The Topcon LS-B200W/BS is a professional-grade wireless laser machine control receiver designed for excavators, graders, and dozers operating in demanding grading and excavation environments. By eliminating hardwired cable runs between the receiver and cab display, the LS-B200W/BS reduces downtime from tangled or severed cables and gives operators the freedom to reposition the mast without rewiring. Whether you're cutting precise slopes on a drainage channel or dialing in subgrade elevations for a foundation pour, this receiver delivers the accuracy and reliability contractors depend on.
Overview & Jobsite Applications
The LS-B200W/BS combines a high-sensitivity laser receiver with integrated plumb and tilt sensors, transmitting all data wirelessly via 2.4 GHz to a compatible cab-mounted display. The result is a complete picture of machine attitude—grade, plumb, and tilt simultaneously—without the clutter of routed cables through a boom or stick. The unit is housed in a ruggedized enclosure rated for outdoor use and is compatible with Topcon's rotating laser systems and MC-R3 wireless machine control displays.

Key Features
- Wireless 2.4 GHz Transmission: Eliminates cable routing through excavator boom and stick arms, reducing snag points and maintenance headaches on busy jobsites
- Integrated Plumb & Tilt Sensors: Monitor machine attitude in real time alongside laser grade data — essential for foundation work, pipe laying, and slope-critical excavation
- Wide Reception Band: Nearly 12 inches of detection height captures the laser beam even during machine movement, minimizing signal interruptions
- BS Battery System: The /BS suffix denotes inclusion of the rechargeable battery pack and charger — a complete, ready-to-run kit out of the box
- Rugged IP66 Housing: Sealed against high-pressure water jets and total dust ingress, built to survive muddy, wet, and high-vibration machine environments
- Compatible with Topcon Rotating Lasers: Works seamlessly with Topcon RL-H5A, RL-200, and other series rotating laser levels commonly used in machine control setups
Job Applications
Drainage & Slope Grading: The simultaneous grade and tilt readout lets operators maintain precise cross-slopes on drainage swales and detention basins without constant surveyor check-ins.
Foundation Excavation: Plumb monitoring ensures excavator bucket orientation stays consistent when cutting vertical walls, reducing over-excavation and costly backfill.
Subgrade Preparation: Use the wide reception band to maintain consistent cut depth across large pad areas, keeping the laser signal locked even when the dozer blade rises and falls over rough terrain.
Utility Trenching: Grade sensor data transmitted wirelessly to the cab display keeps operators on target grade for gravity sewer and storm drain installs without stopping to manually check elevations.

Frequently Asked Questions
- Does the LS-B200W/BS require a specific Topcon display to receive wireless data?
- Yes, the LS-B200W/BS is designed to pair with Topcon's MC-R3 wireless cab display or other compatible Topcon machine control indicators that support 2.4 GHz wireless reception. It is not compatible with third-party generic displays without an appropriate wireless adapter.
- What does the "/BS" designation mean in the model number?
- The "/BS" indicates that this package includes the BS rechargeable battery system — the battery pack and charger are bundled with the receiver. This makes it a complete, ready-to-deploy kit rather than requiring a separate battery purchase.
- Can the LS-B200W/BS be used with any rotating laser, or only Topcon models?
- The receiver's photodiode detection system is designed to detect the laser beam from most 635–690 nm red rotating laser levels. It works best and is factory-optimized for Topcon rotating lasers, but it will typically detect beams from other major brands. For guaranteed compatibility in critical-grade applications, pairing with a Topcon rotating laser is recommended.
- How far can the wireless signal transmit from the receiver to the cab display?
- The 2.4 GHz wireless link between the LS-B200W/BS and the MC-R3 cab display is rated for reliable transmission up to approximately 100 meters (330 ft) in open-air conditions. On a standard excavator, where the receiver is mounted on the stick and the display is in the cab, the effective range is well within this limit under normal operating conditions.
