Right-angle 8-pin header with shrouded protection
The JST S8B-PH-K-S is an 8-position, single-row header from the PH series, designed for board-to-cable/wire interconnects. The header is shrouded on all four sides (4-wall), protecting the male pins from bending during mating and preventing misalignment — especially useful when the connector is mated blind or in a harness assembly jig. Rated at 2 A per contact and 100 V, with a detent lock that provides a positive hold against cable pull and vibration. Operating temperature range is -25°C to 85°C, covering most indoor and outdoor commercial applications but not extended for engine-compartment heat.
Board layout and mounting fit
The right-angle orientation routes the connector parallel to the PCB, saving z-height in tight enclosures. The through-hole termination uses press-fit tails that provide mechanical retention before soldering; the solder joint carries the electrical connection. Contact length on the mating side is 0.130" (3.30 mm), and the post length is 0.134" (3.40 mm). Insulation height above the board is 0.189" (4.80 mm), which sets the keep-out zone for adjacent components.
Position count comparison within the PH series
The S8B-PH-K-S sits between the 7-position S7B-PH-K-S(LF)(SN) and the 9-position S9B-PH-K-S(LF)(SN) in the same right-angle, shrouded, single-row PH family. If your BOM needs 8 positions, this is the direct fit.
