Topcon LS-B200 Machine Control Laser Receiver
W-9 and vendor pack with every quote
Shipped direct from the manufacturer
Topcon sells this receiver as two SKUs, an indicate-only LS-B200 and an automatic-mode LS-B200W, and picking the wrong one means an instrument that cannot run your in-cab control box.
01
Topcon sells this receiver as two SKUs, and only one of them runs automatic machine control
Topcon builds the LS-B200 family in two versions. The base LS-B200, part 1053268-03, runs indicate mode only: it shows the operator the grade and stops there. The LS-B200W, part 1063574-04, adds the ability to talk directly to Topcon's own in-cab control boxes. That is the hardware on a dozer or excavator that drives the blade automatically. Topcon's own catalog states the split plainly: automatic mode applications use the LS-B200W, indicate mode applications use the LS-B200. If your machine runs automatic control, the indicate-only LS-B200 is the wrong instrument, whatever else the spec sheet says. That single distinction, not the price, is the first question to answer.
02
The LS-B200W adds Bluetooth, RS-485, a wider capture window, and a mobile app; the LS-B200 has none of it
The base LS-B200 talks to nothing but its own power supply: its only interface is CAN, used for power alone. The LS-B200W adds RS-485, CAN, and Bluetooth, and pairs with Topcon's Laser Manager app on iOS or Android, which carries a one-time setup fee. The LS-B200W also reads a wider beam: its capture window, the strip on the receiver face that catches the laser, spans 250mm against the LS-B200's 175mm. Both variants share the same 360-degree detection angle and the same four selectable precision modes. Both also share the same 800-meter detection range, stated by Topcon as a diameter, not a radius.
03
The more capable SKU has the shorter battery life, 80 hours against 100
Topcon's own comparison table gives the base LS-B200 up to 100 hours on four alkaline batteries. The LS-B200W, with its added wireless hardware, runs up to 80 hours on the same batteries. The gap holds on the optional rechargeable pack too: 50 hours on the LS-B200, 40 on the LS-B200W. Neither variant ships with batteries in the box, per two independent dealers; Topcon does not publish a packing list either way. Choosing the LS-B200W for automatic mode means accepting a shorter runtime between changes, a real trade worth planning a shift around.
04
Detection range runs to 800 meters, a diameter figure, with four selectable precision modes
Both variants detect the beam from any direction across a full 360 degrees, out to an 800-meter (2,600-foot) diameter, identical on both SKUs. Precision is selectable in four modes. Mode 1 holds plus or minus 3mm, Mode 2 plus or minus 6mm, Mode 3 plus or minus 15mm, and Mode 4 plus or minus 30mm. On-grade matching tolerance runs 150mm on both. A wavelength range of 633 to 785 nanometers is not published by Topcon anywhere, not in its brochure, its catalog, or its own product pages. One independent dealer states the same figure; it is recorded here as unconfirmed by the manufacturer, not as a Topcon spec.
05
The rechargeable pack for this receiver is the BT83Q, and an older part number is still in circulation
Topcon's own channel parts list and its own product comparison page both name the BT83Q as the LS-B200 family's rechargeable pack, and they agree with each other. The BT-68Q is a legacy part built for the discontinued LS-B100 Series, a different receiver, and Topcon's parts list files it that way. One independent dealer still shows BT-68Q against this product in its own spec table while selling BT83Q as the correct battery on its own accessory page. If you are replacing a pack, call and confirm which one your unit takes before you order.
06
A built-in clamp mounts to dozers, excavators, backhoes, drag-boxes, and scrapers
The LS-B200 and LS-B200W both mount with a built-in mechanical clamp, no separate bracket needed for a standard fit. Topcon's own parts list adds two named accessories for dozer and excavator work, a magnetic mount bracket and a vibe pole. Both are grouped as current LS-B200-series parts, though the same list's own descriptions still tag them for the legacy LS-B100 Series. No Topcon material names a specific rotary laser this receiver is built to pair with. Pairing is a call to make with us before you buy, not an assumption from a spec sheet. Both variants carry an IP66 rating and run from -20 degrees C to 50 degrees C (-4 degrees F to 122 degrees F).
07 FOR UNIVERSITIES, COLLEGES AND GOVERNMENT AGENCIES
My Surveying Direct ships both SKUs direct from Topcon, and one call confirms which one your machine needs
Universities, colleges, and government agencies can order either SKU by purchase order, with W-9 and tax-exemption documentation on file. Both variants carry a one-year manufacturer warranty. Topcon's own materials do not state a packing list for the LS-B200 family. Two independent dealers describe a receiver, a hard carry case, a dry-cell battery holder, and a manual, batteries sold separately. Call us before you order, +1 888 850 6533, Monday to Friday, 9 to 5 Mountain Time. We will confirm which SKU matches your control box, what ships in your box, and the battery pack your unit takes.
