Model SN58B automatic ratcheting crimper designed for TE terminals and EPC PCIE / SATA pins. Built to deliver consistent, repeatable crimps on smallgauge wires with a wire capacity of 0.25–1.5 mm². Key benefits Reliable crimps every time: the automatic ratcheting mechanism ensures the tool completes the crimp cycle before release, reducing under or overcrimped connections. Saves time and reduces rework: quick, repeatable crimps speed up assembly and work compared with manual squeezing or improvised tools. Designed for compatible connector types: made specifically to work with TE terminals and EPC PCIE and SATA pins, so you don't need multiple specialized tools. Main attributes Model: SN58B Function: Crimping plier for terminal pins Compatibility: TE terminals and EPC PCIE / SATA pins Wire size range: 0.25–1.5 mm² Mechanism: Automatic ratcheting crimper for controlled, repeatable crimps What this tool does for you Produces uniform mechanical and electrical contacts for lowvoltage signal and power lines in computing and electronics assemblies. Reduces connector failures caused by inconsistent crimps, improving reliability of cable assemblies. Simplifies workshop and field work by combining suitability for multiple common connector types in one compact tool. Typical applications PC builders and technicians: crimping PCIE and SATA power pins when making or repairing internal computer power cables and extensions. Electronics assembly and maintenance: installing or replacing TE terminals on small wiring harnesses used in routers, consumer electronics, and industrial control panels. Prototyping and smallbatch manufacturing: quick, consistent crimps for lowcurrent wiring where precision and repeatability matter. How to use (concise) Strip the wire to the appropriate length for the terminal pin. Insert the pin into the crimp die and position the wire in the crimp area. Squeeze the handles; the ratchet mechanism will complete the crimp cycle and release only after proper compression is achieved. Inspect the crimped assembly for secure mechanical hold and proper conductor insertion. Performance and care The ratcheting action provides consistent pressure through the entire crimp. Visual inspection and a light pull test ensure correct installation. Keep the tool clean and of debris; store in a dry place to preserve function. Periodically check for wear on the crimping profiles when used regularly in production settings. Why choose this tool Purposebuilt for TE and EPC PCIE/SATA pins with a practical wire range of 0.25–1.5 mm². Automatic ratcheting ensures consistent results and reduces operator variability. Useful for technicians, assemblers, and hobbyists who need a reliable, repeatable crimp tool for small connector pins.
