1.25mm Pitch Right Angle SMT Wafer Connector with Tin Plating for Wire-to-Board PCB Applications

• Right-angle 90° orientation, side-entry mating, saves vertical PCB clearance height
• Gull-wing SMT terminals + dual hold-down solder nails: resist shifting under vibration & reflow heat
• Polarization key built-in to eliminate reverse insertion damage to pins & harness
• High-temperature resistant insulator withstands standard SMT reflow profile
• Standard 1.25mm pitch, strictly controlled pin position tolerance for consistent mating performance
• Tape & reel packing supports full automatic SMT assembly; no manual through-hole soldering required
• Plating options: standard tin over nickel; gold flash for high-cycle / anti-oxidation requirement
• RoHS compliant, halogen-free option available upon request

1. PCB Anti-shift design: Dual hold-down solder nails, avoid floating / offset during high-volume SMT reflow; many competitors omit full hold-down structure for cost-down.
2. Strict pin co-planarity control: Reduce intermittent contact risk after soldering, critical for compact IoT / wearable devices.
3. Clear polarization geometry: Physical key prevents reverse plug-in; avoids field-return failure caused by human assembly error.
4. Flexible plating solution: Standard tin for cost-sensitive mass production; gold flash for high-vibration / high-humidity working environment.
5. Stable supply for 2-10Pin mainstream positions: Ready stock for common pin counts; support short-lead-time volume order; functional cross-reference to famous brand 1.25mm wafer series without long OEM lead-time.
6. Document support: Provide 2D drawing, PCB footprint suggestion, test report for engineer evaluation & BOM review.

• Consumer Electronics: Small household appliances, smart home sensors, wearable devices
• IoT & Smart Module: Wireless sensor modules, gateway auxiliary signal connections
• Medical Portable Devices: Low-signal internal wiring for portable medical equipment
• Industrial Control: Small PLC auxiliary IO, sensor internal interconnection
• Lighting & Display: LED driver module, small LCD auxiliary signal wiring
• Office Equipment: Compact printer, scanner internal wire-to-PCB connection

1. Confirm pin count: select 2-4-6-8-10Pin according to your signal / power channel quantity.
2. Confirm mounting: This model is Right-Angle SMT, not vertical TH or vertical SMT header. Check enclosure height clearance before PCB layout.
3. Plating choice:
   • Tin over nickel: General indoor static application, cost-optimized.
   • Gold flash: For high-humidity, vibration environment, frequent mating cycles.
4. Wire matching: Match with our supporting crimp terminal & housing; mixing different brand terminals may cause bad contact.
5. SMT process: Must follow recommended reflow temperature profile; prolonged over-temperature will damage plastic housing.
6. Compliance: Notify us if you need halogen-free or special certification documents for end-product CE / UL submission.
7. Sample evaluation: Request engineering samples before mass BOM adoption to verify mating & PCB fit.

Samples are to be sent to our customers for free on their request so long as they are willing to pay for the freight, or we can pay the freight for some old customers from our side as well, or the customer can pay the freight in advance and we can ship samples with our courier as well.
