MILLIMAR

MILLIMAR is a brand of precision measurement instruments manufactured by Mahr GmbH, a German company with a history dating back to 1861. The MILLIMAR product line focuses on inductive probes and digital comparators used for dimensional metrology in industrial quality assurance and production environments. These instruments are designed for high-accuracy measurement of displacement, runout, thickness, and geometric tolerances in applications such as machining, automotive assembly, and aerospace manufacturing. The product families available through 3G Electric include pencil probes (plunger and lever types) with cable lengths typically 1.2 m or 2.5 m, and digital indicators with non-removable flat backs. Accuracy specifications range from 3 µm to 20 µm for probes, with digital comparators offering resolution down to 0.001 mm and measurement ranges up to 1 mm. The digital comparator model 2000 W carries an IP64 rating, indicating protection against dust ingress and splashing water, suitable for shop-floor use. All MILLIMAR probes are inductive-type sensors, compatible with Mahr Millimar series amplifiers and evaluation units. 3G Electric stocks over 40 SKUs of MILLIMAR products, providing datasheets and logistics support for global procurement. The brand is recognized for its robust build standards, with probes featuring hardened steel plungers and lever mechanisms designed for repeatable contact with workpieces. The inductive sensing principle offers long-term stability and resistance to environmental factors like oil and coolant, making these instruments suitable for integration into automated inspection systems. For plant engineers and maintenance managers, MILLIMAR products provide a reliable means of verifying part dimensions during production runs or for incoming quality checks. Procurement specialists can source these items through 3G Electric with manufacturer part numbers such as P2004F, EHE-2056, and 2000 W, ensuring compatibility with existing Mahr measurement setups.

Common Applications

  • Automotive engine assembly — MILLIMAR plunger probes (e.g., P2004F) for measuring valve seat concentricity
  • Aerospace component inspection — MILLIMAR lever probes (e.g., EHE-2056) for checking undercut radii in turbine blades
  • Precision machining — MILLIMAR digital comparator 2000 W for in-process thickness verification of machined parts
  • Quality control laboratories — MILLIMAR inductive probes with 3 µm accuracy for dimensional certification of reference standards
  • Hydraulic cylinder manufacturing — MILLIMAR plunger probes (e.g., P2010M) for measuring bore runout during honing operations

Frequently asked questions

Common questions about MILLIMAR from 3G Electric.

What is the difference between plunger and lever type MILLIMAR pencil probes?

Plunger-type probes have a linear contact tip that moves axially along the probe axis, suitable for direct measurement of flat surfaces, depths, and heights. Lever-type probes use a pivoting arm with a contact tip at the end, allowing measurement of hard-to-reach features like grooves, undercuts, or angled surfaces. Both types are available in the MILLIMAR series with inductive sensing and cable lengths of 1.2 m or 2.5 m.

What accuracy levels are available for MILLIMAR inductive probes?

MILLIMAR inductive probes are offered with accuracy specifications of 3 µm, 4 µm, 10 µin (approximately 0.25 µm), and 20 µm, depending on the model. For example, the P2004F and P2004TA models provide 3 µm accuracy, while the P2010M and P2010FB models offer 20 µm accuracy. The lever-type EHE-2056 has 10 µin accuracy. These values are typically stated over the full measurement range.

Are MILLIMAR digital indicators compatible with existing Mahr measurement systems?

Yes, MILLIMAR digital indicators, such as the 2000 W model, are designed as part of the Mahr Millimar series and are compatible with Mahr amplifiers, evaluation units, and data acquisition systems. The indicator features a non-removable flat back for mounting and provides output via cable. It offers inch/metric switching and a measurement range of 0.001 mm to 1 mm with an accuracy of ±0.0007 mm over 1 mm range.

What is the IP rating of MILLIMAR digital comparators, and what does it mean for shop-floor use?

The MILLIMAR digital comparator model 2000 W has an IP64 rating. IP64 means the device is dust-tight (6) and protected against splashing water from any direction (4). This makes it suitable for use in industrial environments where exposure to coolant, oil mist, or light washdowns may occur, though it is not submersible.

Can MILLIMAR pencil probes be used with non-Mahr amplifiers?

MILLIMAR inductive probes are designed for use with Mahr Millimar series amplifiers and evaluation units, which provide the necessary excitation and signal conditioning for the inductive sensor. While some third-party amplifiers may be compatible if they support the same electrical interface and connector type, it is recommended to verify compatibility with the specific probe model and amplifier specifications to ensure accurate measurement.
