20-position IDC receptacle for 36 AWG discrete-wire harnesses
The JST 20XSR-36S is a 20-position, single-row receptacle in the XSR series, terminated via IDC to 36 AWG discrete wire. The 0.024" (0.60mm) pitch packs the 20 circuits into a narrow body — suited for high-density harnesses where board real estate is tight. The natural housing includes a closed end to prevent wire push-through and an integrated strain relief that protects the IDC termination from cable pull during assembly and service. Tin-plated female sockets mate with the corresponding XSR pin header; the free-hanging (in-line) mounting lets the connector sit anywhere along the wire bundle, not just at a board edge.
IDC termination for 36 AWG — no crimp, but wire prep matters
This connector uses insulation-displacement contacts rated for 36 AWG discrete wire. The trade-off is that wire diameter must stay within the slot tolerance; 36 AWG is the listed gauge, and the closed-end design means each wire seats fully or not at all. The strain relief adds mechanical retention at the cable exit, which matters when the harness sees flex or vibration in a cabinet or portable device.
Position count variants in the XSR series
The 20XSR-36S sits between the 16-position (16XSR-36S) and 22-position (22XSR-36S) members of the same XSR IDC family. All three share the 0.024" (0.60mm) pitch, single-row layout, tin contacts, and natural housing with closed end and strain relief. A 10-position variant (10XSR-36S) is also in the series for lower-density runs.
No official cross-reference or direct second-source is listed; the JST XSR series is the sole supply path.
