M8 Y-Adapter — Splits One Line into Two Branches
The TE Connectivity T4081112003-000 is a Y-shaped M8 distributor adapter that converts a single male 3-pin A-coded connector into two female 3-pin A-coded sockets. It is designed for free-hanging inline use, splitting one sensor or actuator line into two branches without adding a separate junction box. The housing is molded from polyamide (PA) nylon, colored blue for quick visual identification on the machine, and the threaded coupling nut secures the male end to the mating cable. Rated IP67 when all three ports are mated with the corresponding M8 connectors, this adapter handles washdown environments, dust, and temporary immersion — typical for packaging machinery, conveyor systems, and outdoor sensor networks. The 60 V / 3 A per circuit rating is standard for M8 signal-level power and 24 V DC sensor loops; the 3 A limit reflects the contact size in the M8 shell, not the nylon housing.
Pinout and Mating Compatibility
The adapter carries a 3-position male pin insert (A-coded) on the input side and two 3-position female socket inserts (also A-coded) on the output legs. All three ports use the standard M8 shell size. The A-coding keyway ensures the adapter mates only with A-coded M8 connectors — it will not accept B-, C-, or D-coded plugs, preventing cross-wiring of different signal types on the same machine. Standard M8 A-coded cordsets with 3 pins mate directly to both the male and female ends.
