Part 1: Purchasing Sourcing FAQs
Q1: What certifications can you provide for M1103 series to meet EU export requirements?
A1: This wire-to-board connector is fully RoHS & REACH compliant. Housing adopts PA6 UL94V-0 flame retardant material; we can offer full test reports, material certificates, MSDS and customs HS code 8536909000 documents for European customs clearance.
Q2: What’s your standard lead time for mass OEM bulk orders of M1103M-1x2 & M1103H-1x2?
A2: Regular stock items ship within 3–7 working days; mass production orders above 10k pcs take 15–20 working days. We own full injection & stamping workshops to guarantee stable delivery without third-party outsourcing delays.
Q3: Can we get free engineering samples for project validation? Any sample cost & freight policy?
A3: We provide small free samples for OEM project qualification; customers only cover international freight. We support sending samples to Europe, Southeast Asia and other global regions for laboratory testing.
Part 2: Engineering R&D / Application FAQs
Q1: What wire AWG sizes does M1103 wire housing support? What’s the OD range for each silicone seal plug?
A1: Three seal options available: A for AWG6# (OD8.00~8.60mm), B for AWG8# (OD5.90~6.80mm), C for AWG10# (OD3.80~4.60mm). Choose matched seal to guarantee IPX7 waterproof performance.
Q2: What’s the maximum electrical rating of this 2Pin wire-to-board connector? Can it run full 80A continuously under high temperature?
A2: Rated 80A AC/DC max, 600V AC/DC, withstand voltage 2200V AC/min. For long-term operation above 100°C ambient temperature, we recommend derating current by 20% to avoid overheating.
Q3: Does this series have built-in TPA anti-retention structure without extra separate snap buckles? How does it prevent terminal retreat under vibration?
A3: It adopts integrated internal molded TPA locking ribs inside housing, no additional external buckle required. The inner barbs lock crimp terminals tightly to stop backward sliding under continuous vibration of EV, pump and drone equipment, reducing intermittent circuit failure.
Q4: What operating temperature range can the connector withstand? Is the housing material resistant to aging for outdoor long-term use?
A4: Operating temperature: -40°C ~ +125°C. PA6 UL94V-0 flame retardant plastic features good heat aging resistance, suitable for outdoor energy storage, vehicle and HVAC all-weather deployment.
Q5: What’s the plating material of terminals? How about corrosion resistance for humid coastal or rainy outdoor environments?
A5: Terminals are copper alloy with tin plating. Tin plating delivers stable conductivity and basic anti-corrosion performance; for high-salt coastal projects, we can customize gold-plated terminals upon request.
Q6: What PCB layout do I need for M1103H-1x2 header? Can you provide PCB footprint drawing and 3D STEP files for design reference?
A6: We can supply official dimension drawing, PCB footprint library and 3D model files free of charge. The PCB header is vertical board-mount design, easy for layout on power boards of energy storage and EV control units.
