Taiss Photoelectric Beam Sensor E3JK-R4M1 Indoor Wall Mounted 12-240VDC 24-240VAC Retroreflective photoelectric Sensor Switch Proximity Switch 2M Cable Induction 3M

If you're looking for the same prop trigger this is it for a great value.

It works really well - paired with a 12v DC LED light to indicate when a door is open. The instructions are almost useless so be very careful & methodical when installing. The polarity doesn’t matter for power to the sensor - polarity DOES matter for the switch AND (I found) for the LED light I connected it to. Also, because I’m working in short distances for the indicator I found it works better without the supplied reflector, which was too good for what I wanted; a strip of reflective tape does the job so the light goes on when the door is fully open & goes off as it closes. It took a number of tries to figure out the connections (a review I read said polarity didn’t matter) but now it’s working it does exactly what I wanted.

Works good and as advertised. Satisfied and recommend.

misleading pos. just installed it, and it doesn't work. the beam is not operating more than 3 feet. so, if you have a 3 feet power gate opening, you're ok. but if yours is a standard 10- 15 feet you are screwed. now I cannot return it and i am out of my hard-earned money.

Omron knock-off or at least from the same factory or something... it does not use omron switches or relays but operates exactly the same... but the effective distance of this product makes it a complete waste of money if you are trying to use it for absolutely anything other than a hallway traffic monotor or buzzer trigger when someone passes by it. cant use outside of 7 to 10 feet. shame. it is a pointless limitation.

No complaints.

Product worked as advertised out to 4 meters. Product description did not clearly show the limitation, my requirement was 5 meters (the width of a double garage door). Very frustrating. You should consider offering a 5 meter version and insure the product description clearly shows detection range.

Great value for Photo eye. Was packaged with hardware for most applications. Pay attention to the wiring schematic in the included documents. I am using it to turn of a 3 amp air curtain for our food truck when we present orders through the window.
