HARTING Circular Connector, 4 Contacts, Cable, M12 Connector, Plug, Male, IP65, IP67, Harax M12 Series

Harting Harax M12 Series Circular Connector, 4A Current, 50V Voltage - 21032811405

This circular connector is a compact, straight cable-mounted M12 plug designed for Ethernet-capable field connections. It provides a shielded, D‑coded Interface with four contacts and is built for use in industrial electrical and automation installations where environmental sealing and temperature resilience are required.

Features & Benefits

• Gold over nickel contacts minimise contact resistance and corrosion
  Rated current 4 A supports moderate power and signal transmission
  Operates from −40°C to 85°C for wide temperature environments
  Cat.5 Class D transmission up to 100 MHz for Fast Ethernet
  IP65 and IP67 protection when mated for wet and dusty conditions
  Zinc die‑cast housing delivers mechanical robustness in harsh sites

**Applications**

• Suitable for Fast Ethernet links in factory automation networks
  Ideal for sensor and actuator cable connections in control cabinets
  Used for fieldbus terminations in machinery and conveyor systems
  Can be used for outdoor instrumentation requiring sealed interfaces
