Product Description
The EH2.54 SMT connector is a 2.54 mm pitch wire-to-board solution designed for reflow assembly, pairing crimped wire housings with surface-mount board headers. Polarized keying and optional friction-latch/self-lock features prevent mis‑mating and accidental unplugging, making it suited to compact electronics that require reliable, serviceable connections.
Key features
- 2.54 mm pitch for robust, easy routing on standard PCBs
- Polarized housing; friction lock/self‑lock options for secure retention
- Vertical (top entry) and right‑angle (side entry) SMT headers
- Reflow‑capable insulators; pick‑and‑place caps and tape‑and‑reel packaging available
- Complete ecosystem: plug housings, crimp terminals, matching SMT/THT headers, and custom cable harnesses
Typical specifications (values vary by supplier/series)
- Positions: 2–12 pins
- Rated current: up to 3 A per pin (depends on wire gauge and temperature rise)
- Rated voltage: up to 250 V AC/DC
- Contact resistance: ≤20 mΩ (typical)
- Insulation resistance: ≥1000 MΩ (typical)
- Dielectric withstand: 1000–1500 VAC for 1 min (typical)
- Operating temperature: −25 °C to +85 °C
- Mating cycles: ≥50 (typical)
Materials and finishes
- Terminals: phosphor bronze/brass, tin plated (optional selective gold over nickel)
- Wire housings: PA66 or PBT, natural/white standard; optional UL94 V‑0
- SMT headers: high‑temperature LCP/PA9T insulator for lead‑free reflow; matte tin over copper on solder tails
Mating, mounting, and assembly
- Wire side: crimp terminals for AWG28–22 conductors (≈0.08–0.34 mm²); supports manual, semi‑automatic, and automatic crimp tooling
- Board side: SMT headers in vertical or right‑angle; THT versions available for mixed assembly
- SMT process: compatible with lead‑free reflow; packaging options include tape‑and‑reel with pick‑and‑place caps
- Harness service: custom assemblies by pin count, wire gauge, length, labeling, heat‑shrink, and overmold as required
Compliance and documentation
- RoHS and REACH compliant
- Optional UL94 V‑0 flame rating for housings
- Documentation available: 2D drawings, 3D models (STEP), PCB footprints, stencil and reflow guidelines, crimping specifications, and incoming inspection reports
Typical applications
- Consumer electronics, IoT and smart home devices
- LED lighting strips and drivers
- Instrumentation, sensors, and control modules
- Small appliances, battery packs, and low‑voltage motor controllers
