"Mini" Photoelectric Sensor
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.
