JST YRS Hand Ratcheting Crimp Tool for SZH Terminals / 3734403

JST YRS-491 Strip Feed Hand Crimping Tool for SZH Crimp Terminals. Importance of a High-Quality Crimp. When a crimping tool is used on a terminal, two crimps take place at the same time. One is the electrical connection between conductor and terminal. The other is the insulation crimp which provides strain relief against vibration and tension. It is important that the electrical connection is gas tight without any voids between the wire strands and the terminal. If there any voids present, then corrosion can occur causing resistance and excessive heat which damages the electrical connection. Using a good quality crimping tool will ensure that a full, gas tight crimp is produced preventing future deterioration of the electrical connection and insulation breakage. JST YRS-491 Strip Feed Hand Crimping Tool – Overview. From JST a durable, reliable and easy to use semi-automatic hand operated crimping tool designed to crimp side feeding open barrel strip terminals onto wire. The strip terminals can be cut to the length desired or simply crimped straight off the reel. This hand tool consists of two handles, a ratchet mechanism, feeding plate, guide and alignment features and precision ground dies. The upper die can be inverted offering two crimping positions for 28 AWG and 26 AWG. Ratchet Mechanism. The ratchet is pre-set to a specific force and remains locked until the handles of the tool are fully closed and the dies are bottomed. The handles cannot be opened until a full crimping cycle is achieved therefore preventing partial crimps. Once the cycle is complete the handles will re-open. The ratchet also enables the operator to repeatedly produce consistent, high-quality crimps. Terminal Guide and Guide Plate. This hand crimping tool features a strip carrier, terminal guide and guide plate which secure and align the terminals in preparation for crimping. Key Features and Benefits. Durable and easy to use Precision ground dies Ratchet mechanism ensures full crimp cycle is achieved Guides and carriers for accurate positioning of strip terminals. Questions and Answers.
