Technical description and application scope
Application and selection
Leuze AMS 138i 40 BTA, article 50155770, is a laser position measurement system. Selected exact-model data: measuring range: 100–40000 mm; resolution: 0.001–10 mm, adjustable; accuracy: ±2 mm.
Resolution, accuracy and update time describe different aspects of a measurement. The smallest reported increment is not a complete accuracy specification. Consider the target or reflector arrangement, measurement axis and controller update cycle together. A shared communication interface does not by itself establish mechanical or functional interchangeability.

Engineering integration
Use article number 50155770 together with the complete designation AMS 138i 40 BTA when selecting a replacement, checking a quotation or requesting technical support. Compare the actual installation space, power supply and controller requirements before purchase. A matching housing or a similar model suffix does not prove interchangeability.
Before commissioning, define an acceptance test with representative operating conditions. Record the configuration, reference samples and controller response. Repeat the relevant test after mechanical adjustment, wiring changes or replacement. Safety devices require validation of the complete protective function by competent personnel; ordinary sensing devices must not be assigned an unverified protective function.
