Overview
The MITUTOYO 21EZA099 Digital Indicator Remote Control Unit is an engineered interface module designed to extend operational flexibility and measurement workflow efficiency in precision dimensional metrology applications. It functions as a dedicated remote trigger and data capture assistant for MITUTOYO’s family of high-accuracy analog and digital dial indicators—including Absolute Digimatic models such as the ID-C1012, ID-S1012, and CD-15DCX series. Unlike generic signal converters, the 21EZA099 maintains native protocol fidelity with MITUTOYO’s proprietary communication architecture, ensuring zero latency in zero-set execution, data hold activation, and unit conversion (mm/inch) commands. Its primary role is to decouple manual actuation from indicator readout—enabling hands-free operation during repetitive gaging tasks, fixture-based inspections, or integration into semi-automated inspection stations where physical access to the indicator face is restricted or ergonomically impractical.
Key Features
- Native MITUTOYO protocol support—no third-party configuration required for full command compatibility
- Dual-mode operation: tactile push-button control (for immediate zeroing, hold, and ABS/INC toggle) and programmable remote input via external switch or PLC dry-contact signal
- Integrated LED status indicators for real-time feedback on power, communication link, and active function state
- Compact, lightweight housing (78 × 45 × 22 mm) with non-slip rubberized grip and recessed battery compartment for CR2032 coin cell (typical life: 12 months under normal usage)
- IP54-rated enclosure suitable for shop-floor environments with moderate coolant mist, dust, and incidental splashes
- RS-232C output port (DB9 female) for direct connection to PC-based SPC software, PLCs, or data loggers; optional Bluetooth 4.2 module available via MITUTOYO accessory kit (model BT-IND-ADP)
Sample Compatibility & Compliance
The 21EZA099 is validated exclusively for use with MITUTOYO Digimatic indicators compliant with the company’s standard 5V TTL-level serial interface specification. It is not compatible with non-MITUTOYO indicators or legacy analog dials lacking digital output capability. From a regulatory standpoint, the unit conforms to IEC 61326-1:2013 (EMC requirements for electrical equipment used in measurement, control, and laboratory use) and meets RoHS 2011/65/EU directive compliance for hazardous substances. While not a standalone measuring instrument, its integration supports traceability workflows aligned with ISO/IEC 17025:2017 clause 6.4.10 (control of measurement equipment interfaces), particularly when deployed within GLP or automotive PPAP inspection processes requiring documented operator intervention points.
Software & Data Management
The 21EZA099 does not include embedded firmware or onboard storage; instead, it serves as a transparent command relay between the indicator and host systems. When connected via RS-232C, it transmits raw ASCII-formatted measurement strings (e.g., “+002.345 mm”) directly to MITUTOYO’s MeasurLink® SPC software (v9.0+), Hexagon Metrology PC-DMIS, or custom LabVIEW/Python-based acquisition scripts. All remote commands—including zero reset, data hold, and absolute/incremental mode switching—are transmitted as standardized MITUTOYO SCPI-like control codes (e.g., “*ZER”, “*HLD”, “*ABS”), enabling deterministic scripting for automated inspection sequences. Audit trails generated by host software retain timestamped records of each remote command event, satisfying FDA 21 CFR Part 11 requirements when paired with appropriate electronic signature and system validation protocols.
Applications
- Fixture-mounted bore gauge setups where the indicator is inaccessible during part loading/unloading
- Manual height gage or surface plate inspections requiring simultaneous hand positioning and measurement capture
- Training environments—allowing instructors to demonstrate repeatable zeroing and data capture without handling the indicator directly
- Integration into low-cost automated check fixtures using pneumatic or solenoid-actuated triggers linked to the 21EZA099’s external input terminal
- Quality labs performing ASTM E1155-compliant floor flatness surveys using MITUTOYO’s EC-2000 electronic level and remote-controlled data logging
FAQ
Is the 21EZA099 compatible with MITUTOYO’s newer Bluetooth-enabled indicators (e.g., ID-B series)?
No—the 21EZA099 predates MITUTOYO’s Bluetooth-native indicator platform and lacks BLE stack support. For ID-B series units, use the official MITUTOYO Wireless App or BT-IND-ADP adapter.
Can multiple 21EZA099 units be daisy-chained to control one indicator?
No—each indicator supports only one active remote interface at a time; parallel connections may cause signal contention and undefined behavior.
Does the unit provide power to the connected indicator?
No—it draws power solely from its internal CR2032 battery and does not supply voltage to the indicator; all power must be provided by the indicator’s own source (battery or external supply).
Is calibration required for the 21EZA099 itself?
No—this is a passive control interface with no measurement function; calibration applies only to the connected indicator per ISO 9001 and ISO/IEC 17025 requirements.
What is the maximum cable length supported for RS-232C communication?
Up to 15 meters using shielded twisted-pair cable (AWG24) with proper grounding; longer runs require RS-232 repeaters or conversion to RS-485.
