LinkThe Magnescale DK155 is a high-accuracy, long-range digital gauge designed for demanding industrial measurement applications requiring extended travel and robust performance.
As part of the Magnescale DK series, the DK155 combines long stroke capability with stable, high-precision measurement, making it ideal for large-scale measurement tasks, automation systems, and production environments where durability and consistency are essential.
Key features
- 155mm measuring range for large displacement measurement
- 0.5µm resolution for precision measurement applications
- Accuracy of 5µm across full stroke
- Robust construction for harsh industrial environments
- Resistant to oil, dust, vibration, and shock
- Magnetic adsorption type feeler available for stability on large parts
- Built-in reference point for repeatable positioning
- A/B quadrature output for integration with PLCs and control systems


Description
The DK155 is part of the Magnescale DK Series, designed for long-range measurement applications where both durability and measurement stability are critical.
With significantly greater travel than DK10, DK25, DK50, and DK100 models, the DK155 is particularly suited for large component measurement, displacement monitoring, and positioning control.
Its rigid construction ensures consistent measurement performance under mechanical load, while Magnescale’s magnetic detection technology delivers reliable, drift-free measurement even in environments with vibration, contamination, or temperature variations.
