Detailed LDR20K1 Specifications

The technical material below is retained for this model only. Do not transfer a range, pulse, interface, mechanical or safety value from another 1064 nm product.

Specifications

The tables below retain the supplied model record except for entries explicitly withheld after a comparison with the current model PDF. A value, option or condition from another model is not interchangeable. General explanations are separated from model-specific entries.

Source-review note

The old range and code-accuracy summary contains unsupported qualifiers. The current document also has a TTL/RS422 interface-title inconsistency; those terms must not be treated as interchangeable. The old outline image with malformed annotation is withdrawn.
