281934-2 产品概述

一、产品简介

TE Connectivity(泰科电子)281934-2 是用于 AMP 1.5 mm 超密封系列的单线密封件(Single Wire Seal,SWS),颜色为黄色,材质为硅胶。该密封塞设计用于在连接器线缆进入点提供可靠的环境密封与应力缓冲,适配腔体直径为 5.5 mm(0.217 in)的孔径结构,常用于对密封、耐温与耐久性有要求的线束应用。

二、主要参数

  • 类型:密封塞(单线密封件,SWS)
  • 品牌:TE Connectivity(泰科电子)
  • 系列:AMP 1.5 mm 超密封系列
  • 腔体直径:5.5 mm [.217 in]
  • 工作温度范围:-40 – 130 °C [-40 – 266 °F]
  • 颜色:黄色
  • 材料:硅胶(弹性体)
  • 型号:281934-2

三、材料与性能特点

采用硅胶弹性体,具备以下典型性能:

  • 宽温域工作能力:在 -40 至 130 °C 范围内保持弹性与密封性,适合低温与中高温环境。
  • 良好的弹性回复与压缩保持性,能够在插拔与振动条件下维持密封界面。
  • 抗老化、耐候性好,对臭氧和紫外线有较强抵抗力(常见硅胶特性)。
  • 对多数润滑油、冷却液和一般化学品表现出良好耐受性(具体介质兼容性建议按实际工况验证)。

四、主要优点

  • 与 AMP 1.5 mm 系列配套性强,插装简单,可实现单线级别的密封保护。
  • 柔软且耐温,能减少导线应力集中,延长线束寿命。
  • 黄色标识利于装配识别与质量检查。
  • 结构紧凑,适应空间受限的电气连接场合。

五、典型应用场景

  • 汽车线束与车灯、传感器连接器的密封件。
  • 工业控制、户外设备的防护连接点。
  • 需要防尘、防水或防潮的电子电气接口处。
  • 其他对温度和耐久性有一定要求的线缆密封场合。

六、装配与使用建议

  • 在装配前确认腔体尺寸与插针线径与本件匹配(腔体直径 5.5 mm)。
  • 装配时建议在密封件上使用少量兼容润滑剂以降低摩擦并保护密封唇口(需确认润滑剂与硅胶兼容)。
  • 避免锋利工具直接划伤密封件表面;插装过程中保持零件清洁,防止颗粒物嵌入影响密封性。
  • 如有多次拆装需求,应检查密封件压缩恢复情况,发现裂纹或硬化应及时更换。

七、储存与注意事项

  • 建议在干燥、通风、阴凉处存放,避免长期暴露于强光或高温环境。
  • 存放时远离有机溶剂、高浓度酸碱和油品等可能损伤硅胶的介质。
  • 长期库存后使用前应检验外观与弹性,确保无老化或变形。

八、兼容性与替换建议

281934-2 专为 AMP 1.5 mm 超密封系统设计,若需替换或选型,请以该系列规范为依据,确认线径、腔体直径与工作环境要求。对于特殊化学介质或极端温度工况,建议向 TE Connectivity 技术支持或材料供应商确认兼容性与性能保证。

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.

Package confirmation Typical RFQ workflow

A multi-line BOM is organized into direct sourcing lines, lines that need package clarification, and lines where alternative-part review is permitted.

Mixed BOM triage Typical RFQ workflow

The original manufacturer part number, datasheet revision, application, critical limits, and acceptable changes are collected before possible candidates are discussed.

Obsolete-part review Typical RFQ workflow

Sample quantity, minimum packing, package format, target date, and courier destination are kept together in one RFQ conversation.

Small-batch request Typical RFQ workflow

Package photos, model markings, board context, and the quantity needed for repair help focus the sourcing review on the relevant version.

Repair batch evidence Typical RFQ workflow

When a suffix or package note is incomplete, the response records the open difference and requests buyer confirmation before procurement proceeds.

Model suffix clarification Typical RFQ workflow

Packing format, carton notes, invoice details, courier option, destination, and tracking handoff are coordinated around the confirmed order.

Export handoff Typical RFQ workflow

The request connects the previously used model, current demand, package evidence, target timing, and replenishment sourcing route.

Replenishment inquiry Typical RFQ workflow
