DF61‑Y‑2S‑2.2C belongs to Hirose DF61Y (SnapBee™) series, a compact vertical‑mating wire‑to‑board plug housing, 2‑position (2S), 2.2 mm contact pitch. This finished harness is assembled by crimping terminals into DF61‑Y‑2S‑2.2C female plug housing, for connecting wire harness to matching DF61Y PCB header.
Adopts proprietary V‑shape lock mechanism; achieves vertical insertion‑withdrawal, saves equipment inner space. Even with small size, it can deliver stable low‑voltage power. Mainly for lithium battery packs, small household appliances, medical instruments, industrial control modules internal power interconnection. Custom‑made length, wire gauge, end processing are available. Complies with RoHS‑2.0 and UL safety certification.

Advantages
Unique V‑Lock Vertical Mating Structure
Vertical plug‑in design reduces horizontal operating space; reliable snap‑lock avoids accidental drop‑off under equipment vibration and shock.
Compact Low‑Profile Layout
Small housing footprint, well‑suited for miniaturized device inner power connection, saves PCB layout space.
Stable 3A Power Transmission
Mini‑size but supports up to 3A current, fit for lithium battery, small‑equipment power loop.
High‑Temperature‑Resistant LCP Shell
LCP plastic resists high‑temperature environment inside power‑consuming devices, anti‑deformation and anti‑aging.
Anti‑mis‑mating Polarization Geometry
Physical polarization prevents reverse insertion during manual assembly in mass production.
Full Custom Harness Service
Support arbitrary wire length, different wire AWG, tin‑dipped open ends, extra connectors conversion and label printing.

FAQ
Q1: Is DF61‑Y‑2S‑2.2C compatible with DF61Y PCB header?
A: Yes, it is designed to mate with DF61Y series male PCB headers (SMT or through‑hole version).
Q2: What is maximum working current?
A: Rated 3A for 24AWG wire; if use 26‑28AWG wire, actual working current shall be reduced accordingly.
Q3: Can it be used for battery pack connection?
A: Yes, widely applied in small lithium‑ion battery power connection; please select suitable wire gauge according to actual load current.
Q4: Is this harness waterproof?
A: Standard version is non‑waterproof, for inner equipment application only, not for exposed wet environment.
