“Mini” Photoelectric Sensor E3T
High cost-performance “Mini”
Photoelectric Sensor Saves Installation
Space and Wiring Effort and Detects
Minute Sensing Objects
“Pin-point” beam (1 to 2-mm dia.) makes it possible
to detect minute sensing objects.
Saves wiring effort, even with compact body.
Work steps can be reduced to half with the
retroreflective or limited reflective model.
Easy-to-use with a clearly-visible “Pin-point” beam.
Long sensing distance of 1 meter is possible with
the through-beam model.
