E3S-BT81 Photoelectric Sensors NEW

E3S-BT81 Omron Photoelectric Sensors NEW

Product Description:

Revolutionary High-performance High-quality Sensor with Built-in Amp

· Optical axis can be adjusted in seconds because the optical axis coincides with the mounting axis.

· Highly visible spot on white paper (except 10-cm and 70-cm Diffuse Reflective Sensors).

· Two-turn sensitivity adjustment with consistent scale reading to enable setting multiple sensors without adjusting each individually (for Diffuse Reflective Sensors).

· Stable detection at a distance of from 0.2 to 70 cm (E3S-ADj2, E3S-ADj7).

· Washable in water (IP67, NEMA 4X enclosure rating).

· A total of 72 different modes to match essentially every need.

· Built-in mutual interference prevention function.

· E39-E6/E8 Filters for mutual interference prevention available.
