Topcon LS-B200-2/PS Laser Machine Display Receiver

Affordable Grade Indication for Machine Control Applications

The Topcon LS-B200-2/PS Machine Display Receiver gives working contractors a reliable, cost-effective solution for maintaining grade accuracy on the job. Designed to mount directly to machine-mounted masts on excavators, dozers, graders, and track loaders, this receiver captures signals from Topcon rotating laser transmitters and delivers immediate visual grade feedback to operators through a bright, easy-to-read LED display. Whether you're cutting a pad, finishing a slope, or digging a trench to depth, the LS-B200-2/PS keeps your operators on grade without the overhead of a full GPS or 3D control system.

Overview & Jobsite Applications

The LS-B200-2/PS is engineered for contractors who need dependable single-axis grade control across a variety of earthmoving applications. The receiver pairs with Topcon rotating laser levels to provide continuous on-grade indication through its multi-LED display panel. The large detection window captures the laser beam effectively even on dusty or vibration-heavy jobsites, and the unit is built to withstand the rugged demands of construction equipment operation. This receiver is an ideal entry point into machine control for smaller fleets and owner-operators looking to improve efficiency without a major capital investment.

Job Applications

Site Preparation & Pad Grading: Mount the LS-B200-2/PS on a dozer or motor grader to maintain consistent elevation across large pads and building sites. The real-time display keeps blade operators cutting to exact grade without constant manual checks.

Trench Excavation: Attach the receiver to an excavator mast to control trench depth and slope on utility, drainage, and foundation projects. Operators can hit target elevation consistently across the trench run.

Slope & Drainage Control: Use the receiver with a grade-capable rotating laser to maintain precise cross-slopes and drainage gradients on parking lots, roadways, and athletic fields.

Track Loader & Compact Equipment: The LS-B200-2/PS is compact enough to work effectively on track loaders and compact excavators, bringing grade control capability to smaller machines that typically operate without automated systems.

Frequently Asked Questions

What laser transmitters are compatible with the LS-B200-2/PS?

The LS-B200-2/PS is designed to work with Topcon rotating laser transmitters including the RL-H5A, RL-200 series, and other compatible Topcon grade lasers. For specific compatibility questions, contact our team at Express Tools before purchasing.

Does the LS-B200-2/PS require batteries?

No. The LS-B200-2/PS uses a PS connector to draw power directly from the machine's electrical system, eliminating the need for onboard batteries and reducing maintenance requirements on the jobsite.

What machines can the LS-B200-2/PS be mounted on?

This receiver is suitable for a wide range of earthmoving equipment including excavators, bulldozers, motor graders, and track loaders. It mounts to a standard machine mast and bracket system that is sold separately.

Is the LS-B200-2/PS a full machine control system?

No — the LS-B200-2/PS provides visual grade indication only. It displays whether the blade or bucket is on-grade, above, or below target elevation, but does not automatically control the machine. It is a cost-effective manual-assist solution rather than a fully automated 2D or 3D control system.
