Looking for a great value on a Laser Sensor for your earth moving machines? Check out the LS-B100. Fast to set up and easy to use, this affordable depth control sensor can be mounted to your equipment and working within minutes. This unit is packed full of features such as an Accuracy Mode and Battery Life Indicator. Plus, it has a Power Save/Auto Cut Off function to save your battery life. The LS-B100 is a low-cost grade indicate solution that makes any operator more productive.


With the added Slope and Plumb Indicators, your grading and excavating accuracies are tighter than ever with Topcon's LS-B110. Plus, the new LS-B 110 enables you to offset the "on-grade " position with one touch. This gives you an even greater working range. Compatible with Topcon's family of Control Boxes for all your earth moving equipment the LS-B110 can also be used in "automatic" mode to hydraulically control the elevation and/or the slope of the cutting edge. This takes your production and materials savings up to a whole new level.


The LS-B110W is a Laser Sensor with a Wireless Remote Display. It is loaded with all the time saving features as the other LS-B units and also perfect for your larger machines where the Sensor is out of view. This equipment offers the total solution in grade management. With the one touch "On Grade" matching, MC automatic capability and built-in Plumb and Slope Indicator, you can't go wrong. Put the LS-B110 W on your Dozer, then move it to your Scraper and then onto your Excavator. This equipment does it all on virtually all your machines.


The Remote Display puts the Laser Sensors information in the cab of the machine. Productivity increases on the job because the operator focuses on the grade information and not the Sensor itself. The operator can adjust the "On Grade" position without leaving the seat. No need to climb down to adjust the laser height or move the Sensor on the machine. Whether you are going deep with your excavator or grading with a drag scraper the RD-100W is wirelessly connected to the LS-B110W giving the operator constant, real time grade information.


Bright, easy-to-read, adjustable grade indication

Topcon's LS-B series receivers provide multi-color grade indication that can be seen even in the driest, dustiest conditions. The LS-B110W and RD-100W even offer the advantage of moving grade indication in to the operator cab should the receiver be out of operator line-of-site, or conditions are to severe to see the receiver.

All LS-B100/LS-B110 Series laser receivers offer four ongrade accuracies from .1" for tight tolerances to 1.17" for rough work. Receiver and laser* battery strength are displayed on the LED's as is laser HI alert (laser has been disturbed).

* Laser battery indication provided when used with a Topcon laser.

The LS-B110 and LS-B110W

In addition to ongrade precision, the LS-B110 Sereies receivers also provide:

  • ongrade offsets up to 3" below the laser beam at the touch of a button. No more resetting the laser!
  • Plumb indication providing visual confirmation that the cutting edge is horizontal on Dozers or scrapers, or that the stick is vertical when making a final cut to grade on excavators and backhoes. Plumb accuracy also offers a fine or course setting.


Versatile Mounting

Topcon's LS-B100 / LS-B110 Series receivers use mechanical "clamp" type mounts for sure, slip free placement on your machines. Finger knobs are placed on the front of the receivers to make it quick and easy to get to work.

Topcon offers a choice of mounting brackets to fit the way you work:

  • Magnetic pole for excavators and backhoes
  • Vibration pole for dozers, scrapers, and compactors


Be sure to let your Topcon dealer know what type of equipment your planning to use with your LS-B receiver and they'll make sure you having everything you need to get right to work.
