LT3 Long-Range Time-of-Flight Laser Sensor
Self-contained laser distance sensor, two discrete outputs
Printed in USA
02/05
P/N 68503 rev. C
Features
• Extremely long range: 5 m with white targets, or 3 m with gray targets for diffuse
mode sensors, up to 50 m for retroreflective models
• Two discrete (switched) outputs in each sensor, with independent window limits
†
• Discrete outputs can be used for precision background suppression
• Output select wire is used to choose either NPN or PNP outputs (see hookups)
• Fast, easy-to-use integrated push-button TEACH-mode programming; no
potentiometer adjustments
• Remote TEACH function for security and convenience
• Output response is programmable for three speeds
• High-grade retroreflective target included with each retroreflective-mode sensor
• Choose 2 m or 9 m unterminated cable, or 8-pin Euro-style swivel QD connector
• Rugged construction withstands demanding sensing environments; rated IEC
IP67, NEMA 6
Models
* 9 m cables are available by adding suffix “W/30” to the model number of any cabled
sensor (e.g., LT3BD W/30). A model with a QD connector requires a mating cable;
see page 11.
** Retroreflective range specified using included model BRT-TVHG-8X10P
high-grade target.

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.

CAUTION
. . .
This
sensor contains no user-
serviceable components.
Do not attempt to repair.
Incorrect component values may produce
hazardous laser radiation levels.
