x b o m
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 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.

“Crash-Free” Mating
Two-Point Latch Design
With Good “Click” Feeling
And Locking Force
Guard wall and slits molded into the housing and header (above
left) help to provide mating alignment. 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.
