Miniature-sized and still mountable with M3 screws

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.

BASIC PERFORMANCE

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.

Thru-beam type

Retroreflective type

Diffuse reflective type

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.

ENVIRONMENTAL RESISTANCE

Waterproof IP67 (IEC)

The sensor can be hosed down because of its IP67 construction. Further, the sensor mounting bracket is also made of stainless steel.

Note: However, take care that if it is exposed to water splashes during operation, it may detect a water drop itself.

FUNCTIONS

Bright 2-color indicator

A bright 2-color indicator has been incorporated in all types. (Orange LED: Operation indicator, Green LED: Stability indicator)

VARIETIES

Two types for suitable mounting

Two types, side sensing type and front sensing type sensors are available. Select depending on the place of mounting.

Side sensing type Front sensing type

(With sensitivity adjuster)

(Without sensitivity adjuster)

MOUNTING

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.

Thru-beam type

Diffuse reflective type

Mounting section reinforced

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.

Side sensing type

Front sensing type

OPTIONS

Universal sensor mounting bracket is available

Universal sensor mounting bracket (for thru-beam side sensing type EX-23 only) which can freely adjust the height and the angle of the sensor is available.

Mounting spacer for front sensing type is available

Mounting of the front sensing type is possible from the rear side by using the mounting spacer.

Slit mask is available

0.5 mm 0.020 in round slit mask and 0.5×3 mm 0.020×0.118 in rectangular slit mask are available for both side sensing type and front sensing type sensors.

NOTE: Mounting bracket is not supplied with the sensor. Please select from the range of optional sensor mounting brackets (four types) or universal sensor mounting bracket (for EX-23 only). (Refer to p.273)

Notes: 1) The sensing range of the retroreflective type sensor is specified for the RF-200 reflector. Further, the sensing range is the possible setting range for the reflector. The sensor can detect an object less than 30 mm 1.181 in away. However, if the reflector is set 100 mm 3.937 in or less away, the sensing object should be opaque. 2) In case of using this product at a sensing range of 50 mm 1.969 in or less, take care that the sensitivity adjustment range becomes extremely narrow. 3) The model No. with suffix "P" shown on the label affixed to the thru-beam type sensor is the emitter, "D" shown on the label is the receiver. (e.g.) Emitter of EX-21A: EX-21P, Receiver of EX-21A: EX-21AD

ORDER GUIDE

PRECAUTIONS FOR PROPER USE

Refer to p.986\~ for general precautions.

• 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.

Mounting

- Mount using M3 screws. The tightening torque should be 0.5 N·m or less.

Front sensing Side sensing

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.

Mounting method

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.

Sensitivity adjustment (side sensing type only)

Step	Sensitivity adjuster	Description
1	x	Turn the sensitivity adjuster fully counterclockwise to the minimum sensitivity position (• mark).
2	xx	In the light received condition, turn the sensitivity adjuster slowly clockwise and confirm the point A where the sensor enters the “Light” state operation.
3	xx	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 Bwhere the sensor just returns to the “Dark” state operation. (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)
4		The position at the middle of points and Bthe 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
[WC22]	Light-ON mode is obtained when the operation mode switch (located on the receiver) is turned fully clockwise (L side).
	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.

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.

Glossy object sensing (EX-29☒)

- Please take care of the following points when detecting materials having a gloss.

① Make L, shown in the diagram, sufficiently long.
② Install at an angle of 10 to 30 degrees to the sensing object.

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.
