794274-1 产品概述
一、产品简介
794274-1 为 TE Connectivity（泰科电子）出品的一款四位电线密封件（密封塞），用于通用 MATE-N-LOK 接插件系列的线束密封。该密封件为蓝色硅橡胶材质，设计用于在插接点处对导线与接插件壳体之间的间隙进行密封，防止异物、湿气进入，保证连接可靠性与长期稳定性。
二、关键规格
- 类型：密封塞（电线密封件）
- 总 PIN 数：4（4 位）
- 绝缘层直径适配范围：1.52 – 3.3 mm（0.06 – 0.13 in）
- 工作温度范围：-55 – 105 °C（-67 – 221 °F）
- 颜色：蓝色
- 品牌：TE Connectivity（泰科电子）
- 适配系列：通用 MATE-N-LOK
三、材料与环境性能
本件采用硅橡胶（silicone）制造，硅橡胶在低温柔韧性与高温耐受性方面表现良好，适合温差较大的环境。硅胶通常具有优良的弹性和长期压缩回弹能力，用于密封件能保持密封性并适应多次插拔。工作温度区间与典型硅胶材料特性相符，适合航空、工业和运输等领域的环境要求。
四、装配与兼容性
该密封塞专为通用 MATE-N-LOK 系列设计，装配时应确认导线绝缘直径处于 1.52–3.3 mm 范围内。安装步骤通常包括：将密封件套入导线端并推进至插针位置，随后将带密封的导线插入端子/插座直至到位。安装过程中应避免划伤或拉扯密封体，以免影响密封性能。建议在长期储存或极端条件使用前检查密封件有无硬化、裂纹或变形。
五、典型应用场景
适用于需防护插接处的线束系统，如工业控制设备、通信接口、测控仪表、车辆及航空线束等场合；尤其在要求温度耐受范围较广、需重复插拔且要求良好环境密封性的场景中表现突出。
六、选型建议与注意事项
选型时以导线绝缘直径为首要依据，确保落在产品适配范围内；若需更高等级防护（如特定 IP 等级或化学介质暴露），应结合外壳与端子整体设计进行评估。储存应避光、避高温，使用前如发现弹性下降或表面缺陷应更换。购买时请以 794274-1 型号及 TE 官方资料为准，确保与目标 MATE-N-LOK 配套件相匹配。

Product sourcing intelligence
Model, package, availability, and BOM fit reviewed before quotation.
WMSIC turns product data, package visuals, BOM context, and sourcing signals into practical RFQ notes for buyers.
BOM matching & alternatives
BOM lines are compared by package, parameters, quantity, and workable alternatives for cleaner sourcing decisions.
Sourcing availability signal
Stock routes, quotation confidence, lead-time notes, and shipment feasibility are checked before sales follow-up.
Buyer sourcing scenarios
Examples of how common component sourcing requests are organized.
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.
