Hamar Laser’s new A-1519 and A-1520 Type II Universal Wireless targets operate in both single and dual axis modes (depending on the readout used) and are available in frequencies of 900 MHz or 2.4 GHz.

In single axis scanning mode, the targets cans be used with Hamar Laser’s continuously sweeping lasers (L-730/L-740 series) for measuring the flatness, straightness, squareness and parallelism of both machine tools and rolls. Either the R-1310-900 PDA Readout (displaying simultaneous readings from up to four targets) or the new R-1307 Readout (displaying readings from up to two targets) may be used in single-axis mode.

When the targets operate in dual axis mode with the L-705 Bore Laser, the new R-1307 Universal Readout must be used.

The targets provide wireless radio communication with up to a 1-inch (25 mm) measuring range, an electronic “zero” function and an operating range of 100 feet (30.5 mm) from laser to target. The A-1519 has a resolution of .00002" (0.5 microns). For applications where greater accuracy is needed, such as surface plates, the A-1520 has a resolution of .00001" (0.25 microns).

The targets feature fully linearized, position-sensitive detectors with automatic background- light correction for extremely accurate readings.

Both the A-1519 and A-1520 can easily be converted to a height gage, as the center of the target has been set to a tightly-controlled dimension. Attach the 2.565" spacer to the base of the target and the exact dimension from laser pane to the measured surface can be obtained. Optional precision spacers are available in 1", 2", 3£ and 6" sizes, all of which are accurate to .0003" (O.0075mm).

The A-1519 and A-1520 packages include the target, a magnetic base, a 2.565" precision spacer with spherical tip and three insert posts (6.25", 4" and 2" or 158.8mm 101.6mm and 50.8mm) for coarse height adjustment.

The targets require the R-1310 PDA Receiver or the A-910 Computer Radio Base Station (900 MHz or 2.4 GHz) to display target data in single-axis mode.Both radio transceivers have frequency hopping to minimize interference from other devices using the same or similar frequencies. Targets can change channels within their frequency range so two or more independent systems can be used in the same working area without interfering with each other.

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 indicators provide immediate “off target” status.

Powered by two internal lithium ion batteries for long life and usage. 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 300 feet (91 M) maximum.
