an object. *Effective from production in April 2011. Identical size Front sensing type of thru-beam type and diffuse reflective type sensors have identical appearance. Moreover, since the mounting holes are symmetrical with respect to the beam axis center, the design becomes easy. MOUNTING Mounting section reinforced It can be tightened with M3 screws.

Stability indicator

• The stability indicator (green) lights up when the incident light intensity has sufficient margin with respect to the operation level. If the incident light intensity level is such that the stability indicator lights up, stable sensing can be done without the light received operation and the light interrupted operation being affected by a change in ambient temperature or supply voltage. M3 screws Mounting
• Mount using M3 screws. The tightening torque should be 0.5 N·m or less. Front sensing Side sensing M3 pan head screws (Note) M3 screws Note: When mounting the front sensing type sensor, use M3 pan head screws without washers, etc.
• When mounting the front sensing type from the backside, fit the mounting spacer (MS-EX20-FS) and fix with screws.

1 Fit the mounting

spacer on the sensor.

2 Align the mounting holes of

the mounting spacer and the sensor and mount with M3 screws. The tightening torque should be 0.5 N

• m or less. Mounting spacer (Optional) Sensitivity adjustment (side sensing type only) Step Sensitivity adjuster Description MAX Turn the sensitivity adjuster fully counterclockwise to the minimum sensitivity position (• mark). MAX A In the light received condition, turn the sensitivity adjuster slowly clockwise and confirm the point A where the sensor enters the “Light” state operation. MAX A B In the dark condition, turn the sensitivity adjuster further clockwise until the sensor enters the “Light” state operation and then bring it back to confirm point B where the sensor just returns to the “Dark” state operation. MAX A B Optimum position The position at the middle of points A and B is the optimum sensing position. Notes: 1) Use the attached adjusting screwdriver to turn the adjuster slowly. Turning with excessive strength will damage the adjuster. 2) In case of using EX-22□ at a sensing distance of 50 mm 1.969 in or less, take care that the sensitivity adjustment range becomes extremely narrow. Operation mode switch (EX-23□ only) Switch position Description L D Light-ON mode is obtained when the operation mode switch (located on the receiver) is turned fully clockwise (L side). L D Dark-ON mode is obtained when the operation mode switch (located on the receiver) is turned fully counterclockwise (D side). Note: Operation mode switch should be turned fully till it stops. Mounting method If the sensor does not enter the “Light” state operation even when the sensitivity adjuster is turned fully clockwise, this extreme position is point B .

Light received operation Glossy object sensing (EX-29□)
• Please take care of the following points when detecting materials having a gloss. L Make L sufficiently long Sensor 10 to 30 ° Glossy surface Sensing object Reflector Wiring
• Excess bending of the cable or stress applied to the cable may disconnect the internal lead wire. Others
• Do not use during the initial transient time (50 ms) after the power supply is switched on.
• If sensors are mounted close together and the ambient temperature is near the maximum rated value, provide for enough heat radiation / ventilation.
• If a reflective object is present in the background, the sensing of EX-28□ may be affected. When setting the sensor, make sure to confirm that the reflective object has no effect. In case the reflective object affects the sensing, take measures such as removing the reflective object or coloring it in black, etc.
• Never use this product as a sensing device for personnel protection.
• In case of using sensing devices for personnel protection, use products which meet laws and standards, such as OSHA, ANSI or IEC etc., for personnel protection applicable in each region or country.
