Self-contained Retroreflective- and Diffuse-mode Laser Distance Sensors

• Diffuse model with extremely long distance ranges:

◦ Up to 3 meters with black target

◦

Up to 7 meters with gray target

◦

Up to 10 meters with white target

• Retroreflective model range: up to 250 meters

• Visible pilot laser for easy alignment

• Multiple outputs in each model: discrete outputs can be used for precision

background suppression; and alarm outputs together with display provide easy

troubleshooting

◦

Diffuse models: Two discrete (PNP) plus 2 alarm outputs, and 4-20 mA

analog

◦

Retroreflective models: Two discrete (PNP) plus 2 alarm outputs

• Fast, easy-to-use TEACH-mode programming via integrated push-buttons or serial

interface (no potentiometer adjustments)

• Ongoing LCD display of sensing distance selectable in millimeters or one-

hundredths of one inch

• RS422- or SSI-compatible serial connection options

WARNING: Not To Be Used for Personnel Protection

Never use this device as a sensing device for personnel protection. Doing so could lead to serious injury or

death. This device does not include the self-checking redundant circuitry necessary to allow its use in personnel

safety applications. A sensor failure or malfunction can cause either an energized or de-energized sensor output

condition.

Programming

Buttons

The sensor has an LCD display and 3 push buttons, which control all programming

functions. Serial interface programming can also be accomplished via SSI or RS422.

Four status indicator LEDs on the sensor front/top provide ongoing status of power and

outputs.

The sensor has a 2-line LCD display and four LED indicators for ongoing indication of

sensing status: Power ON, Alarm, and Outputs 1 and 2.

In Run mode, the current measured value is displayed in the top line of the sensor's

display, in millimeters or hundredths of an inch, as selected.

1 Requires a mating cable.

2 Diffuse-mode range specified using a 90% reflective white card. Retroreflective-mode range specified using the specified retroreflective target.
