4/8 indent crimping tools

4/8-indent crimping tools serve the crimping of ferrules, pin contacts, and round contacts in pin or socket form for electronic, aerospace, telecommunications, and industrial assembly. The 4- or 8-indent mechanism applies uniform pressure around the contact circumference, ensuring precision when terminating connectors. This product range comprises three main lines: MicroCrimp with 0.01 mm adjustment increments, DigiCrimp with digital display of settings, and SelectorCrimp compliant with AS39029 and EN3155 for the aerospace industry. Forced-lock mechanisms on many models ensure the operation completes only when the required force is reached. Specialized models such as 8720 0303 6 serve the assembly of POF fiber-optic connectors with 2.2 mm diameter. Rennsteig.vn is the authorized distributor of the complete Rennsteig – Germany 4/8-indent crimping tool range, with full manufacturer warranty coverage.

4/8-indent crimping tools serve the crimping of ferrules, pin contacts, and round contacts in pin or socket form for electronic, aerospace, telecommunications, and industrial assembly. The 4- or 8-indent mechanism applies uniform pressure around the contact circumference, ensuring high precision when terminating connectors. This product range comprises the MicroCrimp, DigiCrimp, and SelectorCrimp lines, each meeting specific requirements for adjustability, crimp-force control, and technical standard compliance.

The DigiCrimp line integrates a digital display showing settings, supporting quick verification before operation. The SelectorCrimp line complies with AS39029 and EN3155 standards, meeting aerospace industry requirements. Specialized models such as 8720 0303 6 serve the assembly of POF fiber-optic connectors with 2.2 mm diameter. Forced-lock mechanisms on many models ensure the operation completes only when the required force is reached, minimizing errors during crimping.

Classification by adjustability and display

Crimp-size adjustability directly affects precision when terminating contacts. The MicroCrimp line allows adjustment in 0.01 mm increments, suitable when tight control of ferrule or socket closure is required. The DigiCrimp line adds a digital display showing settings, enabling quick verification before actual operation. Both lines integrate forced-lock mechanisms, ensuring the crimping operation completes only when the required force is reached.

Model 8760 0000 6 belongs to the MicroCrimp line, adjusting crimp size in 0.01 mm increments for round-pin ferrules and socket ferrules. Model 8730 0000 6 also belongs to the MicroCrimp line, serving the crimping of turned pin and socket ferrules with the same adjustment capability. Model 8750 0000 6 is designed for turned pin and socket contacts, meeting precision requirements in electronic assembly. The DigiCrimp line includes 8723 0101 61, 8733 0000 61, and 8733 0101 61, all integrating digital adjustment systems and display screens.

Classification by aerospace and industrial standards

The SelectorCrimp line complies with AS39029 and EN3155 standards, meeting aerospace industry requirements. Models in this line serve the assembly of turned pin and socket contacts, ensuring high reliability under harsh operating conditions. The 4/8-indent mechanism applies uniform pressure, minimizing unwanted deformation on contacts.

Model 8752 0000 6 complies with AS39029 and EN3155, serving the termination of pin and socket contacts in the aerospace industry. Model 8738 0000 6 also complies with the same standards, primarily for round pin and socket contacts. Model 8758 0000 6 is a specialized solution for contact assembly in aerospace, ensuring high reliability. Model 8728 0000 6 serves the assembly of turned pin and socket contacts, compliant with AS39029 and EN3155.

Classification by specialized application

Some models are designed for specialized applications, meeting specific technical requirements in fiber-optic or manufacturer-standard connector assembly. Model 8720 0303 6 serves the assembly of POF fiber-optic connectors with 2.2 mm diameter, belonging to the premium 4/8-indent crimping tool line. Model 8782 0009 6 is designed specifically for male and female turned ferrules in the DEUTSCH series by TE Connectivity, meeting precise crimping requirements in industrial connector assembly.

These specialized models typically integrate adjustment mechanisms suited to the standard dimensions of connector manufacturers. Model 8720 0303 6 is optimized for 2.2 mm diameter, ensuring precision when crimping fiber-optic connectors. Model 8782 0009 6 is suited to DEUTSCH ferrules, enabling control of crimp force and closure according to TE Connectivity technical requirements.

Forced-lock mechanism and crimp-force control

The forced-lock mechanism ensures the crimping operation completes only when the required force is reached, minimizing errors due to insufficient pressure. Many models in the range integrate this mechanism, enabling quality control of the crimp directly during operation. The 4/8-indent mechanism applies uniform pressure around the contact circumference, reducing unwanted deformation.

Both the MicroCrimp and DigiCrimp lines integrate forced-lock mechanisms. Models 8760 0000 6, 8730 0000 6, and 8750 0000 6 belong to the MicroCrimp line, ensuring the crimping operation completes when sufficient force is reached. The DigiCrimp line such as 8723 0101 61, 8733 0000 61, and 8733 0101 61 also integrate similar mechanisms, combined with digital display of settings.

Selection by technical requirements

When selecting, it is necessary to identify the contact type, precision requirements, and compliance standards. If crimp-size adjustment in small increments is required, the MicroCrimp or DigiCrimp line is suitable. If compliance with aerospace standards AS39029 and EN3155 is required, the SelectorCrimp line meets the requirements. If assembling specialized connectors such as POF fiber-optic or DEUTSCH ferrules, the corresponding specialized model must be selected.

The MicroCrimp line includes 8760 0000 6, 8730 0000 6, 8750 0000 6, 8730 0101 61, 8750 0000 61, 8750 0401 61, 8760 0000 61, and 8760 0401 61.
