Spectra Precision SP60 GNSS Machine Control Receiver

Wireless Precision Depth Control for Excavators and Heavy Equipment

The Topcon LS-B200W-MM is a professional-grade wireless laser receiver built for machine-mount applications on excavators, dozers, and graders. Designed to detect laser plane signals from rotary lasers, this receiver delivers real-time grade and depth guidance directly to equipment operators — without the clutter of cables running from the mast to the cab. Whether you're cutting to grade on a foundation dig or finishing a drainage swale, the LS-B200W-MM keeps your operator accurate and productive all day long.

Jobsite Overview and Applications

The LS-B200W-MM is engineered for contractors who need reliable, repeatable grade control across a wide range of earthmoving operations. Its wireless communication system transmits cut/fill guidance to a compatible cab display, eliminating wiring complications and reducing setup time. The included magnetic mount attaches directly to excavator blades, dozer cutting edges, or grader moldboards — no drilling, no permanent hardware. Plumb and tilt indication gives operators confidence that the mast and receiver are positioned correctly before the laser beam is acquired. This receiver is compatible with Topcon rotary lasers and integrates with Topcon's machine control ecosystem for grade-sensitive excavation and site preparation work.

Job Applications

Excavation and Foundation Digging: Set your rotary laser at finished floor elevation, mount the LS-B200W-MM to the excavator bucket or blade, and your operator gets live cut depth feedback in the cab — eliminating over-dig and reducing backfill costs.

Site Grading and Earthwork: On large grading operations with dozers or motor graders, the wireless receiver keeps the cab display fed with real-time on-grade, cut, and fill data across the full width of each pass.

Drainage and Swale Construction: Precise depth control is critical when cutting drainage channels. The LS-B200W-MM gives operators the accuracy needed to maintain consistent slope and invert elevations without constant manual checking.

Utility Trench Preparation: When trenching for utilities, maintaining consistent depth and grade protects pipe flow requirements. Wireless feedback from the LS-B200W-MM reduces the need for manual rod checks and speeds up trench production.

Frequently Asked Questions

Does the LS-B200W-MM work with any rotary laser, or only Topcon lasers?

The LS-B200W-MM is optimized for use with Topcon rotary lasers and is designed to integrate with Topcon's machine control display ecosystem. While the receiver may detect signals from other manufacturers' lasers, full wireless cab display functionality and system integration is confirmed with compatible Topcon laser and display units. Contact Express Tools for compatibility guidance with your specific setup.

How does the magnetic mount attach to the machine?

The magnetic mount uses a strong-hold magnet base that clamps directly to the steel cutting edge, blade, or moldboard of your excavator, dozer, or grader. No drilling or welding is required. The mount can be repositioned or moved between machines quickly, making it practical for contractors running multiple pieces of equipment.

What does the plumb and tilt indication feature do?

The plumb and tilt indicators on the LS-B200W-MM alert the operator or ground crew if the receiver mast is not properly vertical or if the receiver has shifted to an angle that could affect reading accuracy. This is especially useful on uneven terrain where the machine itself may be on a slope, ensuring grade data stays reliable.

What display unit is needed to read the wireless signal in the cab?

The LS-B200W-MM transmits wirelessly to a compatible Topcon machine control cab display. The specific display required depends on your machine control configuration. Express Tools can help you identify the correct cab display and any additional components needed to complete your wireless machine control setup.
