PZ200V-12-16P是XFCN兴飞推出的一款2mm间距双排方针直插排针,属于电子电路中常用的板间连接核心器件。其设计兼顾了紧凑性、通用性与可靠性,广泛适配工业控制、小型电子设备等场景。以下从核心参数、结构设计、电气性能等维度详细说明:
该产品的关键参数清晰定义了其应用边界,核心信息如下:
类别 具体参数 整体规格 双排2×8P(总16Pin)、间距2mm、行距2mm 结构尺寸 方针结构、直插安装;配合针长4mm、塑高2mm、端接针长2.8mm 电气性能 额定电流2A、工作温度-40℃~+105℃ 材质与外观 触头黄铜、塑壳黑色、插件封装(P=2mm)采用方针结构而非圆针,接触面积较圆针提升约30%,可有效降低接触电阻(减少信号衰减);同时方针的平面接触特性使插拔时压力分布更均匀,减少触头磨损与氧化风险,延长产品插拔寿命(理论可达1000次以上)。
2mm间距是电子行业的标准规范,适配绝大多数PCB板的布局设计(如常见的Arduino板、工业控制板),无需额外调整板上通孔位置,降低电路设计成本。
双排2×8P总16Pin的布局下,塑高仅2mm,配合针长4mm、端接针长2.8mm,整体体积小巧,可满足智能穿戴、手持终端等空间受限设备的板间连接需求。
通孔直插设计兼容自动化焊接(波峰焊、回流焊)与手工焊接,端接针长2.8mm可确保焊接时与PCB板通孔充分接触,减少虚焊风险;直插方式无需额外连接器固定,安装效率更高。
额定电流2A,触头采用黄铜材质(导电率≈1.6×10^6 S/m),接触电阻≤20mΩ,可满足多数电子设备的信号传输(如数字信号、模拟信号)及小功率电源供电(≤24V直流)需求。
工作温度覆盖-40℃~+105℃,塑壳采用耐高温工程塑料(如PA66),可适应北方户外低温、车载电子高温等复杂场景,避免因温度变化导致的塑壳变形或触头氧化。
黑色塑壳具备一定的抗紫外线、抗潮湿能力,配合黄铜触头的耐腐蚀性,可在工业环境(如粉尘、湿度≤95%RH)中长期稳定工作,失效率低于0.1%/千小时。
需搭配2mm间距双排方针排母使用,配合针长4mm需确保排母针孔深度≥3.5mm,避免连接过松(接触不良)或过紧(触头磨损)。
建议在排针塑壳一侧加工缺口(或与排母做对应键位),避免安装时引脚错位导致短路(尤其针对16Pin对称布局场景)。
PZ200V-12-16P作为一款性价比突出的标准排针,凭借方针接触稳定性、2mm通用兼容性、宽温适应性,成为电子设备板间连接的优选器件。其设计兼顾了生产便利性与应用可靠性,可满足多数中低端电子设备的连接需求,是工业控制、消费电子领域的成熟选择。

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.
