Product Features

1. Side‑entry horizontal mating orientation, ideal for side‑plug‑in mechanical structure requirements
2. Dual‑row 2*8P configuration, 1.27mm pitch, compact footprint to maximize PCB usable area
3. H3.45mm controlled housing height, consistent dimensional tolerance for precise PCB stacking
4. High‑elastic brass contact beams, stable contact resistance against minor vibration & shock
5. Nylon housing UL94V‑0 flame retardant, withstands standard SMT reflow thermal cycle
6. SMT gull‑wing terminals, tape‑and‑reel packing for automated pick‑and‑place manufacturing
7. RoHS‑compliant material; gold‑flash, selective‑gold, tin‑plating options for different reliability grades
8. Polarization notch available upon request to prevent reverse mis‑mating

Product Advantage

1. Side‑entry structural advantage: Solves design constraints where vertical top‑entry headers cannot be installed; horizontal side‑plug‑in fits narrow enclosure inner space.
2. Balanced density & manufacturability: 1.27mm pitch achieves high‑density signal routing, still compatible with standard SMT production lines, no special equipment upgrade needed.
3. Brass contact performance: Good electrical conductivity and spring retention force, maintains stable signal integrity under moderate vibration scenarios.
4. Controlled H3.45mm height: Fixed housing height eliminates stacking height deviation risk for multi‑board stacked modules.
5. Flexible sourcing service: Supports sample trial, pin‑count modification and plating customization; acts as a cost‑effective alternative to international branded equivalents.
6. Production‑ready packaging: Tape‑and‑reel supply directly matches pick‑and‑place workflow, lowers assembly defect rate for mass manufacturing.

Application

• Industrial control modules & embedded single‑board hardware
• IoT edge gateway, sensor interconnection boards
• Portable medical auxiliary detection equipment
• Test & measurement instrument internal interconnect
• Smart wearable, handheld consumer electronics
• Communication auxiliary sub‑boards, JTAG debug interface connection

Customization Options

1. Mating counterpart: Must select 1.27mm pitch dual‑row male pin header; verify mechanical dimension compatibility for side‑entry mating.
2. Application scenario reminder: This connector is optimized for signal‑level transmission, not intended for high‑power current delivery.
3. Plating selection rule: Indoor normal environment → tin plating; vibration‑prone / long‑life requirement → gold‑flash; harsh‑environment device → specify custom gold thickness.
4. Mechanical space check: Confirm horizontal side‑mating clearance inside enclosure to avoid housing collision after assembly.
5. PCB footprint: Strictly apply corresponding side‑entry SMT footprint; improper pad layout will cause soldering shorts or open circuits.
6. Production mode: For mass production, select tape‑and‑reel packing; small‑batch prototypes can choose tube packing.
