SitePro 7M Fiberglass Leveling Rod - Metric

The Topcon LS-B20W (Part No. 1063525-04) is a professional-grade wireless machine control laser receiver engineered for contractors who demand precise, efficient grade control without the limitations of traditional cabled setups. By integrating wireless communication directly into the receiver, the LS-B20W eliminates time-consuming cable runs between laser transmitters and heavy equipment, reducing setup overhead on large earthwork sites and multi-machine operations. Whether you're working with motor graders, bulldozers, or excavators, this receiver delivers the reliability and accuracy that Topcon's machine control platform is known for.

Product Overview & Jobsite Applications

The LS-B20W is purpose-built for contractors managing complex grading operations across expansive job sites. Its wireless capability allows multiple machines to receive simultaneous grade data from a single rotating laser, keeping an entire fleet on-grade without physical tethering. The receiver integrates directly into Topcon's digital site ecosystem, enabling synchronized cut/fill guidance and real-time grade corrections through compatible machine control displays. Backward compatibility with wired Topcon laser systems protects existing equipment investments while allowing a phased transition to fully wireless workflows.

Job Applications

Site Grading & Earthwork: Mount the LS-B20W on motor graders or bulldozers to maintain consistent cut/fill grades across large clearing and grading operations. The wireless connection keeps the machine on-grade without routing cables through cabs or over tracks.

Road Base Preparation: Use the receiver on a blade or dozer to achieve precise subbase elevations required for road construction, ensuring uniform compaction depth and eliminating costly overcuts.

Pad Construction: Building commercial or residential pads to tight tolerances is straightforward with synchronized laser grade control — the LS-B20W feeds real-time elevation data to the machine's control system for continuous automatic blade adjustments.

Multi-Machine Fleet Coordination: On large earthmoving projects with multiple graders or dozers working simultaneously, the LS-B20W allows each machine to receive wireless grade data from the same rotating laser, ensuring consistent elevations across the entire site without re-staking or manual checks.

Frequently Asked Questions

Is the Topcon LS-B20W compatible with non-Topcon laser systems?

The LS-B20W is designed and optimized for use within the Topcon laser ecosystem. While it may detect some third-party rotating lasers in wired mode, wireless functionality is specific to Topcon wireless-capable transmitters. For guaranteed performance, use with a compatible Topcon rotating laser.

Can the LS-B20W be used in both wired and wireless modes?

Yes. The LS-B20W supports both wired and wireless operation, making it backward compatible with existing cabled Topcon laser setups. This allows contractors to use the receiver on legacy equipment while taking advantage of wireless operation on newer or retrofitted machines.

How many machines can share one laser transmitter using the LS-B20W?

Multiple LS-B20W receivers can operate simultaneously from a single rotating laser transmitter, making it ideal for coordinating entire equipment fleets on large earthwork projects. The exact number of simultaneous receivers depends on the transmitter model and site conditions.
