PZ254V-12-4P是兴飞电子(XFCN)推出的一款2.54mm间距双排方针插件排针,针对小型化设备的多路信号/电源连接需求设计,兼具标准兼容性与可靠性能,广泛适配消费电子、工业控制等领域。以下从核心参数、结构设计、性能优势、应用场景及安装注意事项展开概述。
该产品的核心参数围绕“标准间距+紧凑布局”展开,具体如下:
其定位为小型多路连接的通用型排针,既满足低电流信号传输(如传感器I/O),也可承载小功率电源(如5V/3.3V供电)。
相比圆针,方针采用平面接触结构,接触面积较同直径圆针提升约30%,可有效降低接触电阻(典型值≤20mΩ),减少信号传输损耗,同时降低虚接风险,适合对信号稳定性要求较高的场景。
塑高仅2.5mm,双排布局宽度与单排排针相近,可在有限PCB空间内实现4路并行连接,适配便携式设备(如智能手环、蓝牙耳机)、小型工业模块(如传感器节点)等对体积敏感的产品。
2.54mm间距是电子连接领域的“通用基准”,PZ254V-12-4P可与绝大多数品牌的2.54mm排母、单排/双排针座直接配合,无需额外设计适配结构,降低研发成本。
触头采用H62黄铜(含铜量≥60.5%),导电率达40%IACS以上,确保信号/电源传输低损耗;同时黄铜抗腐蚀性能优于纯铜,可在潮湿、轻度盐雾环境下长期使用(符合GB/T 2423.17盐雾测试基础要求)。
工作温度范围-40℃~+105℃,覆盖:
黑色塑壳采用PA66+GF(玻纤增强尼龙66),抗冲击强度≥80J/m,焊接时可承受260℃以下短期温度(符合回流焊/手工焊常规要求),不易出现塑壳变形、开裂问题。
PZ254V-12-4P的4位双排布局,适合多路并行的低复杂度连接,具体场景包括:
总结:PZ254V-12-4P以“标准间距+方针稳定+紧凑布局”为核心优势,适配多场景小型多路连接需求,是消费电子、工业控制等领域的高性价比选择。
Request for quote
Use the form for single models, category sourcing, and multi-line BOM requirements.
Product sourcing intelligence
WMSIC turns product data, package visuals, BOM context, and sourcing signals into practical RFQ notes for buyers.
Model text, package form, tray or reel details, and visual evidence are reviewed together before RFQ feedback.
BOM lines are compared by package, parameters, quantity, and workable alternatives for cleaner sourcing decisions.
Stock routes, quotation confidence, lead-time notes, and shipment feasibility are checked before sales follow-up.
Buyer sourcing scenarios
Typical RFQ scenarios based on the WMSIC form fields, catalog data, manual review steps, and shipment preparation workflow.
The buyer shares the full part number, package requirement, quantity, destination, and available product photos so the quotation can record the exact version under review.
A multi-line BOM is organized into direct sourcing lines, lines that need package clarification, and lines where alternative-part review is permitted.
The original manufacturer part number, datasheet revision, application, critical limits, and acceptable changes are collected before possible candidates are discussed.
Sample quantity, minimum packing, package format, target date, and courier destination are kept together in one RFQ conversation.
Package photos, model markings, board context, and the quantity needed for repair help focus the sourcing review on the relevant version.
When a suffix or package note is incomplete, the response records the open difference and requests buyer confirmation before procurement proceeds.
Packing format, carton notes, invoice details, courier option, destination, and tracking handoff are coordinated around the confirmed order.
The request connects the previously used model, current demand, package evidence, target timing, and replenishment sourcing route.
