HEIDENHAIN METRO Series Length Gauge
Key specifications
- High repeatability
- Very high system accuracy of down to: ±0.2 µm
- Ball-bearing-guided and zero-backlash plunger
- Variant with reduced gauging force
- Very long measuring ranges of up to 100 mm
- Interfaces: 1 VPP, TTL, 11 µAPP
- Incremental length gauge
Models: MT 101K, MT 101M, MT 1271, MT 1281, MT 1287, MT 2571, MT 2581, MT 2587, MT 60K, and MT 60M. The MT 12xx and MT 25xx variants differ in measuring range, signal interface, and plunger actuation; MT 60K/60M and MT 101K/101M are longer-range coupling/motor variants.

Historical MT 1201 / MT 2501 quotes
MT 1201 and MT 2501 are METRO incremental length gauges with 12 mm and 25 mm measuring ranges respectively and 11 microamp peak-to-peak current signals. These historical models must not be confused with the TTL MT 1271/2571 or 1 VPP MT 1281/2581 versions.
