Micro-Lock™ 1.25mm Pitch SMT Wire-to-Board System, Single and Dual Rows, Positive Lock

Molex's 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 making it ideal for tight-packaging applications across all industries.

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-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.

Features and benefits include:

  • Damage-proof pin protection feature that prevents header pins from being bent or crushed, even during angled mating.
  • Compact size and low profile that provides space savings.
  • Low-insertion force with tin plating for easy mating/unmating and that provides a more cost-effective design over gold plating.
  • Wide mating latch with two-point positive lock that provides secure-mating retention, additional mechanical stability and good “click” feeling
  • Low-halogen housing and wire harness material that meets environmental standards.

Applications:

  • Automotive
  • Consumer
  • Data/Communications
