Our 3.96 mm three‑row machined pin header is a high‑reliability board‑to‑board / board‑to‑cable interconnect purpose‑built for CNC machine tools, PLC systems and heavy‑duty industrial controllers. Unlike conventional stamped pin headers, it adopts full CNC machined solid contacts to deliver superior mechanical stability, low contact resistance and consistent performance under vibration, temperature cycling and repeated mating cycles. Three‑row layout maximizes I/O density within limited PCB footprint, handling mixed signal and low‑power circuits for factory automation equipment. Fully RoHS & REACH compliant, supports through‑hole DIP soldering for industrial‑grade assembly conditions.
