The Topcon LS-B200W (model 1063574-04) is a professional-grade wireless laser receiver engineered for permanent cab-mounted installation on excavators, dozers, scrapers, and other grading equipment. Unlike handheld detectors passed between crew members, the LS-B200W delivers continuous real-time grade information directly to the operator without anyone leaving the machine. The fully wireless design eliminates cable routing through articulating booms, rotating cabs, and tight engine compartments — cutting installation time dramatically and eliminating cable damage as a maintenance headache on the jobsite.
Product Overview
Designed for contractors who demand accuracy and uptime on finish grading, mass excavation, and site prep projects, the LS-B200W pairs with Topcon rotating laser levels to give operators a bright, easy-to-read display of their cut/fill position relative to grade. The large LED indicator bar is legible in direct sunlight and can be read at a glance from the operator seat, keeping the machine moving and reducing the need for grade checkers on the ground. The wireless PS module communicates reliably across the jobsite, and the rugged housing stands up to the vibration, dust, and moisture exposure that machine-mounted equipment endures every shift.

Job Applications
Finish Grading & Subgrade Prep: Keep excavators and motor graders on target elevation during subgrade preparation without relying on grade checkers walking behind the machine. The LS-B200W delivers instant cut/fill feedback so operators hold grade through the entire pass.
Pond & Basin Excavation: Establish and maintain precise bottom elevations on retention ponds, detention basins, and irrigation channels where consistent depth across a large footprint is critical to drainage performance.
Dozer Spread Work: Mount the LS-B200W on a dozer cab and reference a site laser to control fill spread elevations on parking lots, building pads, and road subbase layers — reducing overcut and excess material costs.
Utility Trench Grading: Maintain consistent trench bottom elevations for gravity-flow sewer and drainage pipe installation, where even minor grade errors cause costly rework or failed inspections.

Frequently Asked Questions
- Does the LS-B200W require a separate wireless module to operate?
- Yes — the LS-B200W uses Topcon's PS wireless system. The PS module must be mounted on the rotating laser level to enable wireless communication with the receiver. The PS module is sold separately; confirm compatibility with your existing laser before ordering.
- Can this receiver be used on multiple machines on the same job?
- The PS wireless system is designed for dedicated pairing between a specific laser and receiver. Running multiple LS-B200W units on a single jobsite is possible, but each receiver must be paired to its own designated laser to avoid signal conflicts and grade errors.
- What rotating lasers are compatible with the LS-B200W?
- The LS-B200W is compatible with Topcon rotating lasers equipped with the PS wireless output, including models in the RL-H5 and RL-SV series. Always verify PS wireless capability on your specific laser model before purchasing the receiver.
- Is the LS-B200W waterproof enough for outdoor machine use?
- The LS-B200W carries an IP66 ingress protection rating, meaning it is fully dust-tight and protected against powerful water jets from any direction. It is built to handle rain, wash-down, and normal jobsite moisture exposure when properly installed on the machine cab.
