Keysight E4980A Precision LCR Meter
The Keysight E4980A Precision LCR Meter, with extremely high accuracy and speed, isthe ideal tool for research and development, as well as manufacturing test.
Electromagnetic MEMS Optical Switch Actuators
For MEMS optical switches as well as other devices, the electromagnetic actuator is often used as the actuator of the movable part. A micro coil and magnetic material operate the object. The basic principal of operation is the same as that of a mechanical relay.
