Product Description

This pre-crimped wire-to-board assembly is constructed with complete original matching components from Molex Pico-EZmate Plus 212132 series, all data cross-checked against official catalog:

Receptacle Housing PN: 2121320003, 3-circuit single-row female crimp socket, fixed 1.00mm center pitch
Dedicated Crimp Terminal: Pico-EZmate Plus gold-plated copper alloy crimp contact, exclusively compatible with AWG28 / AWG30 ultra-fine stranded wire
Mating SMT PCB Header: 212134 series unshrouded straight/right-angle surface mount wafer for PCB soldering connection

The black low-halogen PA nylon housing is upgraded with thicker side walls compared to standard Pico-EZmate series, significantly boosting plug withdrawal force to avoid accidental disconnection caused by wire pulling and equipment vibration. Molded physical polarization keys are integrated into the housing to block reverse mating completely, eliminating PCB short-circuit risks during mass assembly production.

Two-point gold-plated contact structure maintains ultra-low stable contact resistance, supporting simultaneous transmission of small power supply and sensor control signals without voltage drop. Matched ultra-thin multi-color electronic wires occupy minimal internal space of slim devices, color coding simplifies circuit identification during assembly.

Every finished harness undergoes strict full inspection before shipment, including continuity test, terminal pull retention force test, 500V AC high voltage withstand test and thermal cycling aging test. We supply single-end finished cables and cross-type dual-connector conversion harness OEM solutions for wearable electronics, medical instruments, smart handheld devices and lithium battery manufacturers.

Advantages

Ultra-compact low-profile design: 1.00mm fine pitch + only 1.20mm mated height, drastically save limited internal space of ultra-thin smart wearables, mini medical devices and compact battery packs.
Reinforced thick housing side walls: Greatly improve plug withdrawal force compared to basic Pico-EZmate version, effectively prevent loose connection under equipment vibration and wire tension.
Physical anti-reverse polarization protection: Molded positioning keys physically block reverse insertion, reduce assembly short-circuit failure rate and lower manufacturer after-sales maintenance cost.
Low-halogen high-temperature flame retardant nylon housing: Stable performance under -45℃ low temperature to 105℃ high temperature, meets strict EU environmental export standards for consumer electronics.
High-current gold-plated dual-point contacts: Up to 2.8A rated capacity in tiny 1mm pitch package, balance miniaturization and power carrying capability for miniature battery power supply circuits.
Flexible full OEM customization support: Arbitrary adjustable cable length, wire thickness and wire color sequence according to customer equipment schematics; small prototype sample orders available for product development verification.

FAQ

Q1: What series, pitch and pin count does Molex 2121320003 belong to?

A: It is part of Molex Pico-EZmate Plus series, 3-position single-row female receptacle housing with fixed 1.00mm center pitch, all specifications sourced from official Molex datasheet.

Q2: What is the maximum continuous current this connector can carry?

A: The series maximum rated current reaches 2.8A for dual-circuit layout, designed for miniature low-power battery and signal circuits, not suitable for high-power heavy load.

Q3: What wire gauges are compatible with 212132 series terminals?

A: Only ultra-fine AWG28 and AWG30 stranded copper wires are supported, matching the ultra-small fine pitch miniaturized design of the connector.

Q4: What is the biggest upgrade of Pico-EZmate Plus compared to standard Pico-EZmate?

A: Thicker housing side walls for stronger plug retention force, low-halogen material option, higher 2.8A current rating and integrated polarization anti-mismate structure.

Q5: Does this wiring harness comply with global export environmental regulations?

A: All raw materials including low-halogen PA housing, gold-plated contacts and electronic wires fully meet RoHS 2.0, REACH SVHC and low-halogen standards; complete material test reports and conformity certificates can be provided for customs clearance.
