Mitutoyo 500-205-30 Digimatic Digital Caliper

Technical Overview

Professional 0-300mm digital caliper featuring AOS electromagnetic induction technology, ABSOLUTE scale memory, 0.01mm resolution, and SPC data output.

Key Features

AOS (Advanced Onsite Sensor) electromagnetic induction type encoder resistant to oil, dust, and water.
ABSOLUTE (ABS) scale retains the origin point even after power-off, eliminating the need for repeated zero-setting.
High-contrast LCD display with an enlarged 11.0 mm character height for easy readability.
Hardened stainless steel construction with ground measuring surfaces for long-term precision.
Equipped with statistical process control (SPC) Digimatic data output for real-time quality assurance data collection.
Flat depth gauge bar integrated into the slider body.
Designed without a thumb roller for slide-locking preference.

Industrial Applications

1. Automotive Engine Component Inspection

Used to measure critical engine block dimensions, piston diameters, and cylinder head features up to 300 mm. The 0.01 mm resolution and ±0.03 mm maximum permissible error ensure exact adherence to machining tolerances.

Problem Solved

Overcomes the risk of incorrect measurement readings in greasy environments; the AOS inductive sensor ensures accurate measurements even when the caliper's scale is exposed to residual cutting oil or coolant.

2. Automated Statistical Process Control (SPC) in Metal Stamping

Continuous measurement of stamped metal part widths and depths on the production floor. Operates in conjunction with Mitutoyo's U-WAVE wireless system via the built-in Digimatic data output port.

Problem Solved

Eliminates manual logging errors and reduces inspection cycle times by allowing operators to instantly transmit precise dimensional data directly to a database without risk of transcription mistakes.

3. High-Precision Mold and Die Manufacturing

Measuring deep cavities, step heights, and outer alignment margins in injection mold cores. The flat depth bar and 64 mm long main jaws enable access to narrow cavities and larger physical interfaces.

Problem Solved

Eliminates the time-wasting process of manually resetting the origin (zero point) on power-up; the absolute electrostatic scale stores the zero point and allows immediate measurement, saving time on multi-cavity tool inspects.
