Product details

2.00 mm Pitch In-Line Adapter for PH Series Harnesses

The JST B4B-PH-TW-S(LF)(SN) is a 4-position, in-line plug-to-plug adapter from the PH series, built on a 0.079" (2.00 mm) pitch. It terminates both ends as a plug with male pins, making it a pass-through adapter for joining two PH-series receptacle cable assemblies end-to-end. The free-hanging (in-line) mount means it lives in the cable run, not on a board — useful for extending a harness or splitting a signal path without a PCB.

The 4 positions match a 4-circuit BOM line exactly.

Frequently asked questions

What is the pitch of B4B-PH-TW-S(LF)(SN)?

What connector mates with B4B-PH-TW-S?

This adapter has male pins on both ends, so it mates with PH-series receptacle housings (female contacts) on each side.
