M3 Wireless Connector — Mahr Federal

The M3 Wireless Connector for Mahr Federal gages is the link between your Mahr Federal caliper, depth gage, or other Mahr Federal instrument 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 SPC output port and plugs into a Mini Mobile Module EVO (M3E) transmitter — together, they replace a standard wired SPC cable with a compact wireless setup. A built-in data send button lets operators trigger readings at the point of measurement, and each reading transmits wirelessly from the Mini Mobile Module EVO to a MobileCollect Base receiver connected to your PC or data collection workstation.

Two Length Options

This connector is available in two lengths. The 3.5″ length is recommended for Mahr Federal calipers where a shorter cable keeps the module compact and out of the way. The 6.5″ length is recommended for depth gages and other Mahr Federal instruments where additional reach is needed.

Other Versions of This Cable

MicroRidge also offers the 959149 cable/connector for other systems in the MobileCollect and GageWay product families:

DC Connector — Mahr Federal 4102915 — 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 Digimatic Cable — Mahr Federal 4102915 — 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.

OEM SPC RS-232 Cable — Mahr Federal 4102410 — For wired RS-232 connections to WedgeLink, MobileCollect RS-232 Remote, and GageWay Pro via the multifunction serial port or front channels with a Level Converter Cable. Includes a data send button.

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.
