MSA 373, MSA 374, MSA 375 Technical data

(MSA 373) • mounting of the encoder head optional via spring rod or coupling bar • free positionable swichting magnets for special functions • distance coded reference marks (K) • for application on presses, bending machines, hydraulic cylinders• large cross-section, enclosed version, rigid mounting • roller bearing dual guided scanning carriage • easy mounting as a result of large mounting tolerances • mounting of the scale via holes on the extrusion ends, additional mounting brackets for "90° mounting"
