Details
M12-A3 Over-molded Circular Connector, 3‑pin A‑code, IP67 rated. Features integrated over-molding for high strain and bend resistance; ideal for field wiring in industrial automation sensors and proximity switches. M5, M8, and M12 circular connectors are industry-standard threaded waterproof aviation plugs with ratings up to IP67 and IP68, widely used for sensor, actuator, I/O, robot, and equipment signal/power connections. Available as pin (male) or socket (female), shielded or unshielded. Supports soldering or crimping terminations, offered as ready-to-use molded assemblies or kits for on-site assembly. Full range of straight and angled configurations. M5 suits compact spaces for signal transmission; M8 is common for proximity and photoelectric switches.
M8 circular connector, M8 over‑molded plug, M8 male/female plug, M8 panel mount socket, M8 PCB socket, M8 solder socket, 3‑pin M8 connector, M8 A/B/D‑code, IEC 61076‑2‑104 connector, IP67 M8 sensor connector. M12 supports signals, power, and industrial Ethernet. Gold-plated pins resist vibration and oil; choose shielded versions for EMI-heavy environments or unshielded for cost savings in standard indoor applications. Compatible with both on-site assembly and mass-produced harnesses.
