## Description

SOMELINE 2542M hand crimping tool for Molex Mini-Fit Jr and Standard .062" crimp terminals. It can also be used for crimping Dupont 2.54mm and KF2510 connector terminals. 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. 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.Mini-Fit Jr. 4.2 mm plug and receptacle housings are made of UL94V-0 flame-retardant nylon with a secure latch. They are suitable for high-current, high-density wire-to-wire or wire-to-board applications such as consumer electronics, industrial equipment, and automotive electronics. Commonly used in PC Motherboard ATX and CPU EPS power supplies.Kit Configuration:2–16 Circuits Connectors24–16 AWG Pins30–16 AWG CrimperDouble-layer Storage BoxUser Manual

## Features

- RATCHETING CRIMPER: Crimping range covers 30-16 AWG, engineered for Molex Mini-Fit Jr. 4.2 mm, Standard .062" 3.68 mm, Dupont 2.54 mm, and KF2510 terminals. The auto-adjusting ratchet ensures a standardized B-type (F-crimp) profile, applying calibrated force to both conductor and insulation grips to minimize contact resistance
- ELECTRICAL & MATERIAL SPECIFICATIONS: Includes 2-16 Pin 4.2mm pitch housings molded from flame-retardant Nylon 66 (UL 94V-0). Operating Temperature: -40°C to +105°C. Rated Current: 13A max. The 24-16 AWG terminals are manufactured from tin-plated copper/brass with dual locking tangs, offering high oxidation resistance and stable current delivery under mechanical vibration
- INDUSTRY STANDARD CROSS-COMPATIBILITY: Connectors are fully interchangeable with standard Molex Mini-Fit Jr. 4.2 mm (5557/5559/5556/5558) and Amphenol Minitek Pwr 4.2 systems. Designed for strict mating compatibility with existing industry-standard headers for both component replacement and new wire harness builds
- WIDE APPLICATION: Engineered for highly reliable wire-to-wire power delivery, the Mini-Fit Jr. 4.2 mm connectors are widely used in PC Motherboard ATX and CPU EPS power supplies. Additionally, they are ideal for complex multi-circuit wiring in industrial automation (PLC), HVAC control boards, 3D printers, e-bike BMS, automotive electronics, and arcade machine restorations
- ERGONOMIC & BEGINNER-FRIENDLY: Designed for efficiency without fatigue. The non-slip TRP handle provides a comfortable grip for prolonged use. Features a built-in Quick Release Lever that allows you to open the jaws safely if a terminal is misplaced or stuck, making it easy for both DIY hobbyists and professionals to achieve perfect results
