M12 A-Coded 8-Position Panel Receptacle
The T4133012081-000 is an M12 A-coded 8-position female receptacle from the M12 circular connector family, built for industrial sensor/actuator networks, fieldbus junctions, and IP67-rated panel interfaces. The 8-position layout uses the larger M12-8 shell size — wider than the common 4- or 5-pin M12 — to fit all eight contacts in a single circular insert. Solder cup termination means each wire is hand-soldered to the pin cup, not crimped, which suits low-volume harness builds or field repair where a crimp tool for the specific contact is not on hand. The threaded coupling ring provides the mechanical lock; the A-coding keyway ensures it only mates with an A-coded plug, preventing cross-mating with B- or D-coded M12 connectors on the same panel.
Sealing and Temperature Range
The nickel-plated copper alloy shell and polyamide (PA66) insert handle the thermal cycling without cracking or losing seal compression.
Electrical Ratings and Contact Finish
The gold-plated mating surface on the copper alloy contacts handles repeated mating cycles without oxidation, which matters for field-service connectors that get unmated and reconnected during equipment maintenance. The 30 V ceiling keeps it inside SELV limits for most industrial control circuits.
Mounting and Hardware
The copper alloy shell with nickel finish provides adequate shielding for the signal pairs in an unshielded connector; the spec lists this as unshielded, so it relies on the system ground path through the panel and cable braid for EMI control.
