Area Detection Fibre Optic Sensor Heads

Stable and Accurate-- Wide Area Detection with ToughFlex Fibre Sensor Heads

Thrubeam sensor lineup

Created with emphasis on wide area detection. Rated IP67, it is sturdy and easy to use.

Created with emphasis on wide area detection. Rated IP67, it is sturdy and easy to use.

POINT
TOUGH BODY

Protected by a die-cast metal case. The internal structure is filled with epoxy resin, therefore this unit is able to withstand cracks caused by impact or breakdown caused by the infiltration of liquid into the device.

POINT
STRONG CABLE BASE

The cable base unit (50 mm), uses a stainless-steel jacket. This protects the base unit, which takes on a load when the cable is winded. It is possible to install the device in a narrow space without worry.

Stainless-steel jacket structure

POINT
EASY OPTICAL AXIS ALIGNMENT

Similarities with an array fibre

Uses bundle fibre*1. Arranges 30 core fibres with a diameter of 0.25 mm. Because the light expands in a wide field, optical axis alignment can be performed with ease.

FU-A40 parallel movement characteristics (typical example)

[MEASUREMENT CONDITIONS]
Amp: FS-N11N (FINE mode, APC-OFF)
Measures the position at which ON/OFF is possible after performing maximum sensitivity settings and with all light blocked/all light entering

POINT
SLIM BODY

Compact structure, excellent for narrow installation.
(L:120 mm x W:17 mm x T:5 mm)

POINT
COST EFFICIENT AND TIME SAVING

Eliminate multiple sensors installation for wide area detection applications.

Confirmation

It is also possible to stably detect workpieces that vary in drop position.

WIDE-RANGE FIBRE LINEUP

ARRAY SENSORS

The raw fibre wires are arranged to form light into a band. Because the aperture angle is 60°, optical axis alignment is easy. Furthermore, because it features a waterproof and dust-proof structure, it has excellent environmental resistance.

When using a reflective type to detect small objects at short distances, the received light intensity will be more than that of an area type. Can detect with greater stability when detecting workpieces with vibration.

AREA SENSORS

By housing the lens within the device, the light intensity distribution is equalised. As a result, with a thrubeam type, it is possible to detect minute changes in light intensity better than an array type.

FIBREOPTIC AMPLIFIERS FS-neo Series

FS-N15CN/N15CP

Best when used under tough conditions

The introduction of a waterproof-type fibreoptic amplifiers

IP66 compatible and has NEO series functions.

Even more stable detection is possible with the FS-neo Serie

Functions that are useful when using a wide-range fibre

Edge detection mode
Ignores mild changes in light intensity caused by dirt on the detection unit and temperature changes to detect only changes in light intensity produced by the workpiece. It is possible to reduce the frequency of periodic maintenance or readjustment, enabling long-term, stabilised detection.
