HY2.0mm Wire-to-Wire Connectors – 2.0mm Pitch Locking Housings
HY2.0mm Wire-to-Wire Connectors – 2.0mm Pitch Locking Interconnection System
Yoeruyo's HY2.0mm connector range provides compact, secure wire-to-wire interconnection at the 2.0mm pitch. The HY2.0mm series features a robust positive-latch locking housing with male and female counterparts, precision gold-plated crimp terminals, and a compact form factor suited to portable electronics, battery management systems, LED lighting, RC vehicles, and miniaturized industrial equipment. The HY2.0mm is widely used as a reliable alternative to JST PH and SM series connectors where a wire-to-wire locking connection at 2.0mm pitch is required.

Product Components
- Female housing (plug) – wire-side locking receptacle housing accepting HY2.0mm female crimp terminals; 2 to 10 circuits
- Male housing (receptacle) – wire-side locking housing accepting HY2.0mm male crimp terminals; mates with female housing
- Female crimp terminals – gold-plated copper alloy socket terminals for crimping onto AWG 22–28 wire
- Male crimp terminals – gold-plated copper alloy pin terminals for crimping onto AWG 22–28 wire
- Pre-crimped wire assemblies – custom wire-to-wire assemblies with male and female housings, specified wire length and gauge, for OEM integration
Application Scenarios
- LiPo & Li-ion battery packs – secure wire-to-wire battery connector for portable electronics, RC vehicles, and drone power systems requiring positive latch retention
- LED strip lighting – power and signal connections between LED controllers, drivers, and strip segments in indoor and outdoor lighting systems
- RC vehicles & drones – motor signal wiring, ESC connections, and accessory power wiring in RC cars, boats, aircraft, and multirotor UAVs
- Consumer electronics – internal wire-to-wire connections in portable speakers, smart home devices, and compact appliances
- Robotics & maker projects – sensor connections, actuator wiring, and power distribution in DIY robotics and maker community platforms
- Industrial sensors & instrumentation – compact signal wiring for proximity sensors, encoders, and transducer connections in light industrial equipment
Why Choose Yoeruyo HY2.0mm Connectors
- ✅ Positive-latch retention – audible click confirmation and secure latch prevent accidental disconnection in vibration-prone and portable applications
- ✅ Gold-plated contacts – gold over nickel plating ensures low contact resistance and long-term reliability in high-cycle applications
- ✅ Higher current than JST PH – rated at 3A per contact vs 1A for JST PH, making HY2.0mm suitable for higher-current battery and power applications at the 2.0mm pitch
- ✅ Complete male & female set – both housing polarities available from a single supplier for simplified procurement
- ✅ RoHS & REACH compliant – halogen-free materials meet EU and global environmental standards
Buying Guide
- HY2.0mm vs JST PH2.0mm – HY2.0mm is rated at 3A per contact (vs 1A for JST PH) and features a more robust locking latch; choose HY2.0mm for higher-current battery and power applications where stronger retention is needed
- Circuit count – 2-pin for battery power connections; 3–6 pin for sensor and signal wiring; up to 10 pin for multi-circuit applications
- Wire gauge – HY2.0mm terminals accept AWG 28–22 (0.08–0.33mm²); AWG 24–22 recommended for 3A power circuits
- Male vs female housing – order both male and female housings and terminals as a mating pair; pre-crimped assemblies include both ends
- Pre-crimped assemblies – for battery replacement and OEM integration, pre-crimped HY2.0mm assemblies ensure consistent crimp quality and correct polarity
Frequently Asked Questions
What is the difference between HY2.0mm and JST PH2.0mm?
Both use the 2.0mm pitch but differ in current rating and housing design. HY2.0mm is rated at 3A per contact with a robust positive latch; JST PH is rated at 1A per contact with a lighter friction-fit or standard latch. HY2.0mm and JST PH connectors are not interchangeable — they have different housing geometries.
Is HY2.0mm suitable for LiPo battery connections?
Yes. The HY2.0mm 2-pin connector is widely used as a LiPo battery connector in RC vehicles, drones, and portable electronics. Its 3A per contact rating and positive latch make it more suitable than JST PH for higher-current battery applications.
Do I need both male and female housings?
Yes. HY2.0mm is a wire-to-wire connector — both ends require a housing and crimp terminals. Order male and female housings and terminals in equal quantities, or order pre-crimped wire assemblies that include both ends.
What wire gauge is recommended for 3A circuits?
For circuits drawing up to 3A, use AWG 24–22 (0.20–0.33mm²) wire — the upper end of the HY2.0mm terminal's wire range. This ensures adequate current-carrying capacity and a reliable crimp.
Do you offer pre-crimped wire assemblies?
Yes. Custom HY2.0mm wire-to-wire assemblies with pre-crimped male and female connectors are available in specified wire lengths, gauges, and circuit counts. Contact us for OEM assembly quotations and lead times.
