FR-WKZ11

RETROREFLECTIVE WITH POLARIZING FILTERS FIBER

Unaffected by surface reflection from transparent objects

FR-WKZ11 has a built-in polarizing filters in its tip, so that it is

unaffected by surface reflection from transparent objects and specular objects directly in front of it.

Gives stable detection of transparent objects

Because it’s a retroreflective type, light passes through transparent objects twice, so differences in light amount can be easily picked up and glass substrate and transparent films can be detected with good stability.

Because stable sensing is made possible at a long range, transparent objects (glass substrates and the like) can be detected through a view port.

Compact head and long sensing range

This fiber has a compact head of W9.5H5.2D15 mm W0.374H0.205

D0.591 in. Equipped with sharp bending fibers (Allowable bending radius:

R1 mm R0.039 in) making it space efficient. It is a retroreflective type with a polarizing filters that has a long sensing range of 3,200 mm 125.984 in.

Even glass substrates can be accurately detected.

Because the reflected light from the transparent object returns oscillating in the same direction as the incident light, it does not pass through polarizing filter B.

Long sensing range

Longest in the industry

Polarizing filter B

The surface reflection light of the view port facing the fiber is not received.

Light passing through polarizing filter A is changed the direction of polarization by a reflector and polarizing filter B only lets in beam whose wavelengths run horizontally.

PRECAUTIONS FOR PROPOSER USE

This product is not a safety sensor. Its use is not intended or designed to protect life and prevent body injury or property damage from dangerous parts of machinery. It is a normal object detection sensor.

•

Keep the fiber head surface intact. If it is scratched or spoiled, the detectability will deteriorate.

If the sensing surface gets dirty, wipe dirt or stains from the sensing faces with a soft cloth. (Do not use organic solvents.)

Ensure that any strong extraneous light is not incident on the receiving face of the fiber head.

Do not apply excessive tensile force to the fiber cable. (The tensile force should be 20 N or less.)

Take care that the fiber is not directly exposed to fluorescent light from a rapid-starter lamp or a high frequency lighting device, as it may affect the sensing performance.

Avoid areas prone to vapor or dust as well as corrosive gas environments. Do not expose the sensor directly to water or chemicals.

Take care that the fiber does not come in direct contact with organic solvents, such as, thinner, etc.

Mounting

Cautions

• Use M3 or less set screws (cup point), and affix the head within 15 mm 0.591 in from the tip of the fiber head. Do not exceed a torque of 0.3 Nm when tightening.

If not using the attached mounting bracket

•

The head can be affixed even without using the set screws together.

• If using the set screws together, use M3 set screws (cup point) to affix and do not exceed a torque of 0.05 Nm when tightening.

If using the attached mounting bracket

Notes: 1)

Refer to the sensor general catalog 2003-2004, catalog of each amplifier (FX-301/311 series) or dedicated homepage for fiber sensor (http://www.fibersensor.com) for details about the applicable amplifier.

The sensing ranges are the values for red LED type amplifier (excluding FX-303). The sensing range and sensing range when detecting a glass substrate are the possible

setting range for the reflector or the reflective tape. The fiber can detect an object less than 100 mm 3.937 in away. However, if setting the fiber to detect objects passing within 0 to 100 mm 0 to 3.937 in from the fiber head, unstable detection may result.

FX-311(P) does not have a FAST mode. The sensing range when detecting a glass substrate are the values for red

LED type amplifier (excluding FX-303) at STD mode. The sensing range is specified for t0.7 mm 0.028 in glass substrate for LCD.

The minimum sensing object value is the value for red LED type under optimum conditions. The optimum condition is the condition when the sensivity is set so that the sensing output just changes to light incident operation in the object absent condition.

If using the fiber with a reflector (RF-230/220/210), changes in the ambient humidity level may lead to fluctuations in the amount of incident light. Exercise caution when using the fiber set to low differences in light amount. If using the fiber in an area prone to significant changes in ambient humidity level, we recommend the RF-13.
