The DC Wireless Connector for Mitutoyo 21EAA194 gages is the hardware link between your Mitutoyo dust and waterproof indicator and the MobileCollect Wireless automated measurement collection system. Unlike the Mini Mobile Module EVO (M3E), the Command Mobile Module enables bi-directional wireless communication — readings are commanded remotely by the MobileCollect Base or your SPC software. No button press, no operator touchpoint at the gage required.
In environments with high dust concentrations or active coolant exposure, sending an operator to the gage to trigger each reading isn’t always practical — and in some cases it’s a safety or contamination control issue. A machinist reaching into a coolant-flooded work envelope, or an operator entering a dust-controlled area mid-cycle, introduces both personnel risk and potential process disruption. The Command Mobile Module eliminates that requirement entirely. Readings are triggered remotely from outside the hazardous area — by your SPC software, a foot switch, or a hand switch at the operator station — while the indicator stays sealed in place doing its job.
With the Command Mobile Module, the read cycle is controlled upstream. Read commands are issued by your SPC software via serial output to the Base Receiver, or triggered by a foot switch, hand switch, or wireless remote switch connected to the Base. The Base transmits the request wirelessly to the Command Mobile Module, which triggers the gage and immediately returns the measurement data — all without any operator action at the gage.
This architecture eliminates the human touchpoint in the measurement loop, directly reducing transcription error risk and supporting tighter SPC control limits. The Base can also request single or multiple readings per command cycle and issue sleep commands to extend battery life — all configurable from your host PC or application.
The 21EAA194 cable is purpose-built for Mitutoyo’s dust and waterproof indicator line. If your measurement workflow takes place in environments with airborne particulates, coolant splash, washdown procedures, or other contamination risks, this connector maintains the environmental protection your indicator was designed for while adding automated wireless data transmission capability. With the Command Mobile Module, readings are triggered remotely — by your SPC software, a foot switch, or a hand switch at the operator station — eliminating the need to send an operator into a contaminated or restricted area to initiate each measurement cycle.
The Command Mobile Module transmitter itself is not IP rated, but we see very few failures in the field in wet or dusty environments. The most common issue over time is that certain cutting fluids and industrial chemicals can cause the cable to become brittle with prolonged exposure.

MicroRidge also offers the 21EAA194 cable/connector for other systems in the MobileCollect and GageWay product families:
M3 Connector — Mitutoyo 21EAA194 — For the Mini Mobile Module EVO (M3E). The M3E is the compact transmitter for applications that only require operator-initiated reads at the gage. One-way wireless communication; smaller form factor than the DC.
OEM SPC Cable — Mitutoyo 21EAA194 — For wired connections to the Digital Remote or GageWay interfaces. The Digital Remote provides two-way communication similar to the Command Mobile Module but over a wired connection — ideal for stationary measurement stations. Also compatible with all GageWay wired gage interfaces.
The Command Mobile Module (DC) supports both automated, remotely commanded reads and manual operator-initiated reads via its built-in read button — so it can do everything the M3E does, plus remote automation. The tradeoff is form factor: the DC is larger than the M3E to accommodate the higher-capacity battery required to sustain remote-triggered read cycles. If your application only requires operator-initiated reads at the gage and a compact transmitter profile is a priority, the Mini Mobile Module EVO (M3E) is the right transmitter for that use case.
MobileCollect is a brand-agnostic measurement collection platform — it doesn’t lock you into a single gage manufacturer. Whether your shop floor runs Mitutoyo calipers alongside Mahr micrometers, Starrett indicators, or Fowler height gages, MobileCollect connects them all into a single wireless SPC data network. This connector is one component in that system. To complete the automated wireless link, pair this connector with a Command Mobile Module transmitter (MC-MM-DC) and a MobileCollect Base Receiver.
