ILR3800-100

Measuring ranges by target type
White target with 80% reflectance: measuring distance 0.05–100 m; net measuring span 99.95 m.
With a suitable reflector film: measuring distance 35–150 m; net span 115 m. The reflector minimum distance differs from the minimum for a white target.
Range depends on target reflectance and measurement conditions. The 150 m endpoint is not a net span. Source: Micro-Epsilon English International specifications.

Frequently asked questions

Answers to the most common questions about our products and services

Without a reflector the start is 0.05 m. Range ends are 30 m for black at 6% reflectivity, 70 m for grey at 40%, and 100 m for white at 80%, giving net spans of 29.95, 69.95 and 99.95 m respectively. With reflector film the interval is 35–150 m: a 115 m net span with a different start distance.

The cited specification does not establish that. Linearity below ±1 mm was measured over 0.05–20 m with a statistical spread of 2σ. It must not automatically be extended to the full white-target or reflector range.

The manufacturer specifies repeatability below 300 µm at a measuring frequency of 20 Hz with a moving average of 10 values. It is not a rating for one unaveraged reading. Preserve the averaging condition when assessing dynamic measurements.

No. The connection diagram separates RS422 from paths using USB and Industrial Ethernet adapters. USB, PROFINET or EtherNet/IP require an appropriate interface module and cable. ILR3800-100-IO is a separate IO-Link variant and must not be treated as the base model.
