Banner Engineering LE Series Dual Discrete Laser Sensors

Banner Engineering’s LE250 and LE550 Dual Discrete laser sensors are the latest additions to the L-Gage LE family. These sensors, which are designed with the same robust housing, intuitive user interface and linear array technology as earlier analog models, offer high performance across difficult targets from shiny metal and black rubber.

The LE250 and LE550 Dual Discrete models provide value when you don’t want to incur the cost of an analog input card or the complexity sometimes associated with properly scaling an analog signal. The two, independently configurable, discrete outputs can be setup as single switch points or sensing windows for simple part detection and feedback on position. For example, by utilizing two overlapping windows, you can indicate if the target is correctly positioned, too close, too far, or not present.

The dual discrete versions of the LE250 and LE550 offer the same range, repeatability and spot size options as the analog versions. The LE550 provides a sensing range up to 1000 mm and a larger spot size, for better averaging across larger areas. The LE250’s optics have been optimized for improved performance over the 100 to 400 mm range. With a repeatability as small as 0.02 mm out to 250 mm, and 0.2 mm at 400 mm.


  • Ready to measure from 100mm up to 1000mm out of the box.
  • Linear array provides repeatability and accuracy for challenging targets.
  • Easy to set up and use with a two-line, eight-character display.
  • Visible class 2 laser for small spot size and easy alignment.
