Name: Molex 5040510401 Picolock 4P Connector Cable 1.5mm Crimp Terminal Wire
Brand: Molex
Rating: 5.0 (53 reviews)

This compact finished wire harness adopts authentic Molex 5040510401 Pico-Lock series 4-position wire-to-board crimp plug with 1.5mm fixed single-row pitch, paired with flexible ultra-thin multi-strand PVC electronic wire. It is designed for low-voltage signal transmission and miniature auxiliary power circuits of slim lithium battery packs, wearable smart electronics, portable medical instruments, small IoT sensors and mini industrial control modules. The Pico-Lock family features an integrated one-piece elastic spring latch for reliable anti-vibration locking, plus molded physical anti-reverse polarization ribs to eliminate reverse plug short-circuit risks during mass assembly. Dual crimp nickel-gold plated phosphor bronze terminals separately lock wire core and insulation jacket to avoid wire pull-out after long-term vibration. High-temperature LCP UL94 V-0 flame retardant housing fits SMT PCB reflow production processes. The product fully meets RoHS standards, with optional halogen-free material versions. Customizable cable length, wire gauge (AWG26~AWG32), wire color sequence, pin mapping and terminal processing are available, widely used for wearable device battery power lines, sensor signal jumpers, mini drive board internal interconnection and portable monitoring equipment sampling cables.

Molex 5040510401 connector cable Pico-Lock wiring harness 1.5mm terminal wire Lithium Battery Connection Cable battery signal cable ultra-flexible sensor jumper harness

Product Description

The 1.5mm moderate ultra-compact pitch balances miniaturization layout and safe creepage distance, better space efficiency than MOLX Micro Latch 2.0mm connectors while avoiding the ultra-fine 1.0mm Pico-Lock’s low current limitation. The integrated spring latch creates clear tactile feedback after full insertion, effectively preventing incomplete mating which causes intermittent power loss or signal drift inside vibrating lithium battery packs and portable devices. LCP high-temperature housing resists thermal deformation during PCB reflow soldering, suitable for automated mass production of slim electronic products. Ultra-flexible multi-strand thin wire can be freely folded in narrow equipment cavities without scratching lithium battery separator films, lowering internal short-circuit risks of polymer lithium packs. All crimp transition joints are wrapped with heat shrink tubing for strain relief and secondary insulation reinforcement.

Every finished Pico-Lock harness passes strict factory quality inspection before shipment, including continuous signal stability aging test, reciprocating bending fatigue test, terminal pull retention force test and high voltage insulation withstand screening. We supply fixed-length built-in battery short jumpers and customized cross-pin conversion cables for wearable electronics manufacturers, lithium battery pack factories and portable medical equipment R&D teams.

Advantages

1.5mm balanced miniaturization & safety pitch design: Smaller footprint than 2.0mm Micro Latch connectors to save equipment internal stacking space; wider creepage clearance than 1.0mm ultra-fine Pico-Lock to support higher 1.5A single-pin continuous current, compatible with both weak sensor signals and miniature lithium battery power supply loops.
Integrated Pico-Lock one-piece spring self-locking dual safety structure: Molded elastic latch delivers lasting anti-vibration clamping force, paired with physical anti-reverse positioning ribs to completely block reversed insertion; eliminates hidden dangers of battery sampling signal loss and mainboard chip burnout caused by partial plug-in.
Nickel-gold double plating anti-fretting corrosion contacts: Uniform thin gold coating inhibits oxidation and contact resistance rise under long-term alternating cold-hot cycling and equipment vibration, guaranteeing stable lossless transmission of weak battery sampling and sensor signals.
Wide wire gauge compatibility flexible thin wire options: Supports thick AWG26 wire for 1.5A auxiliary power supply and ultra-thin AWG32 wire for ultra-slim wearable lithium packs, multi-strand soft copper core withstands tens of thousands of reciprocating folding without wire core fracture.
4-core multi-function integrated wiring layout: One harness integrates battery positive/negative power, NTC temperature detection and single-channel sampling signal transmission, reduces redundant internal wiring of lithium battery packs and cuts assembly labor costs for electronics manufacturers.
Dual-scenario targeted flexible customization service: Support ultra-short 0.03m built-in battery spot-weld internal jumpers and 5m long-distance equipment extension cables; small-batch prototype sample orders available for new wearable smart devices, portable medical instruments and miniature industrial sensor development verification.

FAQ

Q1: What is the positioning difference between Molex 5040510401 (1.5mm) and 1.0mm Pico-Lock series?

A: 1.5mm pitch provides larger creepage distance and higher 1.5A single-pin current capacity, suitable for miniature lithium battery power supply and medium low-power sensor circuits; the 1.0mm version is only for ultra-thin ultra-low-current pure signal transmission.

Q2: What maximum continuous current can one 5040510401 terminal carry?

A: Matched with AWG26 multi-strand wire, each pin stably supports 1.5A continuous DC current, enough for wearable lithium battery main power and low-power sensor drive circuits.

Q3: Will the spring latch loosen under long-term lithium battery vibration?

A: Integrated elastic Pico-Lock spring latch + dual internal terminal locking lances form double anti-loose protection, passed hundreds of hours of battery vibration simulation test, no loose contact or signal interruption.

Q4: Can the wire end be customized into nickel spot-weld tabs for lithium battery production lines?

A: Fully supported, we can process micro nickel spot-weld lugs at the wire terminal, directly compatible with automatic lithium cell tab spot welding equipment to improve mass production efficiency.
