Features

Accuracy

e3t accuracy prod

Minimal black / white error

Precision

e3t precision prod

The coaxial optics and the small focal lens of the retro-reflective models allow the detection of small (dia 2 mm) objects or through small holes (dia 2 mm).

Technology

e3t technology prod

The unique light receiving lens shape and the new chip mounting technology, provide appropriate sensing distances for very precise and reliable detection even through smallest slits and gaps with e.g. 0.5 mm dia.

Mounting

e3t m2 m3 mounting prod

Models with M2 or M3 mounting holes.
