Documented Sensor Model
AESD18400SPO
M18 Diffuse Photoelectric Sensor, 400 mm
General-purpose threaded M18 diffuse sensor for industrial object detection.
Representative imageOverview
AESD18400SPO is a threaded M18 diffuse-reflection sensor intended for routine object-presence tasks. Its adjustable sensing range and detachable M12 connection suit production equipment where setup and replacement access matter.
Target size, surface finish, and reflectivity should be validated in the intended mounting position.
