Electric Eddy-current Displacement Sensor


Description:

CJDY Eddy-current Displacement Sensor can convert mechanical displacement, vibration amplitude and rotation rate into electrical signals to output. Sensing head, proximitor, extension cable and measured conductor composes eddy-current displacement sensor.
It is an ideal non-contact sensor for measuring displacement, amplitude and rotation rate.

Prefix installation

1, floor installation, 51mm x 51mm, installation of four M4 x 12 bolts

2, the guide rail installation, can be conveniently installed on the standard 35mm guide rail.

The connection between the Proximitor and the probe cable

Use SpringLoc terminal,has automatic fastening function,

No need installing tool and can be connected,because the bolt does not need to be fixed, no loosening
