E3T-FL1@
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).
