Topcon LS-B10 Machine Control Laser Receiver 312660103 - Non-Wireless

The Topcon LS-B10 Machine Control Laser Receiver is purpose-built for contractors who need dependable, no-frills grade feedback on the blade. Designed for use with standard rotating laser transmitters, the LS-B10 delivers clear up/down/on-grade indication through a bright LED display that operators can read in full daylight. Without wireless components to fail or interfere, this receiver is the go-to choice for fleets running multiple machines on the same site or operating in RF-congested environments.

Overview & Jobsite Applications

The Topcon LS-B10 mounts directly to the blade mast of a dozer or motor grader and connects to a compatible machine control valve box or grade display panel. It reads the rotating laser plane established by a site transmitter and feeds real-time grade data to the operator cab. Because it operates entirely without wireless communication, it eliminates the dependency on radio signals and works reliably even where multiple laser transmitters are running simultaneously across a large site. It is an ideal solution for earthwork contractors, utility grading crews, and site development operations where simplicity and uptime are the priority.

• Wide laser reception window: Captures the rotating laser beam quickly and accurately across a broad detection range
• Rugged housing: Built to withstand vibration, dust, and moisture in demanding machine control environments
• Direct mast mounting: Integrates cleanly with standard dozer and grader blade mast setups
• Fail-safe simplicity: Fewer components mean fewer failure points — ideal for rental fleets and high-utilization machines

Job Applications

• Dozer rough grading: Mount the LS-B10 on a dozer blade mast to establish consistent cut/fill grades during mass earthwork operations without relying on wireless grade transmission
• Motor grader finish grading: Provide blade operators with real-time laser grade feedback for finish grading on parking lots, road subbase, and pad sites
• Utility trench backfill: Maintain specified backfill slope and compaction grades across linear trench runs using a single rotating laser reference plane
• Multi-machine sites: Deploy across a fleet of dozers or graders operating simultaneously — no wireless channel conflicts or signal contention between machines

Frequently Asked Questions

Does the Topcon LS-B10 require a wireless-capable laser transmitter?

No. The LS-B10 is a non-wireless receiver that works with any standard rotating laser transmitter. It reads the laser plane optically and does not require or support radio frequency communication between the receiver and transmitter.

What machines is the LS-B10 compatible with?

The LS-B10 is designed for use on dozers and motor graders equipped with a blade mast and a compatible machine control valve box or grade display. It integrates with Topcon machine control systems and is appropriate for most standard earthmoving machines used in site grading applications.

Can multiple LS-B10 receivers operate on the same job site at the same time?

Yes. Because the LS-B10 is non-wireless, there is no radio frequency conflict between units. Multiple receivers can operate simultaneously on the same site without interference, making it well-suited for large fleet deployments.

What is the difference between the LS-B10 and the LS-B10W?

The LS-B10W adds wireless communication capability, allowing it to receive grade data transmitted wirelessly from a compatible Topcon laser. The LS-B10 reads the laser beam optically only. For sites without wireless transmitters or where RF interference is a concern, the LS-B10 is the more reliable and cost-effective choice.
