Water mist in the painting line There is a relatively bad condition, water droplets adhere to the reflector Stable detection of the hanger bar. (Open slit according to bar stiffness on reflector) Space between sensor and reflector: 1.5 m Light projected on reflector is visible and easy to align optical axis. Supply voltage is AC 24V ~ 240V, suitable for most control circuits. Dry contact output is also appreciated.

Wiring is also easy, it is good not to choose the type of power supply. To MonotaRo. There is also handling of E3JK-R2M1 with the same type, but I did not understand the difference. It was easy to select when you show the difference between ON at the time of incoming light and ON at the time of light blocking on the selection list of the list.
