LT7 Long-Range Time-of-Flight Laser Sensor
Self-contained retroreflective- and diffuse-mode laser distance sensors
Printed in USA
02/05
P/N 120244
Features
• Extremely long range: diffuse model up to 10 m with white target, up to 7 m with
gray target, up to 3 m with black target; up to 250 m for retroreflective models
• Visible pilot laser for easy alignment
• Multiple outputs in each model:
- Discrete outputs can be used for precision background suppression
- 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 hundredths of an inch
or millimeters)
• RS422- or SSI-compatible serial connection options
Models
* Requires a mating cable; see page 20.
** Diffuse-mode range specified using a 90% reflectance white card.
Retroreflective-mode range specified using the appropriate specified retro target; see page 22.
WARNING . . .
Not To Be Used for Personnel Protection
Never use these products as sensing devices for personnel protection. Doing so could lead to serious injury or death.
These sensors do NOT include the self-checking redundant circuitry necessary to allow their use in personnel safety applications.
A sensor failure or malfunction can cause either an energized or de-energized sensor output condition. Consult your current
Banner Safety Products catalog for safety products which meet OSHA, ANSI and IEC standards for personnel protection.
