How do I choose a range band?

Start from the nearest target the module must read, not the farthest. A 2 km module with a 4 m blind zone cannot do terrain following at 0.3 m; the 0.05 m classes are the only ones that reach the ground. Pick the smallest band that clears the working distance, then check supply and interface.

Do you publish prices?

Yes. The published single-unit price for every class is on the price ladder page, dated 2026-10-23. Volume tiers sit below those numbers and are quoted per order.

When does 1535 nm make sense?

Past a few kilometres, or wherever people may be near the beam. The 1535 nm branch is the eye-safe path in this catalogue; it costs more per metre than the 905 nm classes, and the price step from 3 km to 18 km is the largest in the table.

What interface do the modules use?

The short-range VB and H classes and the 905 nm E-series ship UART-TTL with a documented frame and checksum. Some long-range 1535 nm classes publish RS-422 — the interface is stated on each model page, and there is no native analog or 4–20 mA output.

Most selection pages start with price. Buyers usually start with a distance and a target. This table starts the same way: pick the range band you actually need, then check the blind zone, the interface, and the published single-unit price for that class.

Prices are the published single-unit tier (the 1–N piece band) as of 2026-10-23, taken from the public price page. Volume tiers are lower and are quoted per order. Long-range figures are stated against a 2.3 × 2.3 m reference target unless noted — compare the test condition, not the headline number.

Range bands at a glance

The same catalogue read across range bands instead of down a price list. Figures are the published single-unit table of 2026-10-23; the model page is the citable source for each class.

Three things that decide the fit, beyond range

Blind zone, not maximum range. A 2 km module that cannot read below 4 m will not do terrain following at 0.3 m. If your application touches the ground, the 0.05 m classes (VB and H series) are the only ones that qualify.
Supply and interface. The H series takes 9–36 V DC directly, which matters on a 24 V machine; the E and VB series want 3.3–5 V. Everything ships UART-TTL with a documented frame and checksum. There is no native analog or 4–20 mA output, and no native RS485 — a host-side transceiver solves the latter.
Eye safety, if people are near the beam. 905 nm reaches a few kilometres cheaply; past that, 1535 nm is the eye-safe path and it costs more per metre. That step change is the largest single jump in the table.

What this page is not

It is not a comparison against every supplier, and it does not quote competitors' specifications from memory — if a number is not from our own catalogue, it is not here. If you are weighing us against a specific industrial instrument, the honest axis is usually board-level module vs cased instrument (housing, IP rating, analog output, local service contract), not model against model.

Source and correction policy

Every figure above comes from the published catalogue on 2026-10-23. Where two source documents disagree for a model, the model page states the conflict rather than picking one value, and the datasheet governs the order. If a number here stops matching the catalogue, that is a bug: write to tommy@mail.erdilrf.com and it will be corrected with the date noted.
