9-Position IDC Receptacle for 30 AWG Discrete Wire
The JST SR series 09SR-3S is a 9-position single-row receptacle that terminates 30 AWG discrete wire via an IDC (insulation displacement) slot — no crimp tool, no terminal separate from the housing. The closed-end feature blocks the housing from being inserted backward into the mating header, a common assembly error on open-end receptacles. Tin-plated contacts match the cost profile of high-volume consumer and industrial internal wiring where mating cycles stay under a few dozen.
Position Count vs SR Siblings
The 09SR-3S carries 9 positions against the 7 of the 07SR-3S and the 10 of the 10SR-3S, all at the same 1.00 mm pitch with identical IDC termination and tin plating. The choice is purely a circuit-count match to the BOM — no footprint or tooling change across the three.
