Heidenhain METRO 2581 ID 363409-02 Measuring length: 25 mm Accuracy grade: 0.2 µm

The METRO series length gauges offer high accuracy over long measuring ranges: with the MT 101 length gauges, measuring ranges of up to 100 mm are attainable at a system accuracy of ±1 µm.

The optimal material mix, optomechanics, and ball-bearing-guided, zero-backlash plunger ensure very high repeatability. The result: very high measured value quality through very low measuring dispersion.

For particularly delicate workpieces, special variants with very low gauging forces of down to 0.01 N are available. Motorized length gauges, such as the MT 60M or the MT 101M, additionally ensure constant gauging forces over the entire measuring range.

• Manually operated with a cable release
• Movement of length gauge relative to tested object
• Movement of tested object relative to length gauge
• Coupling to a moving machine part
• Pneumatic, via compressed air connector on length gauge
• Motorized, via an integrated motor and pushbutton controller
