Connector Selection for Rail, Robotics and Industrial Automation
Rail, robotics and factory automation look like three markets but impose the same four stresses: sustained vibration, repeated mating, fluid exposure and wide temperature swing. Ranking those four correctly is what separates a connector that lasts from one that becomes a maintenance item.
RF Coaxial Connector Selection Guide: SMA, SMB, MCX, MMCX, N and BNC Compared
Six 50 ohm interfaces cover the overwhelming majority of RF and microwave work. They differ in frequency ceiling, coupling method and power handling — and picking the smallest one that fits is usually the wrong instinct.
Hengyu Consolidates RF Coaxial Portfolio Under GJB681A-2002
Guangzhou Hengyu Electronic Technology Co., Ltd. now offers its principal RF coaxial families against a single qualification reference — GJB681A-2002, the national military standard equivalent to MIL-C-39012 — giving designers one document set across six interface types.
