Relatively adverse conditions atmosphere there is a water mist in the painting line, to detect the stable to the hanger bar to water droplets adhere to the reflection plate. (Open slits corresponding to SasageFutoshi of the reflecting plate) Sensor and the reflector of the interval: 1.5m Reflection plate easy to light can be optical axis alignment visibility to be projected to. The power supply voltage is AC-DC 24V ~ 240V, adapt to most of the control circuit. Dry contact output is also welcome.

Wiring is also a simple, is good not of the kind of power. To MonotaRo buttocks. There is also the handling of E3JK-R2M1 of the same type, but the difference did not know well. When the difference of the light-shielding during ON and ON when light enters asked to appear in the selection list of the list, it was easy to select.
