The CM21 series is a cable with connectors which

was developed for the Industrial Ethernet.

The CM21 series conforms to IEC61076-2-101

M12 D-Coding standard. It can be used as

an interface for the Industrial Ethernet with

confidence.

The operators can reduce the working process

because it is delivered as over-molded cable

assemblies.

◆ Mating method

Two positioning keys conforming to IEC61076-2-101 M12 D-Coding standard prevents the

operators from having cross plugging problems.

By adopting M12 (1mm pitch) thread for the coupling ring, the smooth mating and dis-mating

are achieved.

◆ Water-proof and dust-proof structure (IP67)

The plug connector has an O-ring which completely prevents water and dust from intruding

inside when the connectors are mated.

◆ Combination of connectors for cable assembly

The cable assembly combined with the CM21 connector and the modular plug can be also

provided in order to be used with the modular jacks of the Ethernet.
