M3 Wireless Connector — Mitutoyo 937387

The M3 Wireless Connector for Mitutoyo 937387 gages is the link between your legacy Mitutoyo Digimatic micrometer and the MobileCollect Wireless measurement collection system. Once connected, measurement data transmits wirelessly from the gage to your SPC software — no manual data entry, no transcription errors, no clipboard in between.

This connector attaches directly to your gage’s round 2×3 Digimatic output and plugs into a Mini Mobile Module EVO (M3E) transmitter — together, they replace the standard Mitutoyo 937387 SPC cable with a compact wireless setup. Each reading transmits wirelessly from the Mini Mobile Module EVO to a MobileCollect Base receiver connected to your PC or data collection workstation.

Legacy Mitutoyo Gage Support

The 937387 round 2×3 connector is found on older-generation Mitutoyo Digimatic micrometers and other legacy instruments. Many shops still rely on these proven gages — and there’s no reason to replace them just to gain wireless data collection capability. This M3 connector brings your existing legacy Mitutoyo instruments into a modern wireless SPC workflow without replacing the gages themselves.

  • All non-IP65 Digimatic Outside Micrometers (Series 293 standard, QuickMike, and others with the round 6-pin connector)
  • Series 568 Borematic Three-Point Internal Micrometers (568-XXX)
  • Series 468 Holtest Three-Point Internal Micrometers (468-2XX, 468-9XX)

Other Versions of This Cable

MicroRidge also offers the 937387 cable/connector for other systems in the MobileCollect and GageWay product families:

DC Connector — Mitutoyo 937387 — For the Command Mobile Module wireless transmitter. Use the Command Mobile Module when you need two-way wireless communication — for example, triggering gage readings across multiple transmitters simultaneously from the MobileCollect Base or your SPC software. This is common on large fixtures or multi-point measurement setups where operators can’t physically press each gage’s data send button.

OEM SPC Cable — Mitutoyo 937387 — 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.

Part of the MobileCollect Wireless Network

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 wireless link, pair it with a Mini Mobile Module EVO transmitter (MC-MM-M3-EVO) and a MobileCollect Base Receiver.

M3 or M3E Connector — Which Version Is This?

This is the M3 variant of this cable. It uses a 2×3, 6-pin connector that plugs into the Mini Mobile Module transmitter.

Transmitter compatibility: This M3 cable is fully compatible with both the current Mini Mobile Module EVO M3E transmitter and the retired M3 transmitter. No adapter, firmware change, or configuration required — it plugs directly into either.

This Cable Supports:

  • Standard SPC measurement output
  • Compatible with Mini Mobile Module M3E transmitter
  • Compatible with Mini Mobile Module M3 transmitter (retired)
  • TriggerSync — on-demand measurement output via M3E transmitter, no manual button press required (launching Q3 2026)

See the Mini Mobile Module EVO Connector Compatibility Guide for photos of all four connector and transmitter combinations, including how M3 and M3E cables seat on each transmitter generation.

This cable supports TriggerSync. TriggerSync is a measurement mode where a reading is triggered from the MobileCollect Base Receiver or directly from your SPC application, without a manual button press at the gage. TriggerSync will enable automated data collection across all of your digital gages. This feature is currently under development and scheduled for release in Q3 2026.
