Cognex MVS-8100D and CDC Cameras Hardware Manual
Hardware Trigger and Strobe Connections
Cognex CDC series cameras support hardware-based trigger initiation of image
acquisition and the simultaneous activation of a photo strobe to illuminate the scene
under the camera at the instant of acquisition. Wire your trigger and strobe devices
directly to each CDC series camera, not to the MVS-8100D frame grabber.
Cognex software determines whether the hardware trigger and strobe feature is
enabled. You can enable hardware triggers and strobes independently of each other.
Cognex software also provides software-based trigger and strobe control.
Figure 27 shows the pin numbering of the trigger-strobe connector on the back of CDC
series cameras.

Use Cognex cable 300-0362 to connect trigger and strobe devices. One end of this
cable terminates in a Molex Sherlock 2.0 mm pitch (0.079” pitch) four-pin header, Molex
part number 35507-0400. The Molex connector locks into place in the corresponding
four-pin connector on each CDC-series camera. The other end of the cable terminates
in four color-coded wires with tinned ends, each labeled as shown in Table 23.
Cable 300-0362 has a shield ground wire extending from the base of its Molex
connector. Connect this ground wire to the screw on the upper right corner of the back
of the CDC series camera.
