M12 A-Coded 8-Position Female Plug with Screw Termination
The TE Connectivity T4110002081-000 is an M12 A-coded circular connector configured as a free-hanging plug with 8 female sockets. It terminates via screw terminals and secures the mating pair with a threaded coupling nut — the standard fastening method for M12 connectors that resists loosening under vibration in industrial machinery and field-installed equipment. Rated 2 A per contact at 30 V, with gold-plated mating surfaces (3.00 µin gold over nickel), the 8-position count suits sensor/actuator harnesses and I/O blocks where multiple signal or low-power lines share a single circular interface. The IP67 seal — dust-tight and protected against temporary water immersion — makes this plug usable in washdown zones, outdoor enclosures, and factory-floor drop cables where moisture ingress is a concern. The shell is nickel-plated brass; the insert is polyamide (nylon). The backshell is glass-filled PBT.
Coding and Mating Compatibility
The A-coded orientation means this plug mates only with A-coded M12 receptacles — the keying pin position is non-negotiable. An A-coded plug will not physically engage with a B-coded, D-coded, or X-coded receptacle. For an 8-position M12 A-coded interface, the mating half is a standard A-coded M12 panel-mount or cordset receptacle with 8 female or male contacts as required by the circuit design. The threaded coupling nut provides the mechanical retention; no secondary latch is present. The 8-position M12 A-coded pinout follows the IEC 61076-2-101 standard for this shell size. The screw termination accepts the prepared wire directly — no crimp tool needed — which simplifies field termination but means the stripped conductor length and screw torque must be consistent across all 8 positions to avoid intermittent connections under thermal cycling.
