Seco-LarmE-931-S35RRQ NIR Reflective Photoelectric Sensor (Pack of 2); For outdoors gates, garage doors, etc; Weatherproof (IP66) construction for indoor/outdoor usage; Adjustable sensing distance

Q: This will work on ghost control systems

We asked the Manufacturer and they replied: "We’ve had these units used in “haunted houses” to control some of the displays to scare people. But not entirely sure of what they are asking for."

Q: What is the ambient illuminance rating for the reflective photoelectric sensor?

We asked the Manufacturer and they replied: "It is an IR sensor so we would say no ambient illumination."

Q: Do they operate in daylight ? What is dark on ?

Yes, they work in daylight. The Dark-On/Light-On has to do with the relay status when the unit is powered off.
