Product details

FFC/FPC Receptacle for Fine-Pitch Board Interconnects

The JST 40RF-JMCS-G-1B-TF(N)(LF)(SN) is a 40-position FFC/FPC receptacle from the JMC series, using a 0.020" (0.50mm) pitch dual-row contact layout. It is a surface-mount connector with gold-plated center strip contacts, designed for flex-circuit or flat-flexible-cable termination.

No direct replacement order code is listed in the lifecycle record.

The 0.50 mm pitch places this connector in fine-pitch FPC territory. The dual-row arrangement packs 40 circuits into a narrow body, which suits high-density signal routing in compact handheld or display assemblies.
