The emitted light is collimated through a lens, which produces a very narrow laser beam. The laser beam bounces off the target, scattering some of its light through the sensor’s receiving lens to a photodiode, which creates an electrical pulse. The time interval between the two electrical pulses (transmitting and receiving the beam) is used to calculate the distance to the target, using the speed of light as a constant. Multiple pulses are evaluated by the sensor’s microprocessor, which calculates the appropriate output value. The analog output provides a variable signal (4 mA to 20 mA or 0 V dc to 10 V dc, depending on model) that is proportional to the target’s position within the user-programmed analog window limits. The discrete (switched) output energizes whenever the target is located between the user- programmed discrete window limits. Window limits for the analog and discrete outputs may be the same, or they may be programmed independently. 1 See Banner website (www.bannerengineering.com) for information on analog/discrete models. 2 To order the 9 m cable models, add the 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. 3 Retroreflective range specified using included model BRT-TVHG-8X10P high-grade target.

aversion to bright light and stare directly into the laser beam. that laser emission is occurring.

  • Do not stare at the laser.
  • Do not point the laser at a person’s eye.
  • Mount open laser beam paths either above or below eye level, where practical.
  • Terminate the beam emitted by the laser product at the end of its useful path. Configuration Instructions Sensor Power-Up and Laser-Enable Power up the sensor for 30 minutes to allow the sensor’s internal temperature to stabilize before operating or attempting to program the sensor. If the sensor is used in applications where the temperature is several degrees higher or lower than the ambient temperature, allow the sensor to stabilize in that condition before programming the window limits. The range decreases when the sensor warms up. The Laser-Enable feature allows the sensor to be continually powered and enabled only when being used. This eliminates the need for the extended warm-up period between uses. The sensor’s red Signal LED indicates the condition of the received signal from the object being measured. When programming the window limits, this LED must be on (not flashing) for the sensor to accept the setting. To ensure the received signal will not be marginal during operation, move the target object 300 mm beyond the furthest desired switch point during setup and verify the signal LED is still on.
