Connector insert, Harting HART 64 poles (09 21 064 3101) — 64-contact rectangular insert

Harting 64-contact rectangular connector insert provides a compact, modular solution for organizing signal and power connections in industrial environments. Designed to fit compatible modular housings and hoods, this 64-pole insert enables panel- or cable-mounted assemblies with a dense contact arrangement that supports straightforward wiring and maintenance. The insert is intended for use where reliable electrical contact, clear contact assignment and secure mechanical retention are required.

Advantages

The connector insert offers a high contact density in a standardized rectangular format, reducing cabinet and panel space requirements while enabling organized cable routing. Its modular compatibility with Harting housings and accessories allows quick assembly and replacement without altering existing wiring layouts. The robust contact arrangement contributes to consistent electrical performance and helps maintain signal integrity in industrial applications.

Suitable for

• Industrial machine control panels and junctions
• Panel-mount and cable-termination assemblies
• Signal distribution and low- to medium-power connections
• Environments requiring modular connector systems for maintenance

Key specifications

• Contact count: 64 poles in a rectangular insert format
• Contact arrangement: dense grid suitable for modular housings
• Application: signal and low- to medium-power wiring
• Mounting options: panel-mounted or cable-mounted when used with appropriate housing
• Compatibility: designed for modular connector systems and corresponding hoods

How to use

Install the insert into a matching Harting modular housing or hood following the housing manufacturer’s mechanical instructions. Terminate wires to the individual contacts according to the chosen contact termination method and wiring diagram, ensuring correct wire stripping length and secure conductor connection. For panel mounting, position the housing and fix it using the specified mounting points; for cable assemblies, secure the hood and strain relief before routing the cable. Verify contact continuity and correct pin assignment after assembly and before energizing the circuit.

Usage recommendations

Use the insert only with compatible Harting housings and mating parts to ensure mechanical fit and electrical performance. Select contact termination methods and conductor sizes that match the intended current and signal requirements. Perform routine inspection of contacts and housings in harsh environments and replace the insert if signs of wear, corrosion, or contact degradation are detected.
