The 3525 uses the most reliable and accurate style of photoelectric sensing which is the through beam sensor. The sensor comes with an emitter and a receiver. The emitter provides a constant invisible IR (infrared) beam of light to the receiver and detection occurs when an object passing between the two breaks the beam. The photo detection range of the 3525 is up to 10 meters.
A very familiar application of a through beam photoelectric sensor can be found is right in your home. Quite often, a garage door opener has a through beam photoelectric sensor mounted near the floor, across the width of the door. This sensor is making sure nothing is in the path of the door when it is closing.
The Phidgets Digital Input is "off" when the receiver receives the transmitter signal (i.e. there are no objects between the transmitter and the receiver); the Digital Input is "on" when the beam is broken by the presence of an object.
You need to provide 12VDC to the transmitter. The brown wire is +V and the blue wire is GND. The reciever connects to any device with a Digital Input. See the "Compatible Products" tab for details.

This is how you use an external power supply to connect the 3525 to a Phidget InterfaceKit or Hub that does not have an external power jack:
Note: When the 3525 is connected to a board with open-collector digital outputs like the 1012, it will behave as a Normally Closed (NC) sensor instead of Normally Open (NO). You'll also need to use a pull-up resistor when using a 1012. A 1kΩ resistor between the brown and black wires will work.
For boards that have power input, if the supplied power is within 12-24VDC, the +V line can be connected to the terminal block, powering the sensor through the Phidget.
