Sensor Head D1.2/F18

Sensor Head D1.2/F18

Ø 1.2 mm, length 7.5 mm

With its extremely small diameter the D1.2/F18 sensor head is perfectly suited for vibration and displacement measurements at confined machine spaces. Despite the focusing optics and the miniaturization, the sensor head allows travel ranges of more than 5 mm at relatively high working distances, e.g. 30 mm on mirrors.

It is also compatible for low reflective targets, like glass or polished steel. The slim design allows a dense arrangement of the sensor heads and therefore minimum distances between multiple measurement points.
