E3T

Features

Photoelectric sensor in miniature plastic housing

Small sized photoelectric sensors in flat and side view shape for demanding mounting conditions.

  • Small size with precision pinpoint LED where space is crucial
  • 3.5mm flat model with reliable background suppression and small black/white error
  • Unique optical alignment technology ensuring minimal deviation of optical axis
  • High EMC and ambient light immunity

For smaller size see the E32 Square Shape.

Accuracy

Minimal black / white error

Precision

E3T_precision.jpg
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.jpg
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.

1. For pre-wired models with robotic cables add '-R' to the order code (example: E3T-FT21R 2M)

2. The distances are measured with reflector E39-R4 and reflective foil E39-R37-CA. For applications with shorter distances between the sensor and the reflector contact your OMRON representative.

3. Order reflector separately. Models with included reflectors are available.
