Knife strip (Messerleiste) Harting 09021647921 with total pole count 64

Harting Messerleiste 09021647921 is a knife strip contact insert configured with a total of 64 poles. Manufactured for use within Harting connector systems, this contact insert is intended to provide reliable electrical connections in modular connector assemblies and panel-mount applications that require a 64-pole arrangement. The design is compatible with mating housings and frames from the same product family and supports typical signal and power contact tasks in industrial and machinery installations.

Advantages

The knife strip offers a compact 64-contact layout that enables dense wiring in limited space. It is produced to Harting quality standards, ensuring consistent contact geometry across all poles and predictable mechanical fit with matching housings. The single-piece insert reduces assembly complexity when configuring multi-pole connectors and supports secure, repeatable electrical connections for signal and low- to medium-current applications.

Suitable for

• Modular rectangular connector assemblies requiring 64 contact points
• Panel-mount connector frames in control cabinets and machinery
• Signal distribution and low- to medium-current power connections
• Industrial applications where compact, repeatable contact arrangements are needed

When it may not be suitable

This knife strip is designed specifically for Harting connector systems and mating housings; it may not be compatible with non-Harting or custom connector bodies. It is intended for signal and low- to medium-current uses—applications requiring high-voltage insulation, very high current capacity, or specialty contact types may require a different insert or connector design. Verify mechanical dimensions and mating interface before use.

Key specifications

• Total pole count: 64
• Contact type: knife strip (blade) style contact insert
• Application: modular connector assemblies and panel-mount installations
• Typical use: signal and low- to medium-current electrical connections
• Form factor: multi-contact insert designed for mating housings and frames in the Harting family

How to use

Install the knife strip into the compatible Harting connector housing or frame following the manufacturer's mounting orientation and retention method. Ensure all contacts are fully seated and aligned with the corresponding mating contacts before applying power. When wiring to the contacts, follow standard electrical practices: de-energize circuits, use appropriate wire sizes and ferrules if required, and secure conductors to prevent strain on the contact insert. After assembly, verify continuity and correct pin mapping.

What to consider before purchase

• Confirm mechanical compatibility with the intended Harting housing or panel frame.
• Verify that 64 poles meet the circuit and wiring requirements for your application.
• Check current and voltage needs to ensure the insert's contact type is appropriate.
• Ensure availability of matching mating connectors or housings from the same product family.

Usage recommendations

Use the knife strip with original Harting housings and frames to maintain proper fit and contact performance. During installation, handle contacts carefully to avoid deformation; perform electrical tests after assembly to confirm correct connections and reliable operation.
