Xmost M12 Y-shape female-to-two-male splitter provides a three-way connection for compatible industrial equipment wiring. Its FMM arrangement combines one female connector with two side-by-side male connectors in a compact molded housing.
The catalog wiring diagrams show corresponding numbered contacts connected in parallel across the three interfaces. Both male ports therefore share the circuits connected to the female port.
Each interface uses M12 × 1.0 screw locking. The housing includes a mounting hole for securing the adapter 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 Y-shaped splitter housing with side-by-side male ports.
- 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 hole.
- 20 mm male-port centre distance shown in the dimension drawing.
- Unshielded A-/B-coded versions and a shielded D-coded version.

Applications
Suggested applications for this M12 Y-shape FMM splitter include:
- Machine wiring junctions: Connections where one interface shares corresponding circuits with two branches.
- Compatible field-device wiring: Connections using the selected coding and pin arrangement.
- Modular automation equipment: Detachable connections between compatible equipment sections.
- Side-by-side cable connections: Installations requiring two adjacent male M12 interfaces.
- Secured equipment installations: Junctions where the mounting hole 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, where fitted.
- The same numbered connection continues through the remaining fitted contacts.
The 3-pin wiring diagram identifies contacts 1, 3 and 4. Follow these numbers rather than assuming a consecutive 1–3 arrangement.
The two male ports share corresponding circuits; they are not independently switched channels. Use the wiring diagram matching the selected 3-, 4-, 5- or 8-pin version.
