Product Code:SAE AS5258/3
Title:Insulating Components, Molded, Electrical, Heat Shrinkable, Boot, Strain Relief and Sealing, Straight, Low Profile
Issuing Committee:Ae-8c1 Connectors Committee
Scope:The complete requirements for acquiring the molded components described herein shall consist of this document and the latest issue of AS 5258.Product Code:SAE J2577
Title:Heavy Duty Lamp Electrical Connector Standard
Issuing Committee:J2577 Heavy Duty Lamp To Connector Interface Task Force
Scope:This SAE Standard encompasses connectors that form the electrical interface(s) between the heavy duty lighting device(s) and the truck and truck/trailer wiring harness system. This document provides design and performance requirements based upon the mechanical, electrical and environmental conditions and covers applications of connectors for direct current electrical systems of 24 V nominal or less in heavy-duty signaling and marking devices. This standard excludes forward lighting devices (i.e. fog lamps) but includes the following list of lamps:-Stop Lamps-Back Up Lamps-Tail Lamps-Side-Turn Signal Lamps-Turn Signal/Hazard Warning Lamps-Work Lamps-Side Marker Lamps-License Lamps驴Clearance Lamps驴Chassis Component Status (ABS) Lamps驴Identification Lamps
