Micro-LockTM 1.25mm Pitch SMT Wire-toBoard System, Single and Dual Rows, Positive Lock Ideal for tight-packaging applications in all industries, the Micro-Lock 1.25mm pitch system offers the smallest overall size and highest current-carrying capability of any similar pitch positive-lock system, while also providing a wide range of mating configurations and superior pin and terminal protection Available in single and dual rows in both straight and right-angle configurations, the system is ideal for any application that requires space savings and mating variation. 504185 Crimp Terminal 504193 Housing, Single Row 504186 Housing, Dual Row 504194 Vertical Header, Single Row 504187 Vertical Header, Dual Row 504195 Right-Angle Header, Single Row 504189 Right -Angle Header, Dual Row The Micro-Lock 1.25mm pitch system offers many of the same features as Molex’s Micro-Lock 2.00mm pitch system. These include an outer thumblatch design with two locking points for ease-of-use and secure contact, and a mating design that protects the pins and terminals while providing low insertion force. Key differences between the two systems are size and current rating. The Micro-Lock 1.25 system is about 75% smaller, and is rated at 1.5A versus 3.0A for Micro-Lock 2.0. The Micro-Lock 1.25mm family is available in 2-16 circuits for single row, and 16-40 circuits for dual row. The system offers low-halogen material not only for connectors, but also in the wire-harness material used. The system comes standard in natural color material, with custom versions available in different colors to support certain mating and application requirements.

This also prevents the housing from crashing into and damaging the pins during mating—even if the housing is forced in at an angle—which can happen in competitive designs. Blade terminals with a pin guard feature (above right) provide further pin protection and stability, especially versus most tuning-fork designs, which are more exposed to damage. Robust thumb-latch design provides easy operation and two points of positive-lock contact for secure mating retention. The design also provides a strong “click” feeling for mating assurance.
