Last week Belgian fabless chip company Melexis announced a unique inductive sensing IC that includes a tiny transformer, drive circuit and sense circuit, so Electronics Weekly decided to have a closer look. No permanent magnet, external or internal, is needed, and external magnetic fields are rejected. MLX92442 only requires a nearby electrically conductive object for triggering. It comes in either ...
There is a novel sort of bicycle dynamo that holds a strong magnet loosely in a little box next to the wheel rim. Once the wheel starts to rotate, the magnet’s field starts to interact with the passing aluminium (it only works with aluminium wheel rims) and the magnet starts to spin around in its box. A coil around the ...
Johanson Dielectrics is offering a range of novel multi-layer ceramic devices that combines two balanced shunt capacitors with mutual inductance cancellation, and a certain amount of shielding.
