Description

The LaserSight™ 9000 is a Class 1 visible red laser sensor designed for the
of small parts in
industries. This sensor offers multiple sensing
purpose detection that can be easily set up by using the single-turn
potentiometer and the highly visible user interface.

Features

• Small spot size suitable for high precision sensing

• Class 1 visible laser beam for ease of alignment

• Precision long distance object detection in
transmitted beam sensing modes

• Selectable light operate or dark operate

• Solid-state DC output and SPDT relay output models

• IP69K rated

Interface

Using a screwdriver, open the top cover of the sensor to access the user
interface panel. This panel contains a single-turn sensitivity adjustment
knob, a two-position mode selector switch, along with three LED status
indicators.

IMPORTANT Damage to the single-turn sensitivity adjustment knob may

Using a screwdriver, the sensitivity can be increased (clockwise) or
decreased (counterclockwise) to meet the application requirements.
The factory default setting for all versions is maximum sensitivity.

The LaserSight photoelectric sensor also contains a two-position
selector switch. This switch is used to select either light or dark operate
mode of the sensor. In the light operate mode, the sensor output will
turn ON when the light is being reflected back to the sensor (reflector
for retroreflective, source for transmitted beam or target for diffuse). In
dark operate mode, the sensor output will turn OFF when no light is
being reflected back to it.

IMPORTANT After initial sensor configuration, confirm that the user

Sensor Alignment

The red LED indicator is an alignment aid which indicates that a
margin of 2X has been reached. This means that the sensor is receiving
at least 2 times the signal strength back from the target needed to trigger
an output signal. In general, it is desirable to have a higher margin to
help overcome any deteriorating environmental conditions, e.g. dust
buildup on the sensor's lens. When aligning the sensor, the best
performance can be obtained if this margin indicator is illuminated with
the target in place.

Mounting the Sensor

IMPORTANT

Securely mount the sensor on a firm, stable surface or support. A
mounting which is subject to excessive vibration or shifting may cause
intermittent operation. Adaptors and mounting brackets are available
for a flexible installation. The sensor is supplied with the hardware kit
129-130 which contains a plastic mounting nut, lock washer, 2 M5 x

0.8x 53 screws and nuts.
Once securely mounted, the sensor may be wired as indicated in the

wiring diagrams.
