Molex 51005 / 51006 Connector Kit — 2.0mm Micro-Latch (Micro Losi), 2–10 Pin
The complete wire-to-board solution for the Molex 51005 / 51006 connector system — also known as the Micro Losi or Molex MX 2.0mm in RC and FPV communities. This kit bundles everything you need in one pack: positive-latch receptacle housings (51005), PCB through-hole headers (51006), crimp terminals, and 22AWG pre-crimped cable assemblies in assorted pin counts from 2P to 10P.
No crimping tool required — the included pre-crimped cables plug directly into the housings. Ideal for rapid prototyping, harness repair, RC battery connector replacement, and compact embedded system wiring.
Kit Contents
- 51005 Receptacle Housings — Wire-side female plug with friction/positive latch, 2.0mm pitch, 2–10 circuits

Molex 51005 vs JST PH 2.0mm
Both use 2.0mm pitch but are not directly intermateable. The 51005/51006 uses a friction latch; JST PH uses a positive keyed latch. Do not force-mate. Adapter cables are available to bridge the two systems if needed.
Typical Applications
- 🔋 RC / FPV: 1S and 2S LiPo battery connector replacement for micro RC cars, trucks, and Blade Inductrix-style FPV quads (Micro Losi standard)
- 📡 IoT & Embedded: Battery and sensor connections in wireless sensor nodes, MCU dev boards, and compact embedded systems
- 🏭 Industrial: Signal-level PCB-to-wire connections in compact control panels and DIN-rail modules
- 🏥 Medical / Portable: Low-current sensor harnesses in portable diagnostic and wearable devices
- 🔧 Prototyping: Rapid harness assembly and repair without a crimping tool
