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 thumb-latch 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-LockMicro-Lock™ 1.25 system is about 75% smaller, and is rated at 1.5A versus 3.0A for Micro-Lock 2.0.

The Micro-LockMicro-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.
