Fine Pitch 1.27mm Dual Row SMT Male Pin Header Connector Compact PCB Surface Mount Design

Our Fine Pitch 1.27mm Dual Row SMT Male Pin Header Connector Compact PCB Surface Mount Design represents a precision-engineered interconnect solution designed for reliable board-to-board and wire-to-board connections in demanding electronic applications. Manufactured with high-temperature PA6T thermoplastic insulation and precision-stamped brass contacts, this connector series delivers consistent electrical performance across a wide range of operating conditions. Every connector undergoes rigorous quality inspection including contact resistance measurement, insulation resistance testing, and visual inspection under magnification to guarantee conformance to international standards.

The contact system utilizes high-conductivity brass alloy pins with selective gold or tin plating over nickel underplate, providing superior corrosion resistance and reliable mating cycles exceeding industry benchmarks. Our automated assembly lines employ precision insertion technology that ensures consistent pin alignment and coplanarity, critical factors for successful PCB mounting in high-volume production environments. The insulator body is molded from UL94V-0 rated PA6T material reinforced with 30% glass fiber, offering exceptional thermal stability up to 105°C continuous operating temperature while maintaining dimensional accuracy.

• Ultra-Compact Footprint: 1.27mm pitch delivers 50% space savings compared to standard 2.54mm pitch connectors, enabling high-density PCB layouts for miniaturized electronic products
• Precision Micro-Contacts: 0.40mm x 0.40mm square pin cross-section with tight dimensional tolerances ensures reliable mating with corresponding 1.27mm female connectors
• Low-Profile Design: Insulator height of 1.5mm above PCB surface accommodates slim enclosure designs, with optional ultra-low-profile variants available down to 1.0mm
• Signal Integrity Optimized: Reduced pin length and consistent impedance characteristics support high-speed digital signals up to 3Gbps in differential pair configurations
• Industrial Temperature Range: Operates reliably from -55°C to +125°C, making it suitable for aerospace, downhole drilling, and under-hood automotive applications
• Tape-and-Reel Precision: Pocket design with 0.15mm positional accuracy ensures consistent pick-and-place performance at placement speeds exceeding 20,000 CPH

Fine pitch 1.27mm pin headers are essential for next-generation miniaturized electronics including solid-state drive (SSD) module interconnects, wearable health monitoring devices, smartphone camera module test fixtures, and compact FPGA mezzanine cards. The reduced pitch enables high pin-count connections in IoT edge computing modules, portable spectroscopy instruments, and miniaturized drone avionics where every millimeter of PCB real estate is critical. These connectors are also finding increasing adoption in 5G millimeter-wave antenna array calibration interfaces and phased-array radar module interconnects requiring dense, impedance-controlled connections.

Packaged on 178mm or 330mm reels with 16mm wide embossed carrier tape, 500 to 1000 pieces per reel depending on pin count.
