Molex 5054322201 Micro-Lock Plus Wiring Harness 1.25mm Cable Assembly

Name: Molex 5054322201 Micro-Lock Plus Wiring Harness 1.25mm Cable Assembly
Brand: Molex
Rating: 5.0 (13 reviews)

This multi-channel precision wiring harness adopts genuine Molex 5054322201 Micro-Lock Plus series 22-position wire-to-board crimp plug with standard 1.25mm single-row pitch, specially customized for compact industrial control mainboards, multi-sensor integrated modules, medical portable monitoring equipment, smart large-size wearable devices and multi-cell lithium BMS multi-channel sampling systems. Micro-Lock Plus features a slim low-profile body with integrated one-piece tactile spring lock and physical anti-misplug ribs, solving the space limitation of large-pitch connectors on dense PCB layouts. Dual crimp gold-plated terminals lock wire core and insulation separately to resist long-term equipment vibration signal loss. The 22Pin full-row layout supports synchronous transmission of multi-group analog/digital sensor signals, multi-cell battery voltage sampling and miniature auxiliary power circuits in one single cable. High-temperature LCP UL94 V-0 flame retardant housing withstands SMT reflow soldering heat shock, fully RoHS compliant with optional halogen-free material. Customizable cable length, AWG wire gauge (26/28/30AWG), wire color sorting, pin mapping and terminal processing are available, widely applied to automated test bench multi-channel signal acquisition, medical multi-parameter monitors, large-capacity lithium pack BMS sampling and desktop multi-axis robot control board interconnection.

Molex 5054322201 connector cable Micro-Lock Plus Wiring Harness 1.25mm Terminal Wire wire-to-board cable

Product Description

The 1.25mm compact moderate pitch balances miniaturization layout and safe creepage clearance, allowing dense 22-channel signal integration without excessive PCB occupation, solving the layout congestion pain point of split multi-small connectors on multi-sensor control boards. The integrated Micro-Lock spring latch delivers obvious tactile click feedback after full insertion, effectively avoiding incomplete mating leading to partial channel signal dropout under workshop and equipment vibration. Gold-nickel double plating contacts suppress fretting corrosion under alternating cold-hot cycling, maintaining ultra-stable low contact resistance for high-precision multi-channel sampling signals. Flexible multi-strand thin wire withstands tens of thousands of reciprocating bending cycles without wire core fracture, adapting to frequent disassembly of test benches and movable medical monitoring equipment. All crimp transition joints are wrapped with high-temperature heat shrink tubing for secondary insulation and strain relief reinforcement, eliminating wire breakage risks at connector roots.

Every finished Micro-Lock harness passes strict factory quality testing before shipment, including multi-channel signal synchronous stability aging test, reciprocating bending fatigue test, terminal pull retention force test and high voltage insulation withstand screening. We supply fixed-length built-in equipment internal jumpers and customized long-distance multi-channel extension cables for industrial automation integrators, medical device manufacturers and large lithium energy storage pack factories.

FAQ

Q1: What is the advantage of Molex 5054322201 22Pin 1.25mm Micro-Lock compared with split small-pin connectors?

A: Single 22Pin full-row integrated design concentrates up to 22 independent signal/power channels in one slim connector, saving PCB space and reducing messy wiring; the unified Micro-Lock spring lock simplifies equipment assembly and maintenance compared with multiple separate small connectors.

Q2: What maximum continuous current can a single 5054322201 terminal carry?

A: Matched with AWG26 multi-strand wire, each pin stably supports 2A continuous DC current, meeting miniature auxiliary power supply and high-precision weak sensor signal transmission demands.

Q3: Will the spring latch loosen under long-term industrial equipment vibration?

A: Integrated elastic Micro-Lock spring latch + dual internal terminal locking lances form double anti-loose structure, passed hundreds of hours of industrial vibration simulation test, no loose contact or partial channel signal interruption failure.

Q4: Can the pin wiring mapping between the plug and free-end terminals be customized non-one-to-one?

A: Fully supported, we can adjust arbitrary cross pin wiring according to customer multi-channel circuit schematics to match special multi-sensor and BMS signal sorting requirements.
