Mitutoyo 543-791B-10 Digital Indicator ID-S with ABSOLUTE sensor, 12.7mm/0.5″ range, 0.001mm resolution, IP42 protection, and long battery life.
The Mitutoyo 543-791B-10 Digital Indicator ID-S is a precision measuring tool designed for reliable and user-friendly operation in industrial environments. Featuring an ABSOLUTE electrostatic capacitance linear encoder, it eliminates the need for repeated origin setting, saving time and ensuring consistent results. With a measurement range of 0.5”/12.7 mm, resolution of 0.001 mm, and a large 9 mm LCD display, it provides both accuracy and excellent readability. Its robust IP42 protection and long battery life make it ideal for continuous use in demanding applications.
The Mitutoyo 543-791B-10 ID-S Digital Indicator combines precision engineering with ease of use. It offers a measuring range of 12.7 mm (0.5”), a fine resolution of 0.001 mm (0.00005”), and repeatability within 0.0001”/0.002 mm. The indicator is lightweight at 140 g, equipped with a carbide ball contact point, and powered by a single SR44 battery providing up to 18,000–20,000 hours of operation. Its LCD display with 9 mm characters ensures excellent visibility, while switchable inch/metric functions, ORIGIN (ABS-Zero) setting, and error alarms provide convenience and reliability in all professional settings.
The Mitutoyo 543-791B-10 is designed for professionals who demand accuracy, durability, and ease of use in measurement. Its ABSOLUTE sensor saves time by remembering zero settings, and the large display enhances productivity by reducing operator error. With seamless inch/metric switching and compatibility with data output systems, it becomes a versatile tool for workshops, laboratories, and production lines. Choosing this model means choosing a blend of Japanese precision and practical usability.
In many measurement tasks, re-zeroing indicators or misreading small displays can cause errors, wasted time, and inconsistent results. The Mitutoyo 543-791B-10 solves these problems with its ABSOLUTE encoder technology, ensuring reliable reference points without re-calibration at power-on. Its large, clear LCD display improves readability, while its long-lasting battery minimizes downtime. For engineers, machinists, and inspectors, this indicator ensures efficiency, accuracy, and confidence in every measurement task.
During machine setup, operators use the ID‑S to zero fixtures, verify tool offsets, and check part height without re‑zeroing between power cycles. The ABSOLUTE encoder preserves origin, cutting setup time and preventing drift. The 0.001 mm resolution and large 9 mm LCD make pass/fail calls quick on the shop floor. With gentle measuring force and fast response, repeat checks on the same reference surface stay consistent across shifts.
On assembly lines, the indicator monitors press‑fit depth, actuator stroke, or stack‑up thickness inside jigs. IP42 protection tolerates light dust and coolant mist, while long battery life supports multi‑shift operation. Inch/metric switching speeds mixed‑drawing environments, and repeatability supports SPC sampling. The clear display reduces reading errors for technicians moving between stations, and data output enables logging trends to catch drift before it becomes rework.
Quality teams measure shims, spacers, and turned parts to confirm supplier tolerances at goods‑in. The carbide contact resists wear during repeated checks, and the ≤1.5 N measuring force helps protect delicate finishes. The ABS‑zero function keeps a stable reference across multiple lots, while the 12.7 mm range covers common small components. Optional data capture accessories allow quick recording of min/max values to document compliance and drive supplier feedback.
In lab setups, engineers validate small displacements—spring deflection, cam profiles, or fixture repeatability. The indicator’s 0.001 mm resolution and smooth response help map movement curves without missed peaks. ABS origin simplifies baseline comparisons over long tests or after power cycling. With data output, teams stream readings to analysis software, correlate displacement with force or temperature, and build traceable reports for design reviews and process capability studies.
