HARTING Circular Connector, 4 Contacts, Cable Mount, M12 Connector, Plug Male, IP65 IP67 Protection, Die Cast 21032811405

HARTING 21032811405 Circular Connector is a high-quality industrial cable-mounted M12 plug providing 4 gold over nickel plated contacts designed for robust Ethernet-capable field connections. This connector supports a current rating of 4 A and a voltage of 50 V, making it suitable for moderate power and signal transmission in electrical and automation installations.

The die cast zinc housing ensures mechanical strength and resilience in harsh industrial environments. It offers IP65 and IP67 protection when mated, safeguarding against moisture, dust, and contaminants for reliable outdoor and factory floor use. The connector operates reliably within a wide temperature range from −40°C to 85°C, accommodating diverse operational conditions.

Designed with Cat.5 Class D D-coded interfaces, it delivers Fast Ethernet communication performance up to 100 MHz. The plug supports impulse voltages up to 1.5 kV and is rated to overvoltage category III, suitable for common transient industrial electrical events. Compatible conductor sizes range from 0.14 mm² to 0.34 mm² (AWG26 - AWG22), with cable diameters between 4.5 mm and 8.8 mm for flexible cable assembly.

This connector is ideal for sensor and actuator cable connections within control cabinets, fieldbus network terminations in machinery and conveyor systems, and any outdoor instrumentation applications requiring sealed and durable interfaces. The robust design also supports at least 100 mating cycles, ensuring operational longevity and repeated use without performance degradation.
