E3T

Miniature Square Photoelectric Sensor in plastic housing

E3T

• Precision pinpoint LED

• 3.5 mm thin flat shape or 6.6 mm side

view shape where space is crucial

• IP67

• Pulse synchronisation for high

ambient light immunity

Features

3.5 mm flat model with background supression (BGS) with highest repeatability even for differently coloured
objects.

Application

Object detection through small holes

• The precision pinpoint LED of the through-beam models

provides appropriate sensing distances for very precise and
reliable detection even through smallest slits and gaps with
e.g. 0.5 mm dia.

• 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).

Minimal black/white error

Unique light receiving lens shape

for high precision alignment

New mounting technology for reliable background

suppression in 3.5 mm flat housing
