Circular connectors for hydrogen applications

As one of the largest manufacturers of industrial connection technology, HARTING has a comprehensive portfolio of connectors in all common sizes and codings.

The product range includes circular connectors, overmoulded cable assemblies as well as PCB connectors and panel feed throughs that can be assembled on-site.

Electrical connections through connectors are safely protected from external influences.

Even with vibrations and movements, which are common in industry and traffic engineering, the stable connection achieved with round connectors is impressive.

Various connection types are available, which have their benefits depending on the type and use of the connector.

Connectors that can be assembled on-site can be crimped without tools or with special crimping pliers.

The connectors have plastic or metal housings.

The transition from the housing to the cable is made via cable gland, crimp flange or overmoulding.

Connectors guide with all variants

Introduction

The Circular connectors are available in large number of variants for Device side, Cable side and also for Tools. For details see circular connector guide – click here.
HARTING has circular connectors with metric thread (M) as well as thread sizes in inches.
In particular they have M8, M12, M23, 7/8“ series.
The size and mating faces of circular connectors generally correspond to standardized thread sizes.
In addition to the desired or available attachment size, these also result from the physical performance data such as the number and cross-section of the wires and the current carrying capacity.
The mating faces of connectors are coded to prevent mismating.
The coding is incorporated into the inner shape of the insulation bodies.

Features

Standardized sizes and mating faces provide safety.
Coding prevents mismatching.
Time saving by PushPull locking technology and Screw locking technology.
Tool-free field assembly by HARAX termination technology.
Various connection types are available, which have their benefits depending on the type and use of the connector.
Connectors have plastic or metal housings.
