LEAK FIBER

Reliable Detection

The unique effect of capillarity enables reliable detection of small leaks and viscous liquids.

Compact, Space-saving

This slim (10mm) side-mounting sensor is especially good for use in confined spaces.

Simple to Use

•

Bracket mounted with one screw, one-touch fiber head mounting.

•

No resetting or component replacement required after leak detection.

•

The simple shape of the fiber head makes it easy to wipe off the leaked liquid.

Ideal for chemicals and volatile materials

This fiber type sensor is safer to use with volatile materials (SEMI S2 compliant). The flouride resin fiber head makes it ideal for use with chemicals.

Stable Design

•

When a leak occurs, the beam from the beam-emitting part scatters through the leaked liquid and is not transmitted to the beam-receiving part.

•

If the fiber is bent or faulty, if the cable is cut or disconnected, or if the sensor is not operating correctly, the output is the same as when the beam is not received (LEAK).

•

Human error when installing the fiber is also accounted for.

Incorporated Emitting Indicator

The fiber head is equipped with an emitting indicator so that you can easily check the sensor without having to get close to it.

When leakage occurs

The beam from the beamemitting part scatters through the leaked liquid and is not transmitted to the beam-receiving part.

When there is no leakage

The beam from the beamemitting part reflects off of the surface of the sensor and is transmitted to the beam-receiving part.

DIMENSIONS (Unit: mm)

Notes: 1) Highly viscous liquid may not be detected stably.

2) Liquid being detected should also be kept within the rated ambient temperature range.

Emitting indicator

(

"3.1 protective tube)

There is a white stripe on the beam-emitting fiber cable. When setting the

amplifier, put the fiber cable with white stripe into the beam-emitting side.

The sensor will not operate correctly if the emitter and receiver are not connected correctly.

Do not scratch and spoil the fiber head surface. If it is scratched or spoiled, the detectability will deteriorate. When conducting maintenance after operation, wipe all liquid from the fiber head and mounting bracket with a soft cloth.

Do not apply excessive tensile force to the fiber cable.

Bending radius of the fiber cable must be R4mm or more. If the bending radius is smaller than the specified value, the sensing performance may deteriorate.

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

The fiber cable can be cut for adjustment using the attached fiber cutter, however, the performance of the sensor may greatly decrease depending the condition of the cut fiber cable and the connection to the amplifier.

Shortening the fiber cable excessively may result in loss of reliable detection due to an insufficient light intensity difference. (As a reference, adjust the length of the fiber cable so that the amplifier reads 4,000, or less, when mounted using the exclusive mounting bracket and without any liquid.)

Be sure to use the exclusive mounting bracket when installing the sensor to avoid human error. Reliable detection cannot be guaranteed when this mounting bracket is not used.

Do not scratch the fiber sheath while cutting the protective tube.

Be sure to adjust the sensitivity of the amplifier after mounting the fiber head in the mounting bracket and completing layout and wiring the fiber cable in actual working conditions. Perform the same sensitivity adjustment after changes in layout or installation for maintenance, etc. Changes in layout or installation after completing sensitivity adjustment may result in the loss of reliable detection due to the change of incident light intensity.

Note that the light intensity may greatly decrease when used under high temperature and high humidity for long periods.

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.
