Crimping tool helos TM11/TM21 73001 for Hirose connectors

The helos crimping tool model 73001 is a handheld mechanical crimper designed for use with Hirose connectors and compatible with TM11 and TM21 dies. It delivers controlled mechanical pressing action to form reliable crimps on terminals and contacts used in electronics and telecommunications cable assemblies. The tool is intended for connector installation, cable assembly and repair tasks where Hirose-compatible crimping is required, offering a compact, manually operated solution for workshop and field use.

Advantages

The helos TM11/TM21 73001 crimping tool provides stable, repeatable crimping results through precise mechanical leverage. Its compatibility with both TM11 and TM21 dies makes it versatile for different Hirose contact designs without requiring multiple dedicated tools. The handheld format allows use in confined spaces and for on-site repairs, while the mechanical action requires no external power source, supporting portability and simple maintenance.

Suitable for

• Crimping terminals and contacts for Hirose connectors in cable assemblies
• Field repairs and on-site connector replacement
• Small-scale electronics manufacturing and prototyping
• Telecommunications and data-connection cable termination tasks

Key specifications

• Die compatibility: compatible with TM11 and TM21 crimping dies
• Application: designed for terminals and contacts used with Hirose connectors
• Use environment: workshop and field use; manual operation without external power
• Form factor: compact handheld tool suitable for confined spaces

How to use

Select the appropriate TM11 or TM21 die for the specific Hirose contact, install the die into the tool according to the die manufacturer’s instructions, and position the stripped conductor and terminal in the die cavity. Close the handles with steady pressure until the crimp cycle is complete and the terminal is securely formed. After crimping, inspect the crimp visually and, if required, perform a pull test or electrical continuity check to verify mechanical and electrical integrity. Follow standard safety procedures such as wearing eye protection and keeping fingers clear of the crimp area during operation.

Recommendations

Use the helos 73001 tool only with dies and terminals specified for Hirose contacts; regularly inspect dies and the tool for wear, and calibrate or replace dies when crimp quality degrades. For consistent results, maintain clean contact surfaces, ensure correct conductor strip length, and use the manufacturer-recommended crimp parameters for each terminal type.
