4-Position IDC Receptacle for 30 AWG Harnesses
The JST 04SR-3S is a 4-position IDC receptacle from the SR series, designed for mass-terminating 30 AWG discrete wire without stripping or crimping. Tin-plated female sockets are rated for the contact resistance of a low-cycle harness; the closed-end housing prevents wire poke-through on the last position.
Position Count and Sibling Options
The 04SR-3S sits in a single-row family that runs from 3 to 6 positions at the same 1.00 mm pitch. If the BOM calls for 4 circuits, this is the match; a 5-circuit harness steps up to the 05SR-3S without changing the wire gauge or tooling.
The lifecycle status is Active and RoHS3 compliance is confirmed.
