Series 9000 LaserSight Photoelectric Sensors

Description

The LaserSight 9000 is a Class 1 visible red laser sensor designed for the
detection of small parts in the packaging, material handling and
semi-conductor industries. This sensor offers multiple sensing
mode

s suitable for general purpose detection that can be easily

set

u

p 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.

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.

Transmitted Beam Models

1. Visually align the emitter and receiver units until the green
output LED turns ON (with light-operate mode) or turns OFF
(with dark-operate mode).

2. To ensure that the beam is centered, it is recommended to
sweep the emitter or receiver in the horizontal and vertical
plane and determine at what position the output indicator
turns ON and then turns OFF. Set the sensor midway between

After initial sensor configuration, ensure that the

Status Indicators

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

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.

Quick-disconnect connection is shown in the following diagrams. Pin numbers correspond to male connectors on the sensor.
