In lifting platforms and automated dock systems, precise height detection is essential for operator safety and mechanical synchronization. The MRA-G130-105D3 accurately measures the lift travel distance by translating vertical motion into encoder signals. Its spring-driven tension prevents slack and maintains constant wire pressure, avoiding uneven lift movement. The corrosion-resistant steel wire ensures dependable readings even in dusty or humid conditions, resulting in smoother platform stops and reduced stress on hydraulic components.
When a mobile crane’s boom extends or retracts, maintaining positional awareness is vital for balance and load safety. The MRA-G130-105D3 offers a compact, retractable solution that fits easily within the boom structure, measuring extension lengths up to 5 meters. Its vibration-resistant housing withstands outdoor and mobile conditions, while its linear accuracy enables consistent feedback for stability control. This ensures that the crane’s automation system always knows the exact boom position, enhancing operational precision and safety on site.
In modern warehouse automation, conveyor or stacker units must align precisely for pick-and-place operations. The MRA-G130-105D3 can track linear movement along travel rails with minimal installation space. The spring-loaded wire mechanism adapts to motion without signal drift, while its high repeatability ensures that each stop position remains accurate. By improving travel measurement reliability, it supports faster cycles, better inventory placement, and reduced downtime in logistics operations.
In forming presses and automated hydraulic systems, precise stroke feedback determines product consistency and tool protection. The MRA-G130-105D3 monitors cylinder travel, providing continuous feedback through encoder rotation. Its fine reproducibility and stable tension system prevent measurement errors from vibration or fluid pressure variation. The durable wire and compact build allow integration even in oily or high-temperature conditions, enabling accurate stroke control, reduced scrap rates, and improved overall press efficiency.
