The TrainSpotterM senses true motion of a train moving over the sensor. Features Small size (0.25" x 2.25") Simple, discrete under-track installation Two outputs, one for each dire ction 24" pre-stripped wire leads attached to the sensor Powered from 5V to 24VDC Optional mounting bracket available Typical Applications Flange squeal Station announcements Installation 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. A mounting bracket can be found here. Electrical Connections The TrainSpotterM needs 5 to 24 volts of clean direct current (DC) power to operate. Two outputs are provided, one activates for "left" motion and the other activates for "right" motion. Both outputs are “open drain” (otherwise known as “open collector”) and act like a switch to the ground or 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.
