PA2.0mm Connector Wire — 2.0mm Pitch Crimp Housing & Pre-Wired Cable Assembly
PA2.0mm Connector Wires — 2.0mm Pitch Crimp Housing & Pre-Wired Cable Assemblies for RC, Drones & Sensor Modules
The PA2.0mm connector wire series uses the same 2.0mm pitch as JST PH2.0mm but with a distinct housing profile — PA2.0mm connectors are widely used in RC receivers, drone flight controllers, servo extensions, battery balance leads, and compact sensor modules across the Chinese electronics ecosystem. With 26AWG UL1007 wire and tin-plated contacts, PA2.0mm assemblies provide reliable, low-resistance connections in vibration-prone RC and drone applications where secure mating and compact size are both required.

Complete Product Range in This Collection
This collection includes: pre-crimped single-head wire assemblies (one housing + bare wire ends, 10cm, 20cm, 30cm), pre-crimped double-head wire assemblies (housing on both ends, same-direction and reverse-direction), PA2.0mm DIP wafer connectors (straight, 2P–12P), PA2.0mm SMT wafer connectors, and bulk crimp terminal wires without housing for custom harness assembly. All wire assemblies use 26AWG UL1007 insulated copper wire.
PA2.0mm vs JST PH2.0mm — Key Differences
Both PA2.0mm and JST PH2.0mm use a 2.0mm pitch, but they are different connector systems with different housing profiles and are not interchangeable. PA2.0mm housings have a slightly different latch geometry and contact design compared to JST PH series. PA2.0mm is more commonly found in Chinese-manufactured RC equipment, drone accessories, and consumer electronics, while JST PH2.0mm is the international standard used in Adafruit STEMMA, SparkFun, and global sensor modules. Always verify which system your device uses before ordering.
Ideal Applications
- RC receiver and transmitter servo signal wiring
- Drone flight controller peripheral connections (buzzer, LED, GPS)
- LiPo battery balance lead extensions and adapters
- Compact sensor module wiring in Chinese-manufactured electronics
- DIY RC car, boat, and aircraft wiring harnesses
- Consumer electronics internal wiring requiring 2.0mm pitch connectors
PA2.0mm Connector Buying Guide
Step 1 — Verify connector system: Confirm your device uses PA2.0mm and not JST PH2.0mm. The housing latch shape and contact geometry differ. If unsure, order a small quantity first to verify compatibility before bulk ordering.
Step 2 — Choose pin count: PA2.0mm is available from 2P to 12P. For servo signal connections, 3P (signal, power, ground) is standard. For battery balance leads, pin count matches the cell count + 1.
Step 3 — Single vs double head: Single-head assemblies have a housing on one end and bare wire on the other, for soldering to a PCB or connecting to a second housing. Double-head assemblies have housings on both ends for direct plug-in connections.
Step 4 — Cable length: 10cm is standard for compact RC builds. 20–30cm for longer routing paths or extension cables.

PA2.0mm is a specialty pitch that many international distributors do not stock; Yoeruyo maintains consistent inventory for both prototyping and production quantities. Custom cable lengths and configurations available on request.
Frequently Asked Questions
Q: Are PA2.0mm and JST PH2.0mm connectors interchangeable?
A: No. Despite sharing the same 2.0mm pitch, PA2.0mm and JST PH2.0mm have different housing profiles and contact geometries. They will not mate with each other. Always verify which system your device uses before ordering.
Q: What is PA2.0mm used for in RC applications?
A: PA2.0mm is widely used in Chinese-manufactured RC receivers, servo extensions, ESC signal wires, and battery balance leads. It is the de facto standard for many budget and mid-range RC products from Chinese manufacturers.
Q: Can I use PA2.0mm for LiPo battery balance leads?
A: Yes. PA2.0mm is commonly used for LiPo balance leads in Chinese-manufactured battery packs. The pin count equals the number of cells + 1 (e.g., 3P for 2S, 4P for 3S, 5P for 4S).
Q: What wire gauge do PA2.0mm assemblies use?
A: 26AWG UL1007 (0.14mm²), rated 300V. This supports approximately 1–2A continuous current per wire, suitable for signal and low-power connections.
