Specific Function Tool: The YFP-04B is a manual ratcheting crimping tool designed specifically for crimping non-insulated, open-barrel electrical terminals and receptacles. Wire Range and Mechanism: It is compatible with wire sizes from AWG 20 to AWG 10 (0.5-6mm²). The tool features a ratcheting mechanism that is intended to ensure a complete crimp cycle is performed before releasing. Construction and Design: This crimper is constructed from carbon steel. It has a straight handle design and a European-style pliers form factor, which is typically compact for handheld use. Intended Use and Application: This type of crimper is used to create secure, gas-tight connections on bare metal terminals. It is commonly employed in automotive wiring, control panel assembly, appliance repair, and other electrical work requiring reliable terminal connections. Operation and Result: The tool is operated by manual hand pressure. The ratcheting action aims to apply consistent force to form the terminal barrel around the stripped wire conductor, creating a mechanical and electrical bond., Manufacturer: LPAYBCFO
