Phoenix Contact(菲尼克斯)1803303为工业级插拔式接线端子,属于板端/插座-闭口类型,核心结构为1排5针(1×5P),针脚间距3.81mm,外壳采用绿色绝缘材料,安装方式为弯针焊接,总PIN数5P,单排针脚数5P。该产品专为PCB板与外部电路的快速可靠连接设计,是菲尼克斯工业连接体系中的经典紧凑型端子之一。
1803303的核心电气与环境参数符合工业设备的严苛要求:
该端子针对工业场景的可靠性与易用性优化,关键设计亮点包括:
插座采用封闭结构,可有效阻挡灰尘、油污、金属碎屑等异物进入,避免接触件氧化或短路,提升长期使用的可靠性,尤其适合粉尘较多的工厂车间、户外机柜等环境。
弯针设计(90°针脚)可实现PCB板的垂直/侧面安装,节省设备内部空间,适配紧凑布局的工业控制板(如PLC模块、伺服驱动器)。针脚采用镀锡处理,焊接性优异,减少虚焊风险。
3.81mm是工业接线端子的通用间距之一,与菲尼克斯同系列插头(如MC 1.5/5-G-3.81)完全兼容,同时可适配第三方同间距插头,降低系统集成成本。
绿色外壳不仅便于设备内部的颜色编码管理(如区分电源、信号回路),还采用阻燃等级UL94 V-0的聚酰胺材料,防火性能优异,符合工业设备的安全规范。
无需专用工具即可实现插头与插座的快速插拔,插拔次数可达500次以上,便于设备调试、维护或模块更换,提升现场工作效率。
1803303因紧凑结构与高可靠性,广泛应用于以下工业领域:
为确保端子性能与设备安全,使用时需注意:
作为菲尼克斯的核心工业端子产品,1803303依托品牌优势具备以下核心竞争力:
综上,Phoenix Contact 1803303是一款兼顾紧凑性、可靠性与易用性的工业级插拔式端子,可满足多数低压工业设备的连接需求,是工业自动化、电力电子等领域的优选组件。
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.
