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.","metaTitle":"JST JMC 40RF-JMCS-G-1B-TF(N)(LF)(SN)","metaDescription":"JST JMC series 40-position FFC/FPC receptacle, 0.020\" (0.50mm) pitch, gold-plated contacts, SMT.
