Micro-Lock™ Connectors


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.

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 comes standard in natural color material, with custom versions available in different colors to support certain mating and application requirements.
