MILLIMAR

MILLIMAR is a product line within Mahr's dimensional metrology portfolio, focused on inductive probes, digital comparators, and related signal-conditioning electronics for precision measurement in production and quality-control environments. The line is widely used where sub-micron to low-micron resolution is required on the shop floor, in inspection rooms, and in automated gauging stations. 3G Electric supplies MILLIMAR pencil probes and digital indicators as part of its industrial-equipment catalog, with 42 SKUs currently listed. The range includes plunger-type inductive probes such as the P2004F, P2004MA, P2004TA, and P2010UB, all with 2.5 m cables and accuracy figures of 3 µm or 20 µm depending on model. These probes are intended for dimensional measurement tasks including surface inspection, runout checks, and verification of machined features. The digital indicator side of the line includes the 2000 W, 2000 Wi, 2001 W, and 2001 Wi comparators, which offer a 0.001 mm to 1 mm measuring range, ±0.0007 mm accuracy over that range, inch/metric display switching, and an IP64 protection rating. The non-removable flat back on these indicators supports mounting in fixtures and stands where a stable reference is needed. For technical buyers, the relevant selection criteria are probe accuracy class, cable length, mounting configuration, and display resolution. MILLIMAR probes and indicators are typically integrated with Mahr signal-conditioning units or comparable amplifier systems, and they are used across metalworking, automotive component manufacturing, aerospace machining, and general precision engineering. 3G Electric supports the line with datasheets, SKU-level specifications, and logistics coordination for global delivery. The catalog entries include manufacturer part numbers, accuracy values, cable lengths, and protection ratings so that maintenance managers and procurement specialists can match replacements or specify new gauging setups without ambiguity. Where a probe is listed with a repeatability figure, such as 0.1 for the P2004F, that value is provided alongside the accuracy specification to help assess suitability for a given measurement task. The digital indicators are available in variants with and without inch/metric switching, and the model suffixes indicate the specific configuration. 3G Electric does not manufacture MILLIMAR products; it distributes them as part of a broader industrial-equipment offering that includes burners, pumps, gas controls, and metrology instruments. This means buyers can source MILLIMAR probes and indicators alongside other plant equipment from a single procurement point, with consistent documentation and shipping support. The product data provided for each SKU is intended to be sufficient for cross-referencing against existing Mahr systems, verifying compatibility, and confirming that the accuracy and range meet the requirements of the measurement application. For applications requiring higher or lower accuracy, the catalog includes both 3 µm and 20 µm probe options, allowing users to select the appropriate grade for the feature tolerance being inspected. The IP64 rating on the digital indicators indicates protection against dust and water splashes, which is relevant for environments where coolant or debris may be present. Overall, the MILLIMAR line as supplied by 3G Electric covers the core elements of an inductive gauging system: the probe that contacts the workpiece, the cable that carries the signal, and the digital indicator that displays the measurement. Technical documentation and part-number-level detail are available for each listed SKU.

Frequently asked questions

Common questions about MILLIMAR from 3G Electric.

What is the difference between the MILLIMAR P2004F and P2010UB pencil probes?

The P2004F and P2010UB are both plunger-type inductive pencil probes with 2.5 m cables, but they differ in accuracy class. The P2004F is specified at 3 µm accuracy with a repeatability of 0.1, while the P2010UB is specified at 20 µm accuracy. The choice between them depends on the tolerance of the feature being measured: the 3 µm probe is suited to tighter-tolerance dimensional inspection, while the 20 µm probe may be adequate for less demanding checks or where a larger measuring range is needed. Both are part of the Mahr Millimar series and use the same cable length, so the selection is primarily driven by accuracy requirement and compatibility with the signal-conditioning unit.

What is the measuring range and accuracy of the MILLIMAR 2000 W digital indicator?

The MILLIMAR 2000 W digital comparator has a measuring range of 0.001 mm to 1 mm (0.0000390625 in to 0.04 in) and an accuracy of ±0.0007 mm over that 1 mm range. It features inch/metric display switching and an IP64 protection rating. The non-removable flat back allows it to be mounted in fixtures or stands. This indicator is part of a family that includes the 2000 Wi, 2001 W, and 2001 Wi, which share the same range and accuracy but differ in configuration details such as display units or mounting. For replacement or new installations, verify the model suffix against the existing setup to ensure compatibility.

Are MILLIMAR pencil probes compatible with any Mahr amplifier or do they require a specific model?

MILLIMAR inductive probes are designed to work with Mahr signal-conditioning electronics, typically the Millimar series amplifiers and comparators. Compatibility depends on the probe connector type and the input specifications of the amplifier. The probes listed by 3G Electric, such as the P2004F, P2004MA, P2004TA, and P2010UB, use a standard Mahr inductive probe interface. When selecting a replacement probe, confirm the connector and electrical characteristics match the existing amplifier. Datasheets for each SKU provide the necessary details. If you are building a new system, the digital indicators like the 2000 W can be paired with these probes to form a complete measurement chain.

What does the IP64 rating on MILLIMAR digital indicators mean for shop-floor use?

IP64 indicates that the enclosure is protected against dust ingress and water splashes from any direction. For shop-floor use, this means the indicator can be used in environments where coolant mist, metal chips, or occasional splashes are present, provided it is not submerged. It is not intended for washdown areas or continuous exposure to liquids. The non-removable flat back and the sealed construction help maintain measurement stability in typical machining and inspection areas. When installing, ensure the cable entry and mounting surfaces are not damaged, as the IP rating depends on the integrity of the seals and housing.

Can MILLIMAR pencil probes be used for runout measurement on rotating parts?

Yes, plunger-type pencil probes such as the P2004F and P2004MA are commonly used for runout and concentricity checks on rotating parts. The probe tip contacts the surface, and the inductive sensor converts displacement into an electrical signal that the amplifier or digital indicator displays. For runout measurement, the workpiece is rotated and the total indicated reading (TIR) is observed. The 3 µm accuracy class of these probes is suitable for detecting small deviations. The 2.5 m cable allows the probe to be positioned at the measurement point while the electronics remain in a safe location. Ensure the probe is mounted rigidly and the tip is perpendicular to the surface for accurate results.

What support does 3G Electric provide for MILLIMAR products?

3G Electric supplies MILLIMAR pencil probes and digital indicators with SKU-level documentation, including manufacturer part numbers, accuracy specifications, cable lengths, and protection ratings. The catalog currently lists 42 SKUs. For technical buyers, this means you can cross-reference existing Mahr part numbers, verify compatibility with your signal-conditioning equipment, and confirm that the accuracy and range meet your measurement requirements. 3G Electric coordinates logistics for global delivery and can provide datasheets for each listed product. The company does not manufacture MILLIMAR products; it distributes them as part of a broader industrial-equipment offering that includes burners, pumps, and gas controls, allowing consolidated procurement from a single source.
