Xmost M12 T-shape female-to-two-male splitter provides a three-way connection for compatible industrial equipment wiring. Its FMM interface arrangement combines one female connector with two male connectors in a compact T-shaped housing.
The catalog wiring diagrams show corresponding numbered contacts connected in parallel across all three interfaces. The two male ports therefore share the circuits connected to the female port.
Each interface uses M12 × 1.0 screw locking. An integrated mounting eye provides a fixing point for securing the splitter to equipment. A- and B-coded versions are unshielded, while the D-coded version is shielded.
Key Features
- One female and two male M12 interfaces.
- Compact T-shaped three-way connector housing.
- Parallel pin-to-pin wiring as shown in the catalog diagrams.
- A-, B- and D-coded configurations.
- 3-, 4-, 5- and 8-pin options, depending on coding.
- M12 × 1.0 screw-locking connections.
- Integrated mounting eye with a Ø4.2 mm hole.
- Unshielded A-/B-coded versions and a shielded D-coded version.

Applications
Suggested applications for this M12 T-shape FMM splitter include:
- Machine wiring junctions: Three-way connections for circuits designed to share corresponding contacts.
- Compatible field-device wiring: Connections using the selected coding and pin arrangement.
- Modular automation equipment: Detachable branch connections between compatible equipment sections.
- Secured cable junctions: Installations where the mounting eye can hold the splitter in position.
Use the splitter where the equipment supports the illustrated parallel wiring. Check the combined load carried by shared contacts. For communication circuits, confirm that the network permits the branch topology.
Wiring Diagram
The catalog diagrams show each numbered female contact connected to the same numbered contact at both male interfaces.
For example:
- Female Pin 1 connects to Pin 1 at both male ports.
- Female Pin 2 connects to Pin 2 at both male ports.
- The same numbered connection continues through the remaining contacts.
The two male ports share corresponding circuits; they are not independently switched channels. Use the wiring diagram matching the 3-, 4-, 5- or 8-pin splitter.
