Laser rangefinder module, chosen by range
Board-level modules · 9 m to 18 km · published single-unit prices · updated 2026-10-23
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.
Selection table
| Range band | Class | Interface | Blind zone | Published unit price |
|---|---|---|---|---|
| 0.05–9 m | LRF10VB (940 nm DToF) | UART-TTL | 5 cm | $10 |
| 0.05–20 m | LRF22VB | UART-TTL | 5 cm | $12 |
| 0.05–50 m | LRF50VB / LRF50H | UART-TTL | 5 cm | $70 / $100 |
| 0.05–100 m | LRF100H (9–36 V) | UART-TTL | 5 cm | $200 |
| 0.05–600 m | LRF600H | UART-TTL | 5 cm | $350 |
| 4–1,000 m | LR1000E2 (905 nm) | UART-TTL | 4 m | $80 |
| 4–2,000 m | LR2000E2 | UART-TTL | 4 m | $120 |
| ≥3,000 m | LRF3000A1 | UART-TTL | 4 m | $200 |
| ≥3,000 m eye-safe | LRF0105C (1535 nm) | UART-TTL | <15 m | $500 |
| ≥6,000 m eye-safe | LRF0610C / LRF0609C | UART-TTL | <15 m | $1,000 / $1,600 |
| ≥10,000 m eye-safe | LRF1017C | UART-TTL | <15 m | $3,000 |
| ≥18,000 m eye-safe | LRF1830C | UART-TTL | <15 m | $7,000 |
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.
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@erdimail.com and it will be corrected with the date noted.
