CKT-IRSENSE is a low-profile reflective infrared sensor utilizing the latest in proximity sensing technology.
The detector is designed to be installed up through the benchwork in a 3/8 inch (10 mm) hole. Because the sensor itself is so small, only a single hole is required and no complicated drilling jigs are needed. The sensor can be secured in the hole using a variety of methods such as hot glue or by using a bracket. An example mounting bracket can be found here.
The CKT-IRSENSE needs 5-24 volts of clean direct current (DC) power to operate. Two opposite polarity outputs are provided, both of which are “open drain” (otherwise known as “open collector”) and act like a switch to the ground / negative lead.
Logic level outputs can be generated by connecting a resistor to pull up the output to the positive supply. Other devices, such as LEDs or relays can also be driven directly and the outputs from multiple sensors can be connected in parallel to combine them into one signal.
The release time is variable from 0.1s to 23s (Normal Delay Option) or 6s to 23 minutes (Long Delay Option) using an external resistor. See the user manual for details.
The activation time is preset to 0.1s. The sensing distance varies with the reflectivity of the object being sensed, but is typically 1.5". Both can be modified using custom firmware - contact us for details.
