Three-piece set of manual crimping pliers (SN-01BM, SN-48B, SN-2549) featuring a self-adjusting ratchet mechanism, designed for terminating a range of small electrical connectors across different wire gauges Each plier is constructed from alloy steel (e.g., 65#/45# steel) and engineered with precision-machined jaws corresponding to specific terminal families and wire cross-sections (e.g., 0.08-1.5mm²) The integrated ratchet is intended to engage during the crimping cycle, requiring a complete squeeze to release, which aims to apply consistent pressure for each crimp Serves as a dedicated tool system for creating reliable solderless connections in electronics assembly, model building, computer hardware (e.g., internal power pins), and low-voltage control wiring Provides a versatile manual tool solution; achieving a secure electrical connection is entirely dependent on matching the correct plier and jaw to the terminal/wire combination and applying proper technique, Manufacturer: LPAYBCFO
