Differential Eddy Current Sensors SCE-2200
Available for Single, Dual channel configurations，analog out
Fig.1 SCE-2200
Applications：
- Fast Steering Mirrors (FSM)
- Telescope and microscope stabilization
- Image stabilization
Controllers
- Controller SCE-2200
The standard controller SCE-2200,shown in fig.1, is the electronics in an Aluminum box, 4 MCX connectors for the sensor, and the I/O connector is a 9-pin mini-D connector.

Sensor Probe
Standard version sensor probe S0523, default line length 1.5m, with straight MCX connector,usually in stock. Optional versions S0518,S0523L and S0514 P, the default line length is 0.5m, can be customized according to customer requirements. By default, the connector is MCX straight, MCX 90-degree elbow is optional, and other connectors such as SMA connectors can also be customized.
