1.Product Overview
The MTS RHM0050MD531P102 is an advanced magnetostrictive linear displacement transducer engineered for precision motion control in extreme industrial environments. Featuring Temposonics® R-Series technology, it provides absolute position measurement across a 50mm stroke with ±0.03% FS accuracy and zero mechanical wear. Its rugged 316L stainless-steel housing (IP68/IP69K-rated) withstands 500-bar hydraulic pressures, aggressive chemicals, 100g shock loads, and temperatures from -40°C to +125°C. With dual-output capability (±10V analog + IO-Link digital) and SIL 2/PLe compliance, it delivers reliable position feedback for safety-critical systems. The integrated EMC protection ensures stable operation near VFDs and welding equipment, while the compact design enables integration in space-constrained applications.
