S3TL Series Ferrule and Crimping Tool Line


The S3TL Series is a ferrule and crimping tool product line of ferrules, wire strippers, crimpers, and screwdrivers.  The series includes various sizes accommodating wire gauges from AWG 26 to AWG 8, each with one or two wires, depending on part number. Each ferrule incorporates an electrically insulated cover, which is color-coded using the German Weidmüller standard, for easy recognition by installers. The ferrules are UL 486F certified when used together with S3TL series crimping tools.


For optimal and efficient installation, IDEC offers two wire strippers, three crimping tools, and three insulated screwdrivers. The strippers and crimpers are ergonomically designed for comfortable function with minimal required force. Crimping tools include a ratchet function that does not release until the connection is fully completed, ensuring work quality by eliminating errors and avoiding crimp faults. Screwdrivers are IEC60900:2004 and VDE certified with insulation of up to 1000V AC and 1500V DC, providing safe user protection against electrical shock.
