A-1519-2.4XBE Single-Axis Wireless Target

A-1519-2.4XBE Single-Axis Wireless Target


The A-1519-2.4XBE Single-Axis, Wireless Target has a very high resolution of .00002 in. (0.0005 mm) and accuracy with a large measuring range of ±.55 (±14 mm).  For higher-accuracy applications, the A-1520-2.4XBE Target, which has double the resolution and accuracy.  Both targets are used with all of HLI’s scanning lasers and operate with Xbee® radio technology that allows communication with up to 99 targets at the same time by using a robust, frequency-hopping radio technology. The data for these targets updates in real time and is sent either to a handheld PDA or a Windows®-based laptop or tablet.


  • Caster Segments
  • Boring Mills and Large Lathes
  • Gantry, Spar Mills and VTLs
  • Horizontal & Vertical Machining Centers
  • Injection Molding Machines
  • Machine Bed Leveling
  • Presses
  • Roll Alignment


  • Operate in both Single and Dual-Axis Modes (depending on the readout used) and use XBee® radio technology:
    • Single-Axis Scanning Mode – used with Hamar Laser’s continuously sweeping lasers (L-702SP & L-730/L-740 series) for measuring the flatness, straightness, squareness and parallelism of both machine tools and rolls.
    • Dual-Axis Mode – used to detect non-rotating laser beams in such applications as steam turbine bore alignment.
  • Features 2-axis, super-linear, position-sensitive detectors (PSDs) with automatic background-light correction for extremely accurate readings.
  • Several options are available to display the target data:
    • The R-1357-2.4XBE Rugged PDA display
    • The R-1307-2.4XBE Readout for 2 A-1519 targets
    • R-1307W-2.4XBE Readout for 2 A-1519 targets
    • R-1308 Single-Axis Readout
    • A-910-2.4XBE Computer Interface for use on a laptop.
  • Resolution of .00002 in. (0.0005 mm) and a measuring range of ± .55 in. (± 14 mm)
  • Linearized accuracy of ± .00015 in. (±0.0038 mm).
  • Targets can be used out to 100 feet (30.5 mm) from the laser.
  • The A-1519 package include the target, a magnetic base and three insert posts: 6.25 in., 4 in., and 2 in. (158.8 mm, 101.6 mm and 50.8 mm) for coarse height adjustment.
  • Completely automatic on/off operation with no switches, wires or connections. The target activates when the laser beam sweeps across the target cell and flashing target LEDs provide immediate “on/off target” status.
  • Powered by 2 internal lithium-ion batteries for up to 11.5 hours of continuous use. Comes with AC adapter/charger, low battery and charging indicators.
  • Targets can also be charged with the optional A-1519CS-4 Charging Station that charges up to 4 targets simultaneously.
  • Communication working distance (PDA/PC Base Station to target) is 150 feet (45 m) or greater.
