POSITION MONITOR

Measurements are performed
with up to 28,000 optical axes
(IG-028), each of which monitors
the amount of light received.

Large Distance between the Transmitter and Receiver

IG-028: Max. 1500 mm IG-010: Max. 1000 mm

L-CCD* Light-Receiving Element

The sensor recognises the position of a target
and is less sensitive to its environment, making it
possible to achieve stable target measurement.

* L-CCD : Linearised-Charge Coupled Device

IP67 Protection

The enclosure is resistant to harsh
environments and offers long-term
durability.

Display Unit Options

There are two types of display units: panel
mount and DIN-rail mount. When a display
unit is connected to a communication unit,
measurement data can be sent to external
devices such as a PLC.

Intelligent

High accuracy was achieved by using the technology
and functions developed for high-accuracy measuring
instruments.

Excellent usability makes it possible to quickly and
easily perform stable measurements without any difficult
adjustments and settings.

High stability and measurement accuracy are achieved
with the newly developed optical system

Multi-Wavelength Laser + I-DSP

With conventional lasers, the transmission spot produces a patchy pattern
(as shown in the figure to the right). This is a laser-specific interference
problem caused by the laser having a single wavelength. The IG Series
sensor overcomes this problem by using a multi-wavelength laser. Because
shadows are formed on the CCD more clearly, the sensor remains highly
stable, even with targets that are conventionally
difficult to detect (e.g. transparent objects).
With the I-DSP (a parallel computing chip)
incorporated in the receiver, the sensor can
perform data processing at high speed,
reducing noise to a minimum.

SPOT IMAGE

Single-wavelength laser
(conventional laser sensor)

A patchy pattern appears.

Multi-wavelength laser (IG)

Due to the multi-wavelength
laser us ed, the beam
patter n has a more uniform
intensity distribution.

STABLE DETECTION OF TRANSPARENT
& MESH TARGETS

The L-CCD makes it possible to detect a target based on
its position. Edge control and positioning of transparent and
mesh targets can be performed stably.

Determining the Part of a Target to be Measured

The position monitor on the IG Series sensors
makes it possible to visually check how a target is
detected. The user can prevent mounting or setting
errors by observing the red lights that indicate the
received light position and the green lights that
indicate the measurement position.

Red: Indicates
the received light
position

Green: Indicates
the measurement
position

Easier Optical Axis Alignment

The position monitor makes it easier to align the optical
axis. Easily perform optical axis alignment by adjusting
the sensor head so that all of the position monitor lights
turn red.
