Product Description
A compact, reliable 2.54 mm pitch header for wire-to-board interconnections, offered in vertical and right‑angle versions with THT and SMT mounting options. The SH 2.54 header features polarized/keyed mating to prevent mis‑insertion, optional friction‑lock for secure retention, and low‑profile designs suited to dense PCB layouts. It mates with SH series crimp housings and terminals for quick assembly in consumer, appliance, lighting, and industrial control applications.
Key features
- Pitch: 2.54 mm; positions typically 2–20 (others on request)
- Mounting: THT (straight/90°) and SMT (top-entry/right‑angle)
- Polarization/keying; optional locking/friction ramp
- Shrouded and unshrouded variants; low-profile options
- Mates with SH series housings and crimp terminals (AWG 22–28)
- Materials: insulating housing PA66/PA9T, UL94V‑0; contacts copper alloy with tin or selective gold plating
- Electrical (typical for 2.54 mm class; see datasheet): up to 3 A/contact depending on wire gauge; rated voltage per configuration; low contact resistance; high insulation resistance
- Environmental: −25 to +85 °C operating; lead‑free solder compatible (wave/reflow)
- Packaging: tape‑and‑reel for SMT; tube/tray/bag for THT
- Compliance: RoHS and REACH; halogen‑free options; agency approvals on request
- Documentation: 2D drawings, PCB footprints, 3D STEP, recommended reflow profiles available
- Services: custom wire harness assemblies, special pin counts, plating, and color options
Typical applications
- Consumer electronics, home appliances, LED lighting
- Control panels, sensors, modules, power boards
- General PCB interconnects where robust, serviceable wiring is required
