Topcon LS-B200-MM Laser Machine Display Receiver

Metric Grade Control for Machine-Mounted Applications

The Topcon LS-B200-MM is a professional-grade machine laser receiver engineered for contractors who work in metric millimeter measurements. Designed to mount directly on the blade or boom of excavators, dozers, and graders, this rugged receiver captures rotating laser signals and delivers instant visual grade feedback through a large LED display — keeping operators precisely on grade without stopping for manual checks. If your jobsite specifications call for millimeter increments, the LS-B200-MM is purpose-built to match those standards right out of the box.

Overview and Jobsite Applications

The LS-B200-MM pairs with any rotating laser transmitter to create a complete, two-person-free grade control system for earthwork and sitework operations. The receiver's wide detection window captures the laser beam across a broad sensing range, while the large LED indicator bars give operators clear cut/fill/on-grade signals from inside the cab — even in bright sunlight. The MM configuration displays grade offset in millimeter increments, eliminating any need for field conversion and reducing the risk of measurement errors on metric-spec projects. Whether you're cutting subgrade for a foundation, trimming a road shoulder, or rough-grading a commercial pad, the LS-B200-MM delivers the real-time feedback your operators need to stay productive and accurate.

Key Features

• Millimeter display increments for metric jobsite specifications — no manual unit conversion needed
• Large, high-brightness LED display provides clear cut, fill, and on-grade indication from inside the cab
• Wide laser detection window captures rotating beam across a broad sensing band for consistent signal acquisition
• Rugged, machine-duty housing built to withstand vibration, dust, and moisture on active construction sites
• Machine power input eliminates battery dependency — connect directly to equipment electrical system
• Compatible with Topcon rotating lasers and most competing rotating laser transmitters
• Mast-mount design installs quickly on blade poles, boom arms, or screed masts
• Audio and visual alarm indicators alert the operator when the laser beam is lost or grade deviation exceeds threshold

Job Applications

Excavation and Trenching: Mount the LS-B200-MM on the excavator boom to give operators continuous depth feedback during foundation excavation, utility trenching, or detention pond grading — maintaining consistent cut depth without stopping for grade checks.

Dozer Rough Grading: Attach to the blade mast on a crawler dozer for efficient mass earthmoving on commercial or residential pads. The LED display keeps the operator in the cut zone and reduces over-excavation that costs time and material to correct.

Road and Parking Lot Subgrade: Use with a motor grader or dozer to trim subgrade to finished elevation across large paving areas. Millimeter display increments support the tight tolerances required before base course placement.

Screed and Fine Grading: Compatible with screed mast setups for fine grading operations where metric elevation control is specified by the engineer or owner, ensuring the finished surface meets plan elevation before inspection.

Frequently Asked Questions

What is the difference between the Topcon LS-B200-MM and the standard LS-B200?

The only difference is the display unit configuration. The LS-B200-MM shows grade offset in millimeter increments, while the standard LS-B200 displays in inches and fractions. Both use the same rugged housing, LED display, and wide-band laser sensor — the MM version is simply calibrated for metric jobsite specifications.

Will the LS-B200-MM work with laser transmitters from other brands?

Yes. The LS-B200-MM is designed to receive the signal from most rotating laser transmitters, not just Topcon models. It is compatible with lasers from Spectra, Leica, DeWalt, and other major brands that produce a standard rotating visible or red laser beam. Always verify frequency compatibility with your specific transmitter model before purchasing.

Does the LS-B200-MM require batteries, or does it run on machine power?

The LS-B200-MM is designed for machine power input, connecting directly to your equipment's 12V or 24V electrical system. This eliminates the need for battery changes during long shifts and ensures the receiver stays powered as long as the machine is running.

What types of machines is the LS-B200-MM compatible with?

The LS-B200-MM is compatible with any machine that uses a mast-mounted receiver setup, including excavators, crawler dozers, motor graders, scrapers, and compactors. It can also be adapted for use on paving screed masts. The key requirement is a standard mounting mast and access to machine power for the display unit.
