The LT7 Long-Range Time-of-Flight Laser Sensor. 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 4 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. The sensor uses an infrared Class 1 laser for sensing, and a visible red Class 2 laser (or Pilot laser) for alignment.

Both lasers are aimed at the identical target spot. The laser beams are collimated to focus a compact spot, even at long sensing distances.

LT7 Features Include: 

•  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
