The crossed-beam photogate uses a pair of infrared photogates oriented at right
angles to each other. This type of photogate
can be used to automatically actuate a camera shutter when an object passes
through the beam intersection. This makes it
useful for photographing birds and insects.
If a camera is centered and focused at the beam crossing,
the shutter will be actuated only when
the object moves through the point of focus. Click here for more information.
While triggering a camera is the most common application for the crossed-beam photogate, the circuit can also trigger flash units and wireless transmitters and can be connected to the external input of a Multi-Trigger in order to use the delay timer.

The CBP2-E kit includes the parts for all control box, wires, and cables. See the parts list here and assembly instructions here.
The CBP2-F kit includes the parts for a 10-inch square frame for the sensors. See the parts list here and assembly instructions here. (We sell the frame kit separate from the PCB kit in case you want to build a frame of a different size. We have successfully tested frames up to 12" square.)
A shutter cable is required in order to use the Crossed-beam Photogate to actuate a camera shutter. In order to trigger a wireless transmitter, see the 3.5mm male-to-male cable.
We provide shutter cables for most camera makes/models for use with our triggers. When you order a shutter cable, we include an extension cable and adapter, if needed, to convert the cable for use with the 3.5mm stereo jack on our triggers.
Select your camera make/model below and note the corresponding ID. If you don't find your model listed, compare the socket on your camera to the photos below. The photos will enlarge by clicking on them. If you are still unable to determine the type of plug that you need, please contact us. If you already have a shutter release and want to convert it for use with our triggers, this page may help.
All shutter cables, which include extension cords and adapters (if needed), are $12.95.

This AC/DC wall adapter provides a substitute for a 9V battery
to power many of your HiViz.com circuits. The adapter accepts 100-240V input
voltage at 50-60 Hz; output is a regulated 9 VDC.
The power rating is 10 W. The AC plug is a standard 2-pin non-polarized US plug. An adapter may be needed for some countries.
