Diffuse
Category Selection
Diffuse photoelectric sensors feature an integrated emitter and receiver in a single compact housing. These sensors detect presence, distance, color, or contrast by emitting a light beam and sensing the light reflected directly from the target. They offer reliable performance, simple installation, and easy adjustment, but their sensing distances are typically shorter.
